I am looking for a open source library in Java for HTML Microsoft Word conversion. I have found many tools for Word to HTML conversion but not too many for converse.
I'm trying to copy a 200GB file from an NFS mount to a local disk. The local disk is an XFS filesystem on a LVM on top of a RAID 5 system (hardware RAID controler).
I'm using rsync to monitor the transfer speed. At the beginning the IO speed is about 200MB/s, stable for the first 18GB. But then the performance drops by a factor of 10-20 and never recovers to the initial rate. Sometimes it reaches about 50-100MB/s but just for a few seconds and then the process seems to hang for a bit.
At the same time all file-stat operations on the target filesystem are blocking for a long time (minutes). Also interrupting the copy process blocks for several minutes, a sub-sequent delete of the partly copied file takes also several minutes.
Any ideas what could be causing this?
My laptop came with a 500 GB hard drive. I use my laptop for storing my digital photographs, and only have about 14 GB of file storage left on the original hard drive. I have a 750 GB external hard drive, but am leery of relying on it for primary storage as I tend to knock things over and it has already crashed once and I lost a lot of the files. I am looking at a 1 TB internal hard drive, but am concerned if storing so much data will affect the computer's performance. Should I also increase RAM from 4 to 8 GB (the limit for my 64-bit, Windows 7, Asus A54C laptop)?
I am currently switching from a system with HPN-SSH tunnels and enabled compression to something VPN based. I have tried tinc and n2n so far, hamachi requires a library I do not have.
In my primitive benchmarks I am not satisfied with the achievable bandwidth compared to the SSH tunnels. In tinc the low LZO setting performed best, but compression is only available in UDP mode.
Ideally I would like to have a TCP-based VPN with a multi-threaded compression.
Can you suggest me some ideas how to increase the performance? Would it be possible to somehow put a compression filter in front of the tun interface? Or are there any VPN implementations that might be better suited for my needs (fast compression, TCP-based, switch mode, does not have to be super-secure)? I would consider tunnelling Ethernet over SSH, but according to some articles it is not advisable.
Ignoring all the characteristics of each languages and focusing SOLELY on speed, which language is better performance-wise?
You'd think this would be a rather simple question to answer, but I haven't found a decent one.
I'm aware that some types of operations may be faster with python, and vice-versa, but I cannot find any detailed information on this. Can anyone shed some light on the performance differences?
Is there a way to either disable Internet Explorer 8 Developer Tools, or at least change the shortcut key mapping?
I'm working on an ASP.NET AJAX app that has used the F12 key for a function for years (it's actually a hold over from the original DOS app). Customers have used this key for the sam function for nearly 15 years and we'd really like to avoid having to move that function.

I love the new live event in jQuery 1.3. The question I have is the performance of this event. I know the advantages of using live over click/bind('click') but is there a performance hit for using it over click/bind('click')?
If not, why would you ever use click or bind('click')?
Hi guys, I used jQuery tools to create a tabs setup, and I would like to incorporate the fade effect, but when I try to do so, it bombs out, here is my code:
$(function() {
$("#flowtabs").tabs("#flowpanes > div", { history: true, effect: 'fade' });
});
I am assuming that it's because I am also enabling the tabs history?
I am kinda new to all of this, so please be patient! :-)
Thanx in advance!
Got the 32bit and 64 bit versions of the Intel VTune Performance Analyser. I installed the 64bit version (I think the installed was the "EMT" one) and when I go to create a new project, upon clicking the button to select an executable to profile, no file dialog popup shows.
I got an old laptop and installed the 32bit on to Windows XP and it works fine.
Regarding the 64 bit version, I did try changing the compatability to XP SP3 but it still didnt work.
Does anyone know how to fix this?
It is good idea to have impotant information during developing like Landau notation to know functions's time costs. So it should be documented in sources isn't it?
I'm looking for tools that can calculate it.

Hi,
What tools can I use to debug mobile webkit sites?
Is there a better tool than "Firebug for iPhone" or is "Firebug for iPhone" pretty much the best tool out there?
Thanks,

Are there any CASE-tools for Erlang which help to improve the process of software development, in particular the process of automatic code generation based on information in various diagrams (IDEF, DFD etc.) ?
Hello.
I need to create a prototype of ui.
I'm googling, and find "Axure RP", but it very expensive for us company.
Other way for creating UI prototype is tools like Qt Designer, but it doesn't provide some cool functions and sometimes demand bit programming skills.
Do you know freeware tool for my task for man without any programming skills?
Thanks.
Ps. excuse my english ;)
I have an application which intensively uses DB (SQL Server).
As it must have high performance I would like to know the fastest way to insert record into DB.Fastest from the standpoint of execution time.
What should I use ?
As I know the fastest way is to create stored procedure and to call it from code (ADO.NET).
Please let me know is there any better way or may be there are is some other practices to increase performance.
Can you recommend any programmable tools/extensions that can be used to generate reports out of google analytics feed on th fly? Essentially some kind of pdf generator from feed, not sure though.
Or does the Google analytics itself gives reports output as feed etc.,
Possible Duplicates:
i5 vs. i7 processor dev laptop
Developer Notebook i5 or i7
I could not decide on which configuration below gives better performance for developers on a notebook(running VS.NET, SQL Server, no gaming);
(A) i5 540M + SSD (Intel) or (B) i7 720M + 7200 RPM HDD (Western Digital)
Since these two configurations(A, B) costs nearly same $ for me, I would like to buy the fastest one for my job environment.
Please do not comment just buy this or that, if you can give an inference about your choice I would be appreciated.
Thank you,
cas
I have just asked which one is better?
Static Vs Non-Static?
http://stackoverflow.com/questions/3016717/static-vs-non-static-method-performance-c
I would like to take this discussion one step ahead.
Consider If i pass reference of Panel control as parameter to Public static method, will static method still rules in performance?
I'm using Lync 2010 server to handle some clients communication and screen sharing. The biggest issue is the performance with screen sharing, it is of rather high quality but the frame rate is very poor.
I have been reading and searching a lot on the subject and 95% of all topics is about bandwidth, we have a 200/200 MBit Internet connection solely for this application. Also my test machines runs on an internal gigabit lan. The speeds between all boxes is hysterically fast.
Next step was to ensure that there where some profiles for different bandwidths, so i registered some
New-CsNetworkBandwidthPolicyProfile -Identity 50Mb_Link -Description "BW profile for 50Mb links" -AudioBWLimit 20000 -AudioBWSessionLimit 200 -VideoBWLimit 14000 -VideoBWSessionLimit 700
New-CsNetworkBandwidthPolicyProfile -Identity 100Mb_Link -Description "BW profile for 100Mb links" -AudioBWLimit 30000 -AudioBWSessionLimit 300 -VideoBWLimit 25000 -VideoBWSessionLimit 1500
Nothing fancy happend here either.
Non of the test boxes have anything from Norton installed, they doesn't have any firewalls running (nor does the Lync server), all fences are down in this environment just for the testing.
Is there any thing that I may have missed to improve the quality of this?
Thanks
I have a IPSec link between two sites over ASA 5520s running 8.4(3) and I am getting extremly poor performance when traffic passes over the VPN. CPU on the device is 13%, Memory at 408 MB, and active VPN sessions 2 so the load on the device is particularly low.
Screenshot of wireshark file transfer between the two hosts over the VPN:
The large amount of Header checksum failures is alarming, but I am not sure what to check now. I perf is showing around 4-5 Mbit/sec with differing TCP window sizes.

Which is the best Visual SVN Diff displayer for Linux.
BeyondCompare and VisualSVN1.5 work well on Windows. What are the equivallent tools for Linux. Specifically Ubuntu.
I know command line diff works; But I'd like multiple column syntax highlighted and differences.
Better if the tool has a support for Git and Hg as well.
I run multiple ARM boards with Debian Linux installed. Board is equipped with 512 MB of NAND memory. I've observed that after ~3 months of continuous run booting time increased significantly - it takes over 3 minutes to mount filesystem (JFFS2).
System was using about 35% of available storage so I’ve removed unnecessary files (got to ~18%) but this didn't change anything.
Then I realized that my software produces directories that are left empty so I’ve removed ~500 empty and unnecessary dirs. This didn’t help either.
After system is started I see JFFS2 garbage collector (jffs2_gcd_mtd4) running and occupying over 90% of CPU.
Now my question: is there a way to „optimize” JFFS2 filesystem for better performance - faster booting (my system have limited timid to boot up)? It would be great if this optimization could be done remotely - I have no physical access to boards.
Hello,
we have a new win2008-R2 (2x Xeon X5570, 32GB RAM).
There I have installed the terminal-server roles, thats all OK.
Currently 5 users are working at this server, but all get a very low performance in their remote-desktop session.
Sometime it takes 1-2 seconds till the keyboard-inputs will be performed and shown.
At the clients I run RDP v 6.1
We have also an older TS-server (based on Win2003 with an Opteron-CPU), there are working about 20 users at the same time. There I do not have the troubles with the inputs at the remote-desktop sessions.
Both servers are connected to the same gigabit-switch.
Any ideas what could cause the troubles at the Win2008 R2?
Many thanks in advance.
Regards
Chris
We have a Linux server process that writes a few thousand files to a directory, deletes the files, and then writes a few thousand more files to the same directory without deleting the directory. What I'm starting to see is that the process doing the writing is getting slower and slower.
My question is this: The directory size of the folder has grown from 4096 to over 200000 as see by this output of ls -l.
root@ad57rs0b# ls -l 15000PN5AIA3I6_B
total 232
drwxr-xr-x 2 chef chef 233472 May 30 21:35 barcodes
On ext3, can these large directory sizes slow down performance?
Thanks.
Aaron
