• Single Instance Storage layers

  - by Moo

  Hi, I have a data storage requirement which is an excellent candidate for single instance storage and deduplication. Can anyone suggest any .Net compatible libraries or systems which handles SIS and deduplication, either with SQL Server as an actual back end or its own high performance storage engine? What have peoples experiences been with such engines, and are there any pit falls to watch out for? Regards Moo

• System architecture: simple approach for setting up background tasks behind a web application -- wil

  - by Tim Molendijk

  I have a Django web application and I have some tasks that should operate (or actually: be initiated) on the background. The application is deployed as follows: apache2-mpm-worker; mod_wsgi in daemon mode (1 process, 15 threads). The background tasks have the following characteristics: they need to operate in a regular interval (every 5 minutes or so); they require the application context (i.e. the application packages need to be available in memory); they do not need any input other than database access, in order to perform some not-so-heavy tasks such as sending out e-mail and updating the state of the database. Now I was thinking that the most simple approach to this problem would be simply to piggyback on the existing application process (as spawned by mod_wsgi). By implementing the task as part of the application and providing an HTTP interface for it, I would prevent the overhead of another process that is holding all of the application into memory. A simple cronjob can be setup that sends a request to this HTTP interface every 5 minutes and that would be it. Since the application process provides 15 threads and the tasks are quite lightweight and only running every 5 minutes, I figure they would not be hindering the performance of the web application's user-facing operations. Yet... I have done some online research and I have seen nobody advocating this approach. Many articles suggest a significantly more complex approach based on a full-blown messaging component (such as Celery, which uses RabbitMQ). Although that's sexy, it sounds like overkill to me. Some articles suggest setting up a cronjob that executes a script which performs the tasks. But that doesn't feel very attractive either, as it results in creating a new process that loads the entire application into memory, performs some tiny task, and destroys the process again. And this is repeated every 5 minutes. Does not sound like an elegant solution. So, I'm looking for some feedback on my suggested approach as described in the paragraph before the preceeding paragraph. Is my reasoning correct? Am I overlooking (potential) problems? What about my assumption that application's performance will not be impeded?

• Is ASP.Net State Server an elegant solution?

  - by alchemical

  We have an ASP.Net MVC project that will start with a single web server but likely soon scale into a small web farm. As ASP.Net Authentication stores a UserID, and data caching may also be useful, we would likely need to make the jump to state server fairly soon. I'd like to hear from others how State Server has been to work with and how it scales from a performance perspective. Alternateively, we could architect it as completely stateless by not using data caching and tracking sessions with an encrypted cookie.

• ORM market analysis

  I would like to see your experience with popular ORM tools outhere, like NHibernate, LLBLGen, EF, S2Q, Genom-e, LightSpeed, DataObjects.NET, OpenAccess, ... From my exp: - Genom-e is quiet capable of Linq & performance, dev support - EF lacks on some key features like lazy loading, Poco support, pers.ignorance... but in 4.o it may have overcome .. - DataObjects.Net so far good, althrough I found some bugs - NHibernate steep learning curve, no 100% Linq support (like in Genom-e and DataObjects.Net), but very supportive, extensible and mature

• ModelVisual3D vs Model3DGroup

  - by bitbonk

  Is there any disadvantage of using ModelVisual3D over Model3DGroup. How much can the resource/performance impact possibly be? ModelVisual3D gives me much more than Model3DGroup does but AFAIK everything that can be done with Model3DGroup can alos be done with ModelVisual3D. So why not just always use ModelVisual3D?

• SoapUI JMS Connections

  - by Damo

  I am using SoapUI to do performance testing of some services over JMS using WebSphere MQ as the JMS Provider. SoapUI uses HermesJMS to provide the JMS Connection details for the JMS Endpoint. I've noticed that when I call a request from SoapUI the JMS Connection is never closed. This results in hundreds of SYSTEM.DEF.SVRCONN channel connections. It seems to be specific to SoapUI as HermeJMS doesn't exhibit this behaviour. Has anyone else seen this?

• Delphi 6 - Bugs disappear when I compile multiple times.

  - by Daisetsu

  My Delphi installation has been going downhill for the past few months. It seems though that every so often when I build a release it has strange errors in it which are resolved if I build, then compile, then build, compile, etc. I've talked to another developer who thinks that this is a compiler error. This sort of degrading performance over time has happened on other computers to us too. What does stack overflow think could be the problem.
