• Sempron 145 core unlocking

  - by Grant

  Call me a cheapskate looking for performance, but I have a Sempron 145 processor that has been unlocked to an Athlon II X2 4450e with a GIGABYTE GA-990FXA-UD3 motherboard, but only one of the two processor cores can be used at a time. If both of the cores are enabled in the BIOS the kernel will hang during boot, If I reboot the system and disable the second core (but not re-lock the processor), it will take me to the grub and then start normally. Is there a way to enable both cores and boot without kernel hangs?

  - by soporte.cs

I wonder which options should be active in ubuntu for this type of software to operate smoothly. Thank you.

• No Significant Fragmentation? Look Closer…

  If you are relying on using 'best-practice' percentage-based thresholds when you are creating an index maintenance plan for a SQL Server that checks the fragmentation in your pages, you may miss occasional 'edge' conditions on larger tables that will cause severe degradation in performance. It is worth being aware of patterns of data access in particular tables when judging the best threshold figure to use.

  - by Paul Tomblin

  I've written an extension to RequestTracker for a client, but he says the performance isn't good enough. I'd like to do some profiling, but I'm not sure how to connect up a profiler (say NYTProf, for example)? I tried what the man page says and put PerlModule Devel::NYTProf::Apache in my apache config, but all I get in the results are Apache2:XSLoader, Devel::NYTProf::Apache and ModPerl::Util modules in the results, and neither my own nor RT's modules.
