Don't have a question, but thought I'd leave a tip. I've been running XP since beta 2 and didn't know this. Kinda ticks me off. Hope it might help somebody else. For users of Windows 2000 or XP you actually have to tell the OS what size L2 cache your processor has otherwise it won't be used properly! Luckily it's fairly easy to fix.

Click on the Start button then go to run. From there type REGEDIT and press the "Ok" button. After it opens the Registry Editor follow this path. hkey_local_machine, System, CurrentControlSet, Session Manager, Memory Management

Once you're in the Memory Management folder look for the DWORD value
secondleveldatacache.
Right click on that and go to modify. Very important you have to change the Base from Hexidecimal to Decimal before modifying the values. After that's done just punch in your L2 cache size so if you're using an AthlonXP since the CPU has 256KB L2 Cache you enter 256. For Duron's enter 64 and for P4 Northwood's enter 512.
After that's done you should notice your programs now have quite a bit more zip and the system is less sluggish because Windows now knows how to use your L2 cache properly.

XP defaults at 200. I saw a big performance boost. Later,BG

just an FYI for everyone else who couldn't find it like me.

Ok, I changed it and we'll see how that goes. Good job man!

So, am I special or something? When I checked it out, mine already said 256. Disappointing really. I was looking forward to a performance boost. LOL.
