Secondlevel Datacache(L2Cache) is very important for the performance of CPU. Normally winXP should recognize your CPU and the value of the L2Cache. However, sometimes XP can't do this. So you must tweak it by yourself to improve the performance:
1. run "regedit";
2. goto "[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Memory Management\SecondLevelDataCache";
3. modify its value by decimalism:
AMD Duron: 64(kb);
CeleronA/celeron2:128;
PII mobile/PIII E(EB)/P4/AMD K6-3/AMD THUNDERBird/Cyrix III:256;
AMD K6-2/PII/PIII katmai/AMD Athlon:512;
PII Xeon/PIII Xeon:1024;
4. reboot.
Now, see your XP work better than ever.
