I found that my computer has a TPM module to work with BitLocker but now I'm trying to see if it may reduce my system performance...

There's my spec:

Intel Core 2 Duo 3.0Ghz (VT-x)
2GB of DDR2-800 RAM (upgrading to 4GB soon)
160GB Western Digital 7200RPM

I want the best performance 'cause I'm a .NET and Web developper...

I believe it would with a Core 2 Duo, although I have not tested it myself (I have never used BitLocker, even though I have TPM chips in some of my harware), but it does not (so much?) with the latest Intel and AMD chips, which have support for hardware AES encoding/decoding.

If it would with a Core 2, then it should with the latest AMD/ Intel chips. It wouldn't be noticable really, but it'd still be there. – cutrightjm Apr 10 '12 at 3:33
@ekaj: I do not understand what youare talking about, but the AES instruction set makes a lot of difference.… – paradroid Apr 10 '12 at 4:25

Normally yes. Just upgrade the RAM to 1333 and you are almost done. 4 GB as you will rarely find 2 GB 800.

The slowness is not very noticeable. As you see, it's the same as you compare Windows 7 basic to Windows 7 Ultimate. The slowness is noticeable on low hardware but rarely makes a difference on new hardware PCs. Did that make sense?
