Making a system faster? That seems a completely counter-intuitive conclusion :-)
A file-system filter is used (IIRC) that compresses/decompresses data at runtime. That would have some overhead and would generally make disk I/O slower. Where it would make things faster is if you had some large files that compressed well - fewer sectors would need to be read/written. But most system binaries (like .exe files and .dlls) do not compress well.

There doesn't seem to be a lot of information or real world testing talking about it. I realize the NTFS version is 3.1 still, but with features like BitLocker in Vista, I'm sure there are some underlying changes. I can't remember where I read 'way back when' that compression sped up / tweaked the system, but any links I can use to document pros/cons would be appreciated.
