im wonder....wat does it takes to calculate?
Well, based on the explanations,

Creates a VIRTUAL EXT2 filesystem inside the stock RFS filesystem on the internal SD card, with a 4KB block size. This means that this lag fix creates a buffer between the real filesystem and the android system. This buffer should reduce the amount of disk I/O required for all operations by utilizing EXT2 buffering, as well as not writing file access times to disk, etc.

So, if u can speed up the read & writes, yr system will perform better.
For a PC in Windows OS, say Vista or XP or 7, the more RAM u have, the faster the OS runs as the OS will use available RAM to cache yr reads and writes instead of writing directly to HDD.
Hope this explains.
My 5cents worth of explaining "how to increase read/write performance...."
