My tiny XP go fast

HI people, at the end i decided to use Nlite to install in one of the Aone of the shop windows Xp.

I take a Windows Xp Home and use Nlite to do a fast version configuration.
I install this version , in fat32 , disabled D2D , disabled prefetch and system restore (not installed yet).

In a pc with 512 mb of ram the system go very very very fast. i'm impressed by this performance. I think it's a very nice and good solution for this pc.
The space used on the disk is 1,33 gb !

 

I've nlited my XP too with prefetch, system restore and D2D disabled. Sometimes XP stalls a little bit when writing to SSD. Overall speed is good.

 

The assurd things is that i install it on a 1gb system and have a little bit stall. On a 512mb ram it doesn't stall, never!.

The difference is that in the 1gb i do the installation, in the 512mb i install with norton ghost and a clone of the other system.

Then i redo the load of the Image of the system with 1gb , over the same system with 1gb and go faster. I'm not shure because it's happened
