Re: [Digital BW] PhotoShop CS vs. PhotoShop 7 - some hard data

2003-12-29 by Jack M Kucy

I am stunned by the time your machine needs to start PS-CS.
My laptop Win XP - 2.4GHz, 1GB RAM, with the 3.8GB partition for a 
scratch disk loads the PS-CS in 28 sec.
I have just checked it 3 times, rebooting the machine and starting from 
scratch.
My old station Win2K - 550MHz, 1GB RAM, with the 15GB partition for a 
scratch disk loads the PS-CS long -
say very long for me - 1min 27 sec.
I have not too many plugins, but the usual Andromeda, Genuine Fractals, 
IR and so. I could never thought that the machine
with double processor drags it's feet that much.
--- If I am frustrated by the slow start of the PS-CS... Wow...

The AutoFX Edges plug-in will kill you on boot-up time. I removed it 
from my plug-ins folder in PS CS and put in a dedicated folder only 
to be used when needed just because of the boot-up time it requires.

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
