24 Hi Dale,
25 That seems way high to me but I cannot do a real comparison here as
26 I haven't had a 32-bit X86 machine in 4-5 years. My current box is
27 tied up running 3 copies of Windows at the moment and is using pretty
28 much 12GB at the moment so I'd have to reboot to take any reading.
29 However I seem to remember only 350MB being used right at the point of
30 logging into KDE, but I could be wrong about that.
31
32 Maybe post a few numbers:
33
34 1) What is used when you first start KDE
35 2) The additions for a few common apps.
36
37 I'd be happy to compare mine to yours later today.

39 - Mark
