SubjectRe: My memory is rusty
Rusty .....that's a term I haven't heard to explain degraded
performance...but anyways...:)....as a Computer Technician it seems that I
see this kind of situation almost on a daily basis....I don't want to
sound like I am talking down to you, I'm not...but many
times...performance degration is usually causes of end users' not
performing routine maintenance on their respective systems...it seems that
many users think that they just go buy a system and voila, it runs
perfectly forever....if we were to treat our vehicles in the same fashion,
automakers would control the world...(don't they already?!) Regarding your
statement that when you boot into your kernel, performance goes bad, it's
probably just because you are trying to run programs that are "memory
hogs" and of course, the way to solve that is to increase your RAM and
processor power. I know how it is to run at 16 M with a Pentium
120....it's not fun...and it would be different if only coders who write
programs wouldn't make them for the 64 M machines that they happen to
own...I see that all the time! I currently run 80 M with a 120 MHz
processor....I still don't like memory hogs...it's annoying...
