How to get a HUGE performance boost on a low-mem dial-up machine:
killall -9 kppp # !!!!!!!!!!!!!!!!!!!!!
On occasion, when out of town, I have to use a ppp connected host with a
paltry 80MB of memory... once again, the performance (due to excessive
swapping) was pathetic -- just switching desktops and getting the windows
redrawn was taking 15-20 seconds.
I checked with 'top' and found that, as usual, kppp was taking a LOT of
memory -- today, it varied between 10M and 35M!!
I figured enough is ENOUGH!... so I killed kppp...
SURPRISE!!! not really... I can now switch between the desktops in about
**ONE** second...
kppp is doing *nothing* other than starting/stopping pppd on this
machine; so *WHY* should it take so much memory...??

Just starting kppp without making a connection, it shows:
9753 pfortin 9 0 7608 7608 6896 S 0.1 9.7 0:02 kppp
OK... the 7608 includes all the libs; BUT....
since this dumb little utility is only starting/stopping pppd, WTF is it
doing eating so much memory... (up to 35MB(!!!!) today...???!!!)
