Even reading the sio manpage is unclear. All it says is that things are too slow. Steady state I don't get these, just every now and again it happens. No apparent correlation to the time of day, cron jobs running, etc. What I was wondering is if there is a way to, say, double the buffer size. Also, what is the number of overflows mean? Is that bytes? clists? 16byte chunks? The overflow seems to happen just once and it is always a number less than 1000. I'd gladly spend an extra 1-2k of memory to help my poor ppp machine over the humps.
