>From personal experience one possibility is that serial interrupts are not being serviced quickly enough, which can be a big problem with older slower hardware. If too many interrupts are missed then you get serial buffer overflows, dropped packets and delays as TCP/IP tries to recover. There are two things you could try, if this is the case. One is to use irqtune from the hwtools package to boost the serial interrupt priority. The documentation explains what is going on. The other thing, if you have an IDE controller, is to unmask interrupts using 'hdparm -u1'. There are dire warnings attached to that option, so proceed with care. Frank
