Hello.
I've just installed FreeBSD 2.2.7 on my 486 home 'puter and got
Xwindows configured and running and was quite happy with its
performance until I had it make a ppp connection to my ISP. Once
the modem connection was up, *everything* s l o w e d down. What's
weird about it is that if I move the mouse, things speed up. If I
just let the mouse sit, performance drags heavily. I checked out
what was going on with 'top' and found that while the mouse is at
rest, nearly 50% of the CPU is used in 'interrupt' It's usually at
just a smidge above 0.0% interrupt when the modem isn't connected.
Weird, no? Think it has something to do with the fact that both
devices (modem & mouse) are on the machines 2 serial ports.
Here's how the ports are set.
Mouse: Serial (Microsoft) COM1
Modem: External 56k COM2
I tried running the mouse both through moused as well as letting X
talk to it straight through the serial port (cuaa1). No real
difference in performance, and still the symptoms continue.
Does anyone have an idea about how I can go about getting this
fixed? On my 486, performance is a scarce commodity, and this type
of loss makes the machine virtually unusable without a third arm to
move the mouse about... The sad thing is that until this key point,
X has out-performed and out-featured Windoze95 which I have
installed on the other half of the drive.
Can anyone help? Pretty Please?
