In Windows, perhaps it was 576. I'm not sure, but used several free
utilities to make that determination after sending packets at various
sizes and I don't know why it should be different since it is the same
ISP. I think someone could use EasyMTI (which is free) in Windows on the
and use the same settings. That seems to make sense to me, and at least
with Linux, you get to set those variables, whereas in Windows you have to
tweak the registry, which can always be hazardous [g].. I just use the
Linux (type unix) environment, as if I was using a shell account for
super-fast programs like lynx and great old pine. When I looked at
/sbin/ifcong (during connection), it didn't show any errors, so the packet
size is probably right then. I may play with it to see if thruput changes
any, but believe it is at least close. My ISP doesn't support Linux at
all, like many of them - so I can't ask them anything [g].. Thanks Mikkel.
