>It would be very unusual to get good performance with traffic in one direction, but poor in the other. Nevertheless, I have seen some weird problems when switches get hit by power spikes etc. It might be worth rebooting the switch(es). I'd recommend against rebooting any router(s) unless they're internal only, routing between local subnets. In most small businesses routers are only involved with traffic to/from the public Internet.

>BTW these days all switchgear should be gigabit (1000Mbit) or better. If there is any old 100MBit equipment present, anything attached to it has a maximum theoretical throughput of only 12Mbytes/sec (actual throughput usually much less), which is much less than what even low-end servers with mechanical hard drives can sustain these days.

>If you're discussing network speeds, be careful with abbreviations. MBps (with a capital B) usually means Mega Bytes per second. Mbps (with lowercase b) usually means Mega Bits per second. There's a factor of 8 difference. Data throughput is usually discussed in MBps, link speeds in Mbps.

Thanks for the tips. I will pass them on.
