Test results: CLIENT-1 is having the problems when CLIENT-2 is using all the (100Mbps) bandwidth eg. copying files to MAIL-SRV. If I move CLIENT-1 to CLIENT-3 then almost all the delay is gone. NB.: I have not (yet) tested if the problem also exists when CLIENT-2 generates traffic to MAIL-SRV as opposed to OTHER-SRV (but I am expecting the same problems).
So the link between your 100 Mbps switch and the 1 Gbps switch is saturated by CLIENT-2, so CLIENT-1 is just getting the leftovers?
Since CLIENT-3 doesn't go through that 100 Mbps switch, it obviously doesn't see that issue.
Yes - that's my current "workaround" (perhaps also solution), I'm wondering if the performance is really expected to be _so_ bad when other users are utilizing the LAN. (You seem to indicate that what I am observing is expected and is "just" caused by [un-intended] semi-bad behavior from other users…)
