Hi Folks, I'd welcome comment on the following situation, which has arisen since I've (temporarily) changed my home network topology. Previously (machines designated as A, B, C): ADSL---Modem | Hub_1----------------A [at which I sit] | 5 metres | 10 metres| | | 1 metre Hub_2----------B | +------------C 1 metre The above has worked very smoothly. Now, in order to have machine to hand while investigating a hardware (power switch) issue, I have brought it near to machine A, with the resulting topology: ADSL---Modem | Hub_1----------------A [at which I sit] | | 5 metres | +-----------------C | 10 metres| | | | 1 metre Hub_2----------B Now, when I am sitting at A and running certain X apps on C (which have relatively heavy throughput such as raster re-drawing of sections of screen), there is clearly congestion: output from C on A's screen can hangs for a few seconds at quite frequent intervals. But it can also happen from time to time when I'm simmply typing text into C (as now). Not much has changed: the cable to C has been plugged into a different hub, with a different cable (5m instead of 1m). Comments would be welcome! I don't think such a change should have much effect. Best wishes to all, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <ted.harding@nessie.mcc.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 16-May-07 Time: 23:14:22 ------------------------------ XFMail ------------------------------
