Hi,
I have a small home-net running one server (SUSE 10.0) and at present two (SUSE 10.0, 9.1) clients. The server (10/100MBit net-card) has cups/nfs/squid and does dial-in through a 56k modem. One of my clients has 10Mbit, other one has 10/100 network-card; one of my cables is cat 5, 100Mbit. I have a Surecom hub (10Mbit) connec- ting the comps, working in normal mode (not cascade). I don't mind to ride 10Mbit, because with that hub there is no higher speed, but I wonder which component (hw/sw) I should check to find the reason(s) causing package collisions in the network. The hub itself doesn't show them or at least I don't see signals there on its LED, but 'ifconfig' told me about existing collisions. I have no blackouts and otherwise everything seems to work very well, so I'm really surprised to see collisions there. Hmmm. But maybe that is, why I can't reach the upper limit of 10Mbit (1,25Mbyte/s -> 1280Kbyte/s) and I'm operating constantly at about 1050Kbyte/s only?!
Generally speaking is the highest available speed hardware/firm depen- dent, so better to look for another, preferably more expensive hub/switch or 10Mbit is almost the same for all 10Mbit stuff?
Thanks a lot, Pelibali
You will always see some kind of collisions... Minor ones are a given. And the differences in top speed is also a given. You will lose some for overhead, and these speeds are in theory. Just like if you had a 10/100 switch...you never get 100 thru put. Get rid of your 10Mbit hubs and get gigabit switches and cards. They are cheaper nowadays... You can get a 5 port for maybe $50. and cards for $15. US (a switch doesn't share the bandwidth as a hub does.) cat5 cables will work. -- Thanks, George "...Linux, MS-DOS, and Windows XP" (also known as the Good, the Bad, and the Ugly)
