[K12OSN] Making thin clients "faster"

You did not mention how many concurrent connections you have max at any
given time to your server. You should at least bump up your ram in server
to 2G as ram is pretty cheap. With just web browsing any TC should be
adequate. Only video running will of course kill your bandwidth,especially
if you are only using 100MB backbone. A "cheap" upgrade would be to buy
you a couple Trendnet 26-port unmanaged switches that have the two GIGE
uplinks to get your server to the TC 'room' to feed to the TC's if you are
only running 100MB for example. They can be had for about $100 per. Make
sure your server does have a GIGE nic on the TC's feeding side(eth0) ,or
else the GIGE switch upgrade would be mute. You may considering
downloading jperf to measure what kind of throughput you are getting from
server to > TC. I made an rpm of jperf which makes it a very simple setup.
You simply start jperf in server mode on the server console,go to one of
the TC's and run jperf in client mode. It will be a good tool for realtime
bandwidth 'watching'. You can download the jperf rpm here,which should
work on any current version of k12ltsp,


Take Care,
