[K12OSN] Some trouble with flash apps

[Grodeon, Steve R]

I have tried many of your suggestions, and just to verify, my server is hooked into a gigabit port in our switch and I am 100% sure the server is running gigabit.  Dmesg | grep Mbps reported 1000 Mbps link.  When we play flash games on 2 or 3 computers while having a 4th run some network monitoring software, I can see the network utilization jump to the roof, while the cpu usage and RAM are fairly low.  We found that 3 playing at once was completely unusable for one person.  I haven't tried running them at lower resolutions as somebody had suggested, but i sure thought it could handle more than 2 thin clients.  We did try a pretty large variety of games and they all had similair problems.

And I don't seem to have any trouble with anything other than flash games, I have tested many different apps that worked seemingly flawlessly, although none were real video intensive.  If it helps, I tried switching to IceWM instead of Gnome and it seemed to help a little bit, but not enough to make a real difference here.

Yes...the model is right  SR24G2....it is a 26 port switch....24 of them
are 100baseT and 2 of them are gigabit...since it's integrated in the same
switch....you come out of the server from the gigabit card to a gigabit
port and then feed the 100baseT side.  I have several SR24G2's on my
network and they work like a charm.  The price is VERY reasonable.  Flash
will cause lots of issues with your CPU, but it shouldn't be as slow as
you've described.  I'm able to have my entire lab on Flash web sites and
it's acceptable.  You can do some experiments to see where the bottleneck
is.  One idea is to hook your clients directly into the gigabit
switch....make sure they negotiate down to 100 base T though...some
switches won't do that.
