Well, if you're not doing a huge amount of stuff with graphics in firefox or
Gimp, you probably won't need the swap, so I'd turn it off if it's making
Here's the specs of a machine that's running as I type this:
2 Dual core Xeons 5140 @ 2.33GHz
8 gigs of ram
2 intel ethernet cards. It's an IBM x3550 server box.
Currently, I've got 41 people logged in:
sbalneav at sputnik:~$ ps -ef | grep [Mm]etacity | wc
41 449 4090
sbalneav at sputnik:~$ uptime
14:05:32 up 12 days, 16:49, 44 users, load average: 0.38, 0.51, 0.57
All of them are using NBD. I'm using Via E10000 mobos with 1 gig of ram
So, I know the NBD works, at least in my configuration. Now, I've got "dumb"
switches: i.e. non-managed regualar D-Link switches. I wonder if something's
going on with the networking side of things. Do you have Managed switches,
and if so, can you get some stats out of them?
