For the record, this seems to be working. I rewrote it to work like
this, and I was able to pump it up to 64 clients again (me
broadcasting to the remote server from my own computer, and then
starting 64 clients on my own computer) but CPU and memory usage were
much better. CPU was standing around 1.5% and memory around 3.6%. (I
know these could still be considered SORT OF high, but this is
actually a vserver where both of these resources are quite limited --
only 480 MB of the real server's memory.)
However, once all the clients disconnect, the memory doesn't seem to
go back down to the expected level. Any ideas on where I should start
looking to solve this?
