Hi John,
Thanks for the reply.
The host i'm with right now is linode.com and they are great, except that i
see performance drop when i hit around 28 players+. I think i'm shy by
about 200-300mhz to pull a 32player server off smoothly.
I have been in contact with them regarding CPU and the fastest servers they
have right now is what i'm on now:
Intel(R) Xeon(R) CPU L5420 @ 2.50GHz
It's a bit surprising that this is the fastest that they have.
Harpertown is a tad long in the tooth right now and lacks EPT, so you're
right about these CPUs being slow. Game servers perform much better at
the same clock speed on Nehalem and better (in many cases, 30%+ better)
and the EPT support in Nehalem+ processors speeds up virtualization. It
might be worth checking around for a host that uses Nehalem+ and/or that
can offer Windows.
I have 4 cores to work with but with SRCDS not being multithreaded it
doesn't work out in my favor. The only OS i have available are *nix based.
What threading/parallel processing options in OB are their? I looked all
over and couldn't find anything to try out to potentially help me out.
Try "-threads 3" or "-threads 1" on the command line, and try different
values for these cvars:
host_thread_mode (though I'm not sure that this applies to servers)
net_queued_packet_thread
sv_parallel_packentities
sv_parallel_sendsnapshot
Sometimes reducing thread usage or turning off the parallel options
seems to speed things up, surprisingly.
I'm not too sure about PV-on-HVM drivers, i will have to look into that.
If your host is restricting you to Linux only, it's likely that you are
on a straight PV setup, in which case you are set for this already (you
won't need PV-on-HVM).
