Thanks Bruce for that clarification!
I just took a look at a vanilla CSGO server running on linux and
stumbled across this command as it seems to be set to 0 by default. What
would be a recommendation when to enable it (2/4/6/8 Cores)?
Has anybody played around with that on different setups - especially on
linux?
Best regards!

sv_parallel_sendsnapshot controls whether the sending of network data

(when set to one). Doing this on worker threads can reduce how long
it takes to process a frame, if you have sufficient cores.
Using sv_parallel_sendsnapshot 1 doesn't reduce the amount of CPU
used -- in fact it probably slightly increases it. So, if you want to
run as many servers as possible you may want to set it to zero. If
you want to minimize latency then you may need to set it to 1. If you
want to run a 128-tick server on slow CPUs with lots of cores then
you may need this set to 1.
I hope this makes sense.
The main thing is, on Windows servers for a while this setting could
cause packet loss. It should not anymore so it is once again safe to
use.

Could you explain what that command does? I remember in CS:S our
server FPS used to cut in half with that set to 0(55 slot server).
Thanks

This problem was caused by insufficient buffering on the UDP sockets
on Windows. sv_parallel_sendsnapshot 1 caused data to be sent
quickly enough to overrun the buffers, leading to packet loss. This
was fixed with the July 1st update.

Subject: [Csgo_servers] sv_parallel_sendsnapshot 1 = 15% loss
Recently my servers have been experiencing high loss. After
investigating it with the datacentre, they confirmed it not to be a
network issue. As loss was generally associated with network, I was at
first puzzled as to why the server would be receiving loss. After
poking around, I found out that sv_parallel_sendsnapshot 1
<http://csgo-servers.1073505.n5.nabble.com/file/n7306/15%25_loss.png>
was the cause to the 15% loss that everyone was receiving
After setting it to
sv_parallel_sendsnapshot 0
<http://csgo-servers.1073505.n5.nabble.com/file/n7306/Zero_Loss.png>
everything was fine.
There is no problems with the network. The exact moment I switch to
sv_parallel_sendsnapshot 1 the loss starts and the packets I receive
instantly drops to roughly half.
OS: Windows Server 2008
Network: 100 Megabit

Developer's please fix threaded network packets for windows.
