BF4 on 4 core managed VDS.

[barhund]

Yeah, but even with multi-core on it was topping out at around 27.5% of the four available cores.

How much was it using with single core? I'd guess 25% or so? If so, it'd make sense that you're not seeing a performance degrade yet as it's not needing that much more power for normal conditions, as 27% would be it consuming a bit over a core, so it's not being strained enough to notice a degrade. I'd keep it on as you will likely notice a degrade of performance in any maps/other conditions that cause an increased need for processor power.

It's been full all day with it limited to single core... So when i get home i will get a chance to see how its doing. The weird thing is that with it on multicore on the water maps it would be clearly suffering from overload above a certain number of players. Yet even under those conditions it wouldnt start utilizing more cpu power.

[barhund]

For reference... Right now with 44 people in the server its using 21.27% with an empty l4d2 server up as well.

[barhund]

I'm not sure what is causing the difference in CPU usage anymore. Tonight with 46 (and multi off) It was running at ~28% cpu usage and rubberbanding...

My point was that even with multi-core on it doesn't seem to use any more resources making me wonder if I'm missing something when enabling it. Does the VDS need to be restarted maybe?

[Edge100x]

The multi-core option would not require a reboot of the VDS, just of the game server. I haven't witnessed it helping performance yet, though.

[barhund]

Based on the cpu usage, I don't think it's functioning. But then, I can't see the backend, and what cores are being used by what processes.

[soja]

In BF3 I think it was only known to help lower speed cores perform better. When you have fast cores(which most NFO VDS's do now) it makes little/no difference. Even with the multi-core option the main worker thread is still just 1 thread.

[barhund]

So... Any idea why the play-now traffic seems to not be working? I had found that reseting my server guid for some reason gets me play-now traffic but even that doesn't seem to be helping.

[Edge100x]

I have not heard information on that. One way to investigate would be to use the option and see what server BL puts you into, then going through and copying that server's settings to see if you start getting more players.

[barhund]

but up until recently my server was jam packed full with a waiting list to get in... I didn't change anything. And yet, now nothing. I'll get joiners but it doesn't seem to be getting any play-now traffic. It's just weird.

[barhund]

Just an update... while i was seeding this morning I noticed an EA tester join, and then I started getting play now traffic seems to be working again.
