Currently I'm using Centos 6.5 and current kernel is 2.6.32.
CPU Xeon 8 threads <--- I mean 8 threads not core ) sry
16Gb ram

I'm aware that the usage of CPU is like locked at 10% and causing server lag somtimes when there are more resources on server that have not been use. So I wonder if there a optimized version to run srcds at maximum possible?

On https://www.kernel.org/pub/linux/kernel/v4.x/ I see the latest version is 4.x . any one using ? Please help.
Thanks for reading.

8 cores 16 threads? that sounds pretty sweeeet

or just 4 core 8 threads?

Is there even a 4-core Xeon, the lowest I have seen are 6-core Xeons.

paste result of this command here pls.

grep -E '^model name|^cpu MHz' /proc/cpuinfo

Centos is usually really really late in getting the updates out. I would recommend Gentoo, or Ubuntu if you want to test the latest kernel. Debian would be another good choice.

In case, you wanna keep Centos distro. You can always build your own kernel according to your needs. Last I ran CSGO server was on Gentoo 3.2, and it worked really well.

I wonder if this is a CPU problems?

hello ,

It seems not all of your cpu's working on max performance. Swap memory disabled? If not disable it first with command swapoff -a

and than try this;
for CPUFREQ in /sys/devices/system/cpu/cpu*/cpufreq/scaling_governor; do [ -f $CPUFREQ ] || continue; echo -n performance > $CPUFREQ; done

Check cpu speed again with this;
grep -E '^model name|^cpu MHz' /proc/cpuinfo

For last check the CONGIF_HZ. 1000 hz must be enabled on your kernel. Command to check that;
cat /boot/config-`uname -r` | grep HZ

This is on my engine;

[root@xxxxx~]# cat /boot/config-`uname -r` | grep HZ
CONFIG_NO_HZ=y
# CONFIG_HZ_100 is not set
# CONFIG_HZ_250 is not set
# CONFIG_HZ_300 is not set
CONFIG_HZ_1000=y
CONFIG_HZ=1000
CONFIG_MACHZ_WDT=m

CPU = As you can see all of my cpu;s running on max speed.
