Hello,

I encounter a high CPU usage on my dedicated server. Only mailcow is installed on it.

Here is specs of the server: Intel Xeon W3520 4c/8t 2,66GHz 16Go DDR3 ECC 1333 MHz SoftRaid 2×2To

I have multiple mysqld process, but more importantly one always at 50% CPU minimum. Can be up to 112-120% sometimes.
Also proxymap with ₃₀% CPU usage.

Is all this normal ? I wonder. My server had yesterday a cooling CPU issue witch needed an intervention by the datacenter team.

Here is a screen of HTOP command.

Can you please hel me ?

As far as I’ve seen this was now solved in the Telegram chat, right?

To summarize and copy messages from @Thomas2500, in case someone stumbles over this discussion:

Try increasing its cache, you do have enough ressources for more MySQL Memory usage
The configuration is located in data/conf/mysql
After changing the file you can restart Mailcow using docker-compose restart service-mailcow
Override the following settings:
innodb_buffer_pool_size = 64M
tmp_table_size = 32M
read_buffer_size = 256K
sort_buffer_size = 2M

I’m marking this discussion now as solved. Feel free to report back.
