• Debian 11 is approaching its end-of-life (vendor EOL date - August 31, 2026). Plesk Obsidian 18.0.80 will be the last release to support it.
    If you are running Plesk Obsidian on Debian 11, we recommend you upgrade those servers to Debian 12 using our dist-upgrade tool.
  • We plan to deprecate and remove the support for XML RPC protocol versions earlier than 1.6.9.1 in Plesk Obsidian 18.0.82. We strongly recommend that you update all existing integrations using earlier versions of the XML RPC protocol to comply with the version 1.6.9.1 specification.

Question HIGH RAM USAGE BY MYSQL USER

mmv10

New Pleskian
Hi guys,

I'm noob in plesk and I need your advice.

I've got a dedicated VM with 3vCPU and 6GB RAM, and I think the RAM usage by mysql is very high.
I've got a web site (between 20 or 30 users simultaneously connected) and the server behaviour is the following:
13671-2e79c63ed677aa3e620f2930a2571729.jpg


4.7 GB usage of 5.8GB, mysql user has the 64%... is this behaviour normal in plesk onyx??


In my my.cnf I've made the following configuration:

max_allowed_packet=500M
innodb_buffer_pool_size=3072M
query_cache_size=0
query_cache_type=0
query_cache_limit=4M
join_buffer_size=3M
thread_cache_size=4
table_open_cache=1000
innodb_file_per_table=1
innodb_log_file_size=384M
innodb_buffer_pool_instances=4
slow_query_log=1
long_query_time=3
slow_query_log_file=/var/log/mariadb/mysql-slow.log

For such configuration, I used the mysqltuner.pl script.

Thanks in advance!

Regards.
