[Spce-user] Fwd: Re: swap

[Alex Lutay]

Dear fry,

You have small amount of RAM 2Gb, while ngcp-panel
(catalyst PERL-based WEB application) loves memory a lot.
BTW, pull requests to improve ngcp-panel memory usage are welcome!

NGCP configured for high performance on PRO/Carrier customer by default,
so it has 10 ngcp-panel fastcgi processes by default (see config.yml):
  www_admin->fastcgi_workers=10
  www_csc->fastcgi_workers=10
I would recommend you decrease it till 2-3. It should fix your problem.

JFYI, by default 50% of RAM is passed to MySQL for InnoDB buffer pool,
you can also decrease this value (which is not recommended for 
production usage).

Also, you can use the script /usr/sbin/ngcp-toggle-performance-config
which helps you decrease performance options on lowest level if you have 
small amount of RAM (it is recommended for test systems only, like VMs 
and/or Cloud based installations):
> root at spce:/etc/ngcp-config# /usr/sbin/ngcp-toggle-performance-config

Also you can check the script content to tune the system yourself,
to decrease resource usage on unnecessary for you parts.

I hope it has helped you a bit.
