Slow performance with user function overview pages (SLES 12)

Software Support

Hi there,

after installing OJS on a new server, I am experiencing a problem with pages like /index.php/index/admin and /index.php/journalName/manager: The pages load very slow (about one minute).

  • the sum of all database query times is about 6 ms
  • no CPU peak is shown in server monitoring
  • top shows that httpd and mysqld consume up to 1637948 KiB in virtual memory, which would be about 1677 MB

I think this is quite odd, as those pages contain only links and shouldn’t really take up that much.
Is there anything special about those pages?
Did anyone have the same issue using OJS on SLES 12 with MariaDB?

Thanks!

Hi @ojsbsb,

I suspect that your server is firewalled from accessing the PKP website. On both of those pages, OJS attempts to fetch the latest version number of OJS from the PKP website, to display a warning message if the installation is out of date.

Thanks @asmecher, I didn’t think of that. Is there any way to deactivate this? The server is not connected to the internet and will be used for demonstration and training. So we don’t really need update notifications there, but a good performance.

Hi @ojsbsb,

Find the general section in your config.inc.php configuration file and add:

 show_upgrade_warning = Off
