All ZABBIX pages are very slow

Should be fixed in https://support.zabbix.com/browse/ZBX-3080, you can test in dev branch.

Quick fix,

Open up jsLoader.php and add the following line AFTER <?php

ob_start('ob_gzhandler');


This requires that your Apache understand the GZIP compression, most of the time this won't be a problem.

This solution dropped the loading of jsLoader.php within acceptable range of 1 second.

This works for me! Thanks!

Apache compression

I would think this is the same as using the apache compression. You can add the following to the httpd.conf file. This is what we had running.
I now also added the ob_start to jsLoader.php but did not notice any difference on top of the apache compression. Should I?
