More than 100 concurrent user makes server very slow

jjrjames commented 5 years ago

Hi, I am using ejaberred latest version with jsxc as client for my project. it is taking too much time while connecting more than 100 concurrent users having 2 or 3 tabs.

Can any one help me is there anything i need to change? Thanks in advance

What are your cache-related settings (or all settings, with URL and SECRET anonymized)? What setup are you using? Do you have (anonymized) logs for the XMPP server (related to authentication), xcauth, and Nextcloud (related to JSXC authentication)?

Reasons for slow-down that come to my mind right now:

Caching enabled (cache-storage != none) and high cache-bcrypt-rounds
The first login for each user with ejabberdctl set (setting the shared roster groups is slow, but is only done when things have changed)
Starting each xcauth process from the command line (as was the recommended scenario for xcauth < 2.0) instead of going through the socket interface
Slowness of the Nextcloud server
