When i have no visitors my website loads fastly. However, when visitors came my website speed decreases significantly. When i send 100 user request for a minute, my server crashes. Is server crash normal for 100 users at the same time? Do you have any suggestion? Is there a logged-in cache plugin for buddypress? Comet Cache Pro claims that they have logged-in caching compatible with buddypress? Do you suggest Comet Cache Pro? Do you have general suggestions apart from below optimizations?
My servers feautures and optimizations that applied
8 GB VPS 4 CORE processor
PHP Fpm 7.2.11
Redis Object Cache
Fast Velocity Minify
I don’t think your hardware is your bottleneck. Which program are you using 100 request simultaneously?
Most probably one of the plugin or the active theme is not properly using queries/resources.
Is your mysql database crashing? Try to analyze the logs, that will give you some lead.
Also, I don’t use Comet Cache so I am unable to recommend. In my view, Redis Object cache should be more than enough.
I am using loadimpact.com and Webserver Stress tool 8 software. Both of them handles approximately 100-130 users at the same time. I installed query monitor plugin to monitor queries. Queries are normal but there are lots of unnecessary queries from WordPress core like blog queries. My site is not a blog site. How can i eliminate unnecessary queries? Should i change the autoload column “no” in wp-options table? How about Plugin Organizer plugin? (They claim that it gives control to arrange which plugins will work in specific page)
I won’t suggest going for temporary fixes.
Query monitor only logs query for the current page. When you run the test you should audit your webserver log as well as your database server log for possible causes and try to fix them.
