Nginx - Server dead when received many requests

ae flag

we have a large Woocommerce website hosted on Google VM servers (E2 4vCPU + 32 GB RAM + 100 GB SSD Storage), recently we created a mobile application using flutter and WordPress -Woocommerce- API, but we faced a two issues

  • fetching data is very slow, to load a product maybe it will take more than 5-10 seconds on a HighSpeed Internet connection
  • if the user using the app, the website will take more time to load or down, it seems the server dealing with a single request only at the same time

Environment Details

server NGINX + MySQL + PHP-FPM
PHP 7.4
OS: Centos 8
All tables Engin - InnoDB

we did the following

  • increased PHP.ini memory limit to 128MB
  • increased PHP.ini timeout limit to 3000 sec Linked website with cloudflare. - Installed Cache Plugin W3 Total Cache
  • Increase NGINX MAX Clients to 250

I am looking for a suggestion on how I can allow the to server/MySQL to handle a lot of requests.

1) All PHP 7.x releases are now end of life, so you shouldn't be with 7.4. 2) Similarly, CentOS 8 reached end of life a year ago. 3) For slow responses, did you observe any clear pattern yet? Did they happen under high load or any time? You will need a lot of knowledge on PHP and database, so as to dive deeper to learn where the slow comes from. Usually you need the original developers or an experienced consultant to assist. I don't think it is an easy task that anyone can help over a site like this, where not enough details are yet revealed.

Additional DB information request, please. Post TEXT data on justpaste.it and share the links. From your SSH login root, Text results of: A) SELECT COUNT(*), sum(data_length), sum(index_length), sum(data_free) FROM information_schema.tables; B) SHOW GLOBAL STATUS; after minimum 24 hours UPTIME C) SHOW GLOBAL VARIABLES; D) SHOW FULL PROCESSLIST; E) STATUS; not SHOW STATUS, just STATUS; G) SHOW ENGINE INNODB STATUS; for server workload tuning analysis to provide suggestions to avoid what looks like dead.

Post TEXT data on justpaste.it and share the links. Additional very helpful OS information includes - please, htop 1st page, if available, TERMINATE, top -b -n 1 for most active apps, top -b -n 1 -H for details on your mysql threads memory and cpu usage, ulimit -a for list of limits, iostat -xm 5 3 for IOPS by device & core/cpu count, df -h for Used - Free space by device, df -i for inode info by device, free -h for Used - Free Mem: and Swap:, cat /proc/meminfo includes VMallocUused, for server workload tuning analysis to provide suggestions.

@mohammad If you could post some of the data requested Feb 6, 2023, we would provide suggestions to assist with avoiding a dead server when busy. View profile for contact info. –

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
