The server become slow when approximate 1000 users access the site at the same time, and later the server not responding at all (blank page).
I did the following tasks:
Production mode enable
Full cache enable
Compile the code (setup:di:compile)
Deploy static content (setup:static-content:deploy)
Merge CSS Files
Minify CSS Files
Apache GZIP compression
Enable use flat catalog category
I want to know what another thing can I do to improve the server performance and avoid the server crash?
Thank you very much.
