Environment:
High traffic video / audio / article site - Similar to a news channel
cPanel Server with Apache Booster Installed
nproc = 64
RAM = 256 Gb
Apache Booster uses Nginx, Varnish & Apache.
Please find a basic to medium level of Performance Tweak to support such sites. This might vary. Always use with Caution.

| 6 | NGINX | nginx.conf | client_max_body_size | Defines the maximum size of client request bodies. Used for handling file uploads. | client_max_body_size 100M; (Increase based on video size) |
| 7 | NGINX | nginx.conf | proxy_buffer_size | Specifies the size of the buffer for proxied server responses. | proxy_buffer_size 128k; (Optimize for large dynamic content) |
| 8 | NGINX | nginx.conf | proxy_buffers | Defines the number and size of buffers for proxying large responses. | proxy_buffers 4 256k; |
| 9 | NGINX | nginx.conf | proxy_read_timeout | Sets the timeout for reading a response from the proxied server. | proxy_read_timeout 300s; (To handle long video streaming) |
