asp.net - How to reduce total waiting time of a web page? -

-

i working on website. of pages on website rendering slow, taking arround 16-20 seconds.

i searched on internet optimize web pages.

everyone says reduce size of web-page or bunch static contents (that is, javascript , css) in 1 file reduce number of http requests server while downloading contents.

but have problems regarding approach:

  1. the source code massive, , dont know impact of merging javascript , css file 1 file (which functionality affected javascript clashes?)
  2. the maximum time waiting time page (around 14 seconds), , have tested total responce time of database server , other processes @ local end, minimal of around 1 second.

also, have tested page staging server, there it's working fine 2-3 seconds of downloading time only, @ production server it's taking arround 16 seconds.

  1. if it's problem of server, page on staging server working fine not @ production server
    1. what code optimzation minimal code changes be?

everyone says reduce size of web-page or bunch static contents (that is, javascript , css) in 1 file reduce number of http requests server while downloading contents.

this won't in situation, slowness in page itself, not download , parsing of javascript code , css.

also, have tested page staging server, there it's working fine 2-3 seconds of downloading time only, @ production server it's taking arround 16 seconds.

figure out what's different between them. clearly, have misconfigured production server in way. if html, css or js it'd show on both servers.
