Optimize WebServer Performance

Optimize WebServer Performance

WebServer performance can be improved by compressing static web files and reducing the network chattiness between webserver and client system.

_Below are the configuration steps for IHS webserver to enable web compression (to compress web static files) and content caching (to cache static files at client system and reduce network chattiness between webserver and client system)

####Files affected: httpd.conf##############################

Enable required libraries by uncommenting or adding lines to httpd.conf

LoadModule headers_module modules/mod_headers.so

LoadModule deflate_module modules/mod_deflate.so

LoadModule expires_module modules/mod_expires.so

_Enable Web Compression (for files with MIME type: text/html text/plain text/xml text/css text/javascript application/x-javascript)
