I am using magento 1.8.1 and it is very slow. I want to optimize this, for that I am using some free module for HTML, CSS and JS minification but its doesn't work.
After using that it create lots of error. I've referred website such like after merge JS, the custom module in front-end is stop working. I've checked lots of tutorial also for gzip compression and enabling Mod_deflect, I've followed all the step like put some code in .htaccess page like
<IfModule mod_deflate.c>
# Compress HTML, CSS, JavaScript, Text, XML and fonts
AddOutputFilterByType DEFLATE application/javascript
AddOutputFilterByType DEFLATE application/rss+xml
AddOutputFilterByType DEFLATE application/vnd.ms-fontobject
AddOutputFilterByType DEFLATE application/x-font
AddOutputFilterByType DEFLATE application/x-font-opentype
AddOutputFilterByType DEFLATE application/x-font-otf
AddOutputFilterByType DEFLATE application/x-font-truetype
AddOutputFilterByType DEFLATE application/x-font-ttf
AddOutputFilterByType DEFLATE application/x-javascript
AddOutputFilterByType DEFLATE application/xhtml+xml
AddOutputFilterByType DEFLATE application/xml
AddOutputFilterByType DEFLATE font/opentype
AddOutputFilterByType DEFLATE font/otf
AddOutputFilterByType DEFLATE font/ttf
AddOutputFilterByType DEFLATE image/svg+xml
AddOutputFilterByType DEFLATE image/x-icon
AddOutputFilterByType DEFLATE text/css
AddOutputFilterByType DEFLATE text/html
AddOutputFilterByType DEFLATE text/javascript
AddOutputFilterByType DEFLATE text/plain
AddOutputFilterByType DEFLATE text/xml

But that also didn't work.

Please help me into this.
Magento has the option to merge css and js files which works for me. I minimise the css and js files I use but I DON'T minimise the standard Magento files (epsecially prototype. I've read that this can break things).
As for compression, it's possible that you can't use the standard htaccess approach. See Compressing js & css files where mod deflate not available for a way around it.
Try to merge CSS and JS byon the admin panel System > Configuration > Developer (Be careful with the JS, the site stop working right in my case).
The thing that change everything for me it's changing the cache module. Magento use a cache module witch use the Zend_Cache library and create a huge numbers of files that makes the site terrible slow. You can easy replace it with this:
Cm_Cache_Backend_File
or even better, magento is prepeared to work with Redis. With this feature the cache goes to RAM instead the File System.
Good luck!
