I'm using ubuntu apache and my site is created from php, jquery and necessary html & css.
Already I have done lot of things for improve performance. All the js calls after css and first fold no js & css blocking and minimizing css js and sprite images everything is already done.
Now my need is I have to reduce the server initial response time. and
Also sprite image is taking 1 sec to load for just 90kb file.
Can anyone help me to fix these issues.
Thank you in advance.
