Enabling output buffering and zlib / how to check performance?

Hello, should i enable output buffering and zlib compression in PHP configuration editor to increase performance?

In global php.ini i have:

php -v

im using SuPHP

When testing hosted website if it do "mod_gzip, mod_deflate, or any server-side language that does content compression", it returns that site is compressed. (http://www.whatsmyip.org/http-compression-test/)

So i need to enable zlib and outputbuffering (both?)? Please before i do that please advice on how to check performance result before/after? Thank you

 

You should be able to turn both options to "On" and then you can use phpinfo() to ensure that it is active.

You could use an Apache load test to see the performance difference with the settings turned off vs on.
