    In the WHM (9.1.0 / cPanel 9.1.0-R85 / on RHES3) under “software/update apache” the gzip module is listed as “experimental”. Why is this? My understanding is that mod_gzip has been around a long time and is stable – does the “experimental” have something to do with using it with cpanel?

    How risky is it to install this? I’m unable to find anything regarding the stability of this feature w/ cpanel and would appreciate feedback from those using it. I understand the benefits of mod_gzip, but I’m unclear on the downsides when using it w/ cpanel (or why it is listed as experimental). TIA _unfiltered

    Development on it was dropped a couple years ago and to my knowledge it is no longer maintained by anyone so it may/may not work depending on your configuration.

    I have used it before but I ran into some issues with Apache hitting 100% CPU utilization occasionally after installing it so I stopped using it.

    mod_deflate under apache2 is quite nice, I use it on a few other non-cpanel boxen.

    Wonder if/when we'll be able to get it into the cpanel configs for our use?

    Been using mod_gzip for over a year on a redhat 7.3 cpanel server with absolutely no problems. Works fine.

    If I'm not mistaken, mod_gzip is used on the slashdot.org servers. It can't be all too unstable :)

    yeah, it's used by yahoo, google, etc. it saves bandwidth ~60-75%, speeds up page delivery ~300%, reduces server load... which is why i don't understand it being listed as "experimental" in cp - unless it's a cp issue, or bad documentation on behalf of cp (suprise suprise ;-0).

    anyone using it w/ cpanel 9.x?

    ye I have been "experimenting" with it for 3 years on 4 production boxes. It's a good experiment so far :)

    If there is trouble, it will find me
    This is what has scared me away from using it. I have seen quite a few people having issues with it.

    We used it several years ago, but after some user complaints and some research discovered that users were still being accredited with the unzipped bandwidth. We did extensive testing on this comparing page size and byteslogs and saw the byteslogs included the unzipped amounts. Also, you can lose some of its effectiveness if you are tying to zip already zipped php files (ie vbulletin, etc).

    mod_deflate is mod_gzip - it was donated by the old maintainers
