Mod Gzip Hosts
When I recently tested an H Sphere host, my bandwidth ran much higher than usual, so I was thinking that maybe that was because they weren't using mod_gzip and my previous host did. Or maybe bandwidth is not very accurate with H Sphere?
Don't most hosts use mod_gzip to save on bandwidth? Are there any disadvantages to using mod_gzip, such as slow page loading?

to check whether mod_gzip is installed on your web server, go to http://www.leknor.com/code/gzipped.php . Even with mod_gzip installed, unlike CPanel, HSphere does record http data transfer correctly (compared to webalizer/analog).
The advantages of using mod_gzip far exceed any disadvantages that it may bring. So yea, most hosts that I know will have mod_gzip installed, although it's a benefit to the clients more than to the hosts themselves, since the host can actually make money off bandwith usage too

The only disadvantage I can think of would be a little higher server load and a little slower page views for the user.....however, if the server spends less time transmitting the data and the client less time downloading, it is debateable if there is a negative impact.

For a 56KB of file, I will be surprised if mod_gzip takes more than 0.5 second to compress it. The compressed file will, say, be around 14KB. If your user is using a dialup, it will take them around 7 seconds to download the uncompressed file and only 2 seconds to download the compressed file. The end result (even if mod_gzip does take 0.5 seconds to compress the file), your user will experience a much faster download rate from your webserver. I would be surprised to hear if there are host with users complaining about slower response after mod_gzip is installed on the web servers.

I will agree with you FHDave. In theory....it would add/delay the transmission of the packets to the client, thus increasing server load. However, as your post implies, there is a greater good provided, faster downloads, especially for dialup users and lower bandwidth...which is especially good for us hosts.

If you're on a fast connection (Cable, DSL), you probably won't see any difference at all in download times, unless you are viewing very large pages. However, people on dialup modems should see a lot of improvement.
gzip pros and cons:
pro:
- less bandwidth costs
- faster loading pages
cons:
- slightly more cpu usage.. not very noticeable

1) What is GZIP? The GZIP zips up the content of your website and sent to you visitor. Your visitor browser then unzips and see the content. This process is transparent to your visitors. For an example, my index.html is 100KB in size. But after GZIP, it is only 30KB. My visitor only download 30KB thus decreasing the bandwidth consumption.

2) My site also pulls about 200 active members, but we do not have much of attachments. They are accidental so to say.
Without gzip we pull 2gb on 500+ threads and 5000+ posts.
With gzip we make 500 to 750 mb traffic.

3) My VB is hosted at xxxxxxx, and I used to have load of error 408/409. Things finally went fine when I enabled the GZIP option, and the daily bandwidth utilization dropped to less than half.

4) (eva2000) if you have php compiled with zlib support you can enable gzip in vB admin panel set it at no higher than level 1 and that will compress and speed up loading of all vB php pages
if you don't have zlib support compiled into PHP then you can't use it but you can try installing mod_gzip which will compress all server pages not just vB's php pages
http://www.vbulletin.com/forum/showt...highlight=gzip
it will compress your pages' sizes and make loading the pages faster and reduce your bandwidth consumption/costs

5) I like the effect of turning VB GZIP on, in terms of less bandwidth and effectively much faster responses as my server is a lot of IP hops away from my users...

Soemone said that it benefits clients more, actually it benefits hosts more, because 99% of clients don't use anywhere near their full data transfer without mod_gzip enabled - so if the host can shrink that amount even more then they save money because the site uses less of it's free x-fer.
