hello,i am a linux system administrator ,and i have problem now,the nginx as picture server,the bandwidth is higher than apache in the same condition.For example,established connections is 3000,apache's bandwidth is about 4MB,but the nginx is about 7MB,i am sure the two servers run the same services,and in the same datacenter .what should i do,maybe i should modify config files,but i don't know what should i do.Could you help me,thanks!

Does you mean that with 3000 R/s you deliver 4MB with Apache and 7MB with nginx? Are you sure that the requests are the same, the data which are deliverd and the r/s also? BR Aleks

Also, look at gzip compression, you might want to have to turn that on in nginx (in case you have it in apache). I don't see any other way to have such a big difference without 1. difference with compression 2. difference with request ammount 3. difference with request caching, mod_expires (as mentioned before by almir) Lp

I am sure,others have asked me the same question.So,I think that the problem is in config file. 2008/8/14 Aleksandar Lazic <al-nginx@none.at>

I really don't see what difference the web server would make here. You should do some research and compare individual requests, rather than talking about vague large numbers, especially when you cannot guarantee that *exactly* the same requests were made to both servers. Right now, there are too many variables to know what's really going on.

Maybe apache handled only 4MBps of traffic and nginx can handle much more?

I use httpwatch to test a same image in apache and nginx.The result is
size
apache 457
nginx 699
I think that is where the question arises.

I'm not sure if apache compresses images, but it is possible. And nginx does not compresses content by default. Maybe there's the diffrence.

Do the test.I find use gzip is the same as not in nginx. 2008/8/15 iDEV d. o. o. <info@idev.si>

What is this size ? Size of the image or size of image + HTTP header size ? What the size of the image itself ?

I am not very sure,the image is 27.88KB itself. 2008/8/15 Igor Sysoev <is@rambler-co.ru>

Then I do not understand what 457 and 699 mean.

I can't imagine a system admin would take a week to hypothesize about config files when they could just dump the transactions to determine what is going on. Chaz

Until you say what is 457 and 699 exactly the discussion will be
helpless.
Try tcpdump as it was suggested. Try debug log.

By the way,I want to ask a question,is nginx as image server is better than apache?If you do test,plase tell me! 2008/8/15 Igor Sysoev <is@rambler-co.ru>
on 15.08.2008 09:49
Of course, i have tested . There are many examples of the Internet . I think now is the era of nginx .

what on earth does better mean? thats an awfully general question.
