Hi, Eran
somaxconn by default is too small
if you have Linux you should encrease:
somaxconn (try 4000 or more), tw_buckets and backlog in /etc/sysctl.conf (don’t forget to do #sysctl -p /etc/sysctl.conf )
nofile and nproc in /etc/security/limits.conf for user which start nginx (read about ulimit)
in nginx config you may try use:
listen 80 default backlog=4000(or more) sndbuf=32k rcvbuf=8k deferred;

for freebsd do netstat -Lan, check queue to port 80 and change same parameters

I see that nginx has problems with spawn-cgi or php-fpm, it is not stable / reliable solution – 502 error.

So, is there a solution to it?

——————–

Can I run apache with MaxClients set to small number and solve the memory issue of apache?

After reading for hourssss in forums , I can’t decide what to use, apache or nginx ?

It is for a drupal + vps .

Thanks

I’ve just completed a set of preliminary benchmarking test with Magento and Wordpress.

Magento has proved itself as incapable of performing steadily under high loads. I believe it is some sort of file-cache locking issue because with concurrency=1 it’s performance was flawless.

Wordpress results are on par with results of “Custom application frontpage” benchmark from this article, only scaled down with a factor of around 0.25 (75% the performance of “Custom application frontpage”). Will publish complete results soon.

Yes, I am thinking about that, but a standard dataset (database content) must also be available so that test becomes realy repeatable. I found that Magento has such a starting dataset.

Can someone recommend anything else? Thanks.

It would be interesting to test typical PHP application, like Wordpress for example.

[...] We all know that Apache is a great software and it cannot be replaced every time. Also, Apache shown great performance serving dynamic php content whether it’s running mod_php or fastcgi. Boštjan Škufca made an excellent comparison between Apache + mod_php and Nginx + php-fpm. [...]

As you can notice above, the HelloWorld.php gives better results with Apache than with NginX. I repeat, this is a synthetic test, which only proves that proxying requests to another server (in this case php-fpm) creates some latency and/or overhead.

The answer to you question about Nginx in front and Apache behind: if you are only going to forward ALL the requests to Apache, then you will have static file serving performance penalty. If you serve static files with NginX, then it really does not matter that much which application server is in the back, Apache or php-fpm. If you are familiar with Apache and it does not seem too much hassle to configure, go with it then. Single tool that you are familiar with can always serve you better than 100 different tools you briefly know. And you can always switch to php-fpm later. But, php-fpm is very easy to set up – apply patch, compile php, modify config file and voila.

Sorry, I forgot that you DID in fact use a op-cacher: eaccelerator. Disregard my last paragraph.
