 RewriteEngine On
 RewriteRule ^/fcke.*    -       [L]
 RewriteRule !\.(txt|html|gif|css|js|jpg|jpeg|cgi|png|htc|swf|flv|jar|ico|xml|gz|bz2)$ /home/mydomain/public_html/index.php

Cherokee+FastCGI PHP and Memory Leak

Today, I try cherokee 0.98.1 + PHP 5.2.8 FastCGI on my production website (350k daily pageview).

Unfortunetly this configuration seems to have memory leak. After 4 hours, the cherokee-worker process use 50MB RES and 407MB VIRT (from 'top' display).

We used nginx and the same php-cgi binary before.  Nginx seems to have constant memory usage over weeks.

We just to try and compare between cherokee and nginx. Both have good performance but cherokee still have buggy memory management.

This is result of 'cherokee -i':

Compilation
 Version: 0.98.1
 Compiled on: Feb  2 2009 10:15:41
 Arguments to configure:  '--prefix=/opt/cherokee' '--disable-ipv6' '--without-mysql'

It sounds like a show-stopping bug to me.
I'm checking it out right away.

Thanks a million for reporting Ihsan!

never believe a mod_rewrite rule that lists everything by hand like that

That would work, indeed.

However, if you are looking for for performance, the server would be  
slightly faster if you added an extension rule with all those  
extension and set it to use the "Static content" handler.

alvaro is right about the performance... BUT..
if you do static handling per filetype, you will not be able to
serve that filetype dynamically generated by your cms/framework

Cherokee Reverse Proxy and Gzip

We are new to Cherokee.

Looking to use the reverse proxy features of Cherokee (under Ubuntu)
to protect and improve the performance of our application servers
(Windows based (IIS and ColdFusion)).

Currently, we have simple DNS load balancing going to between two
application servers that split load on our busy website.

We want to use the reverse proxy feature of Cherokee for load
balancing but also to shield our two older Windows/IIS machines from
direct access.

First question is - is this a typical and reasonable job for Cherokee?

Second question is - will Cherokee handle Gzip compression of the
outgoing data to viewers or should that be done on our app servers?

Sure it is.

Cherokee can work in both ways; it's up to you where you prefer the  
content to be gzip'ed.

Cherokee can handle compressed replies from your back-end servers, but  
it can also compress the outgoing responses if you prefer your  
application server to reply raw content.

But requires valid content types ;)
