is there a way to determine how best to determine the number of mongrel processes to start? Right now i am running 2 in production but I see some people run about 8 or so. What is the cutoff and determening factor for this ? thanks adam -------------- next part -------------- An HTML attachment was scrubbed... URL:

Hello all, I''m attempting to test/tune a mongrel cluster according to the tuning instructions on the mongrel site (using httperf). Anecdotally, the site itself ''feels'' snappy, but testing it with httperf reveals what appears to be terrible throughput. I''m kind of at a loss to describe the results, and was hoping someone could verify that I''m testing incorrectly (enormously likely), or trul...

Hey Everyone, Topfunky (Geoffry) has created a great PeepCode screencast on using httperf to performance measure your web applications: http://nubyonrails.topfunky.com/articles/2007/03/05/peepcode-page-caching-and-httperf http://peepcode.com/products/benchmarking-with-httperf Topfunky put a ton of work into this and really got it right. The attention to detail is very good and he re...

hello there, ive downloaded and watched the peepcode screencast on httperf. i am now trying to see how much load my site can handle. quick question, while i run 1000 connections, while this test is running, and i go surf my site, is the site response times similar to as if my site is actually having 1000 connections? also, what does --rate do? does that say for each con...

Hi all Is there any way to limit the network i/o capacity of virtual machine somehow? Say, I want a domU with id 1 to consume at much 0.5 MB/s of host''s bandwidth. Is it possible?

I''m running on a brand new MacBook Pro with a relatively clean working set. using Mongrel in production mode on port 3000.

Hello Folks, This is the big release of Mongrel that''s been in the works for a while now (well, like a week). It is chock full of changes and features, but mostly it syncs up the Win32 side of things, and validates that Edge Rails works without problems. It also features a more extensive and useful example of the GemPlugins called mongrel_config. First the usual stuff for people

I tried benchmarking the same site behind an NGINX proxy with both fastcgi and mongrel, and for some reason mongrel is performing pretty poorly in comparison. Any idea what I might be doing wrong?

Hello Zed ! I''ve experimented a simple but limited performance tweak in the mongrel rails loader. With the following apache 2.2 mod proxy loadbalancer setup : # Redirect all non-static requests to cluster RewriteCond %{DOCUMENT_ROOT}/%{REQUEST_FILENAME} !-f RewriteRule ^/(.*)$ balancer://mongrel_cluster%{REQUEST_URI} [P,QSA,L] We can assume that mongrel is called only when the

Hi all, My environment is ruby-1.8.4, rails 1.2.2, mongrel 1.0.1, linux 2.6. Now, i have a problem on memory leaks with mongrel. My site is running 5 mongrel processes on a 2G RAM machine, the memory of each process grows from about 20M to about 250M, but it never recover to the initial 20M, so i had to restart the mongrel processes once per day. The load is about 1M hits per day. Waiting for

...an hypervisor related problem or a libvirt one. I did this experiment: on VM I started watching a video on youtube. While video was in progress I started migration. Migration did not complete until video was not finished. I did another experiment: I installed a web server on VM. I then started an httperf stress test. As before migration did not complete until the stress test was closed. Is this normal?

...ers (not just mongrel) under red hat enterprise linux ES release 4 (Nahant Update 5). Maybe this is helpful or somebody with deeper networking expertise can comment on this. Once client said that 1-2% of the response of our server were unacceptably slow (really huge 3s-21s). So I did more ab and httperf tests and notice that very few requests do take a very long time. Being clueless I first thought that the ruby garbage collector or mongrel is causing the effect, so after looking at a similar setup using erlang''s yaws or nginx alone, I noticed that sometimes this can happen, especially wh...

The bug only manifests itself when threads pile up behind the guard around Rails dispatching. T...

Hi list, I''m seeing a couple of issues with Mongrel. I''m running FreeBSD 6.1 and have previously been told that there are known conflicts between this and Mongrel, yet I hope these issues will be resolved with time. I''m overloading Mongrel with httperf on my local workstation. Mongrel is started directly with the mongrel_rails command and there is only one mongrel running. Soon I will start seeing: Server overloaded with N processors (M max). Dropping connection. Wed Sep 13 00:03:05 CEST 2006: Reaping N threads for slow workers because of '&...
