...till way off the pace. There are similar patches for ssh at http://www.psc.edu/networking/projects/hpn-ssh/ which work wonders (up to 25M/s where previously we were at 700k/s). I would love to see similar performance gains from rsync as I've see from the tuned ssh...

I tried a bunch of tools and ended up using Jakarta J-Meter b/c it works cross-platform (Unix/Windows in my situation) and has a gui which shallows the learning curve. I''ve been quite satisfied with it.. Search the archives on this list and you should be able to find some great info Zed and others wrote a while back on How to Load Test Correctly. I found that series of posts to be

I am trying to create a proxy which I can route my browser requests through in order to gather information on the web page loading. At this time I am particularly interested in the many GET requests associated with loading a single web page. Note: This does not have anything to do with rails, my goal is to run a ruby app in the background, set firefox to proxy all requests through it, log those

Hi all, I''m messing around with has_many, and has_many :through (on edge rails), using a join model. Branches and Projects join through ProjectsAtBranches. If I do @branch.projects, I can see the associated projects, and visa-versa, if I manually put them in the join table. But I cannot do @branch.projects << Branch.find(blah), or @branch.projects.clear, and then save the

Hi, Thanks Zed - this is very interesting. One item in particular caught my eye: Does anyone on this list have any comments or validation that Rails 1.2.1 is 2-4 times as slow as Rails 1.1.6? Topfunky provided a link that purports what looks like really horrible performance and memory characteristics for Rails 1.2.1, even v. 1.1.6:

I thought all you mongrelians might appreciate this: http://xkcd.com/327/ I haven''t laughed out loud at a comic in a while. I realize it''s a working group but I figure many here might get a laugh today out of this one. Steve

Hi All, I am new to the mongrel mailing list and I have a question (and I didn''t find any answer in the archives). I have successfully installed the apache2.2 proxy balancer with mongrel cluster and that works just fine. For a single rails app I have started 2 mongrels which consume about 100M (ps says 5.0% for each and I have 1G RAM). It seems a bit much but OK. However that would

Hi, I have a database table and associated ActiveRecord model. I was trying to store (temporarily) an array in one of the attribute elements - not to save it, but just so that I can keep some form data in a sensible place. A stripped down version of the problem I''m having is: p = Property.new(:bedroom_count => ["2","3"]) puts p.inspect # ==> will correctly show

Hi all, We use mongrel behind apache (using mod_proxy_balancer) to run an internal app for our business. Lately we''ve been seeing frequent errors from some of our mongrel processes. [Sun Dec 16 08:48:47 2007] [error] [client <CLIENT1>] (70007)The timeout specified has expired: proxy: error reading status line from remote server 127.0.0.1, referer:

Hello, I''m running a Rails application which must sort and manipulate a lot of data which are loaded in memory. The Rails app runs on 2 mongrel processes. When I first load the app, both are 32Mb in memory. After some days, both are between 200Mb and 300Mb. My question is : is there some kind of garbage collector in Mongrel? I never see the two Mongrel processes memory footprint

Hello Everyone, I''d like to just officially announce that the new volunteers are in charge and given control of the project. I won''t be doing anything more than helping them get ramped up, but they''ll be in charge of doing all the stuff you folks want and are basically the owners from now on. Everyone in the new volunteer list will probably do a little announce, but

Hi, I''m wondering if it''s easy to add timestamps to the mongrel log? I am having a problem where an externally spawned application by Rails is failing. Mongrel kindly logs the error message returned by this application when it fails. But it doesn''t record a timestamp as to when the error occurs, which makes it a little tricky to sync this up to my webserver logs to

All, I am working on a multiple-regression meta-analysis and have too many alternative models to fit by hand. I am using the "metafor" package in R, which generates AIC scores among other metrics. I'm using a simple formula to define these models. For example, rma(Effect_size,variance, mods=~Myco_type + N.type +total, method="ML")->mod where Effect_size is the

Hi, I''m using RedCloth right now for some simple markup in a Rails project. It''s simple and easy - thanks for a great tool! I have a question about an apparent discrepancy between RedCloth and Textile, relating to newline characters. I''ve played with the "hard_breaks" feature and that seems to generate it''s own problems.. If I go onto the Textile

Hi mongrelians, I found myself with an unloaded full production server recently which presented an opportunity to run some performance tests against Mongrel and nginx. I thought this list might have some interest in the results of my tinkering! I actually ran two sets of studies, and Wayne Seguin kindly provided a lot of guidance and support in getting them running. Thanks Wayne! Also,
