Slow initial startup on Django project
Hey everyone, I'm not considering this a "problem" so much as it's annoying. I moved a project I'd been running locally under mod_python to a shared server (on Dreamhost) using fcgi. I've noticed that when I first visit the site, it takes somewhere between 1-10 seconds to actually load the index of my app. I know the HTTP server is responding quickly because, well, I have it htaccess password protected and that pops up immediately, and I have a ton of other sites on this same server with no slow startup issues. Any ideas about what causes this "slow startup" phenomena? Is it just inherent to fcgi or is there something wrong with how I'm doing business.

If so, it's most likely just the startup costs of the Python interpreter, Django, the database connection, and the operating system loading everything into caches. That is, normal. (I also wouldn't expect to get great performance out of Dreamhost; I've had no end of headaches diagnosing performance issues there.)

Re: Slow initial startup on Django project
Clint, I believe this is a fcgi thing. Dreamhost kills it after a perdiod of inactivity, which means that the first request after a few minutes of stillness has to load django & everything else. Later request should respond better. There are mixed reviews on dreamhost and django on this list, quite a few topics bring this up. It seems to depend a little in which server you are (I am on pound, and haven't had any issues). But at any rate you are not going to achieve *great* performance on django. hope that helps, arthur --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

I've had fantastic performance on Django on several servers (both Linux and Solaris). Frankly, it knocks the crap out of any other dynamic-language framework I'm aware of, performance-wise.

Re: Slow initial startup on Django project
Oh My! my bad. yes that should read.. " are not going to achieve *great* performance on DREAMHOST." I just meant to say that dreamhost has nice price / feature ration but it's just a little unreliable to host a *critical* site on it. Isn't it great that you could just read through my mistake (and have no doubs that I was talink about dreamhost...)? cheers --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

That keeps it alive pretty much, so the only time I get the dreaded 1-10 second startup penalty is when I kill everything and start it up from scratch. Once you figure out the ins and outs of FastCGI on Dreamhost, it's really not so bad. - jmj --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Slow initial startup on Django project
I had *many* problems with Django on Dreamhost the first two weeks that my systems ran there. Suddenly there are no more... I don't know what they did, what I did, or anything else. There's a page on the Dreamhost panel for you to vote on new features that they should add. Maybe +1 on an "official" Django support (like they have for RoR) would help.
