Re: Django Web Hosting Service
Although more expensive ($34/mo), I found highspeedrails.com to be excellent--you can also host multiple sites on one account. As my webfaction sites grew, they didn't hold up the way that highspeedrails.com did. I eventually moved things over there. --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Re: Django Web Hosting Service
I have had two small Django sites running on asmallorange shared hosting for more thane a year. It took quite some time to get working in the shared environment, but then worked ok. The server reposne to the first hit on the site is slow to respond, but then ok. I just recently moved to a VPS account on linode.com, and am very happy so far with performance and low cost for a VPS option ($20/month).

I'll admit I don't have first had experience with WebFaction, but given that they have a limit on the number of persistent processes you can have, this would be a severe restriction as it would limit the number of concurrent requests your overall application could handle quite drastically, as any spike in requests would require extra Apache child processes to be created. Thus, if you have a steady streams of requests, you would be stuck on your process limit quite quickly and so limit your throughput. I could understand them using prefork for the static file hosting, but for users own applications proxied behind their front end, using prefork doesn't make a great deal of sense to me as far as trying to use memory resources as efficiently as possible. Anyone else able to confirm how they setup the Apache instance which a users application runs in, not the main server used for static files? Irrespective of whether prefork is used instead of worker, in both cases there are a range of other issues that can also cause bloating in memory. With WSGI frameworks which use yield in some way, one such issue is where a user generator doesn't implement close() method for reclaiming resources immediately. As a consequence the reclaiming of resources can be deferred until the next GC cycle to try and break reference cycles between objects. Such reference count cycles can also occur in other situations as well, so not trying to clean up and aid garbage collection, by breaking cycles up front, can result in an accumulation of unreclaimed objects until the next time that GC runs. If other requests come in before GC kicks in, then total memory in use can end up growing more than one might expect.

They use the prefork version, so I'd suggest Kenneth look for other possible reasons for his memory spikes in his app. My 2c on the original topic of this thread... I've been hosting with webfaction for 2 years and frequently monitor the resource usage on the shared machines hosting my sites and those of my clients (also on webfaction). Not once have any of the machines I monitor been under even moderate load, let alone heavy load - which to me speaks to their commitment to never push any of their machines to the max with user applications. Uptime has been over 99.9% for me and their support has been prompt and without fault to date.

One should possibly heed my response to prior question about memory usage. http://groups.google.com.au/group/django-users/browse_frm/thread/7670886c04ac082d In short, if you are running Django in worker MPM for Apache, you can be subject to sudden memory increases when you get concurrent requests against resources which chew up a lot of transient memory. Receiving a lot of concurrent POST requests with large content data can be one trigger if the framework reads such POST content all into memory at the same time. The problem is that more often than not people don't understand the dynamics of how the underlying hosting system actually works and the implication of using multithreading. Thus, they tend to blame the hosting system, rather than taking preventative measures in their own application to avoid it. I believe that what is going to have to start happening is that the web frameworks themselves will have to start having protections built into them in some way to counter such problems. For example, the web framework could temporarily delay a POST request in a multithreaded server where there are already some specified number of requests already running, or the POST content size for existing requests has exceeded some set value. Similarly, where users know that specific URL handlers will consume a lot of transient memory, they need to be given a way of putting restrictions on the number of concurrent requests that might be allowed against that resource or such a group of resources at one time. As long as people want to run big Python web applications in memory constrained web hosting configurations, where Apache worker MPM with a small number of processes is the only viable solution for Apache, in contrast to prefork MPM which isn't, this is going to continue to be an issue. The only solutions are going to be to somehow have the web applications themselves throttle concurrent requests, or at least try and temper the issue with hosting solutions which allow more flexibility in defining how often web application processes should be recycled in order to reclaim memory, or which are able to themselves monitor memory usage and force process restarts when threshold values are exceeded.

Re: Django Web Hosting Service
Hello, > then why do you recommend that apache be restarted on 17,37 and 57 minutes? > In fact *you* yourself install that cronjob on all django sites.? The cron job you're referring to: 1) Exists because if you've a spike in CPU or memory usage that affects others on the same server your processes will be killed. If we kill your processes the cron job ensures that your website won't be down for too long. 2) Only restarts your instance of Apache if it's down. > debug is false everywhere, apache is tweaked as per your recommendations and > static media is served through the system wide apache.

A memory leak isn't the only reason that your instance of Apache could be using more than 40 MB of memory, off of the top of my head I can think of nearly half a dozen reasons and I'm just WebFaction's Django monkey. With that said the memory usage related Apache/Django tips that we've in our blog are by no means a one size fits all solution for decreasing Apache's memory usage. -David Sissitka --~--~-~--~~~---~--~~ You received this message because you are subscribed to the Google Groups "Django users" group.

Another +1 for webfaction. The cheapest plan supports Django, 7.50/mo for two years in advance, but you can get a refund for your remaining time if you're not satisfied. Pretty sweet deal.

Re: Django Web Hosting Service
I'm enrolled in the Media Temple Django Container Beta Testing programm, and so far, it's an absolute killer. They've been working close with the Django guys to make it somewhat the "official" django hoster. The django site itself is hosted on a media temple server. Though they're still in Beta, and not publicly available, you could try to ask them if you could get a container to try it. You'll need a grid server account, though.
