Title: Slow and aborted loading of forum pages
Post by: Nexus on November 10, 2012, 10:10:09 am
Recently, the loading of SFML forum pages is often slow. With both IE 9 and Firefox 16, pages sometimes take 10 seconds or more to load. With IE, it happens often that an action (like post/edit) is not sent at all -- the loading aborts after some seconds.

I don't know why this happens, if it's just my configuration, but it only happens since a few weeks. Has anyone experienced similar issues?

No problem on my side, I'm using Chrome.

I can confirm this as well and I'm using Chrome too. (See my PM from last week.) :-\

I've been experiencing the same issue. Doesn't seem tied to a particular time of day but happened just now, loading this thread. Firefox 16.

Might it be related to the Tapatalk mod? The timing could be right, or have you recently changed other parts of the forum?

Had similar issue (slow, partial or aborted loading) for both forum and site at extremely rare occasions, before the tapatalk mod.

The same happens to me sometimes, I use firefox as well (can't remember which version I have though).
Sometimes it happens for an entire day while others I don't get the delay at all.

I'd say there were problems too before but I can't quite judge.
Also I'm not sure how the mod hooks itself into it, but I wouldn't see how this would cause the problem.

Chromium on Linux.  Same issue here.  Perhaps it's latency with where the server is located?

Same issue here. Seems like your hosting package is overloaded. ;-)

Yep had similar issues, usually its night time here (at GMT+10) when it seems to happen. Will hang when loading forum, posting a reply, etc. Also I got a 404 when visiting the front page last night which was weird.

@Laurent: Are you considering to move/upgrade, because those "(net::ERR_TIMED_OUT)" are really start to get annoying... :(
Or at least try to communicate with the hoster to figure out what is going on and if it's really the load or just the forum software or similar.

Yep, I'll try to find the time to do something (don't know what yet...).

Thought I'd add half loaded page screenshot.

Yeah I get that too from time to time.

I can confirm this as well. It was fine for a while (a few weeks ago the forum refused to load at all, for a few days straight) and then yesterday I got a few timeouts as well.

This looks to me like an overloaded backend service/daemon. I recently reconfigured one of my websites and tuned the PHP settings of my daemon to match the expected load of the website. If you tell the daemon to spawn too little PHP processes/threads eventually it will drop requests if too many come in at the same time, which is what leads to those pages without CSS. If it was a network traffic issue you would either just wait a long time until the TCP retransmits get through or the server would just reset the connection which would produce some error message in your browser after a short time.

I don't know whether you already have a reverse proxy/web accelerator set up yet, but that might help with this problem.

Well I've experienced both scenarios a few times. The first one a bit less than the second one, but it's obvious that the server are somewhere overloaded...

Forum just died for couple minutes for me, there was an erorr page saying server is busy.

Same here, I don't really know how much time though. I checked twice in three minutes and then half an hour later so I can't really say how much did it last.

Simple! If you're using pure webspace: upgrade or change the hoster. ;)
