Your CGI is looking up something in a database, and the lookup itself is slow.

A cache engine takes a long time delivering an image.

A script is in a slow loop that blocks for a while.

The page is waiting for a resource that simply doesn't exist and times-out while waiting.

Suppose the HTML for that page was written poorly and it loads required scripts in the wrong order so the whole page renders slowly, even though almost all resources were in-place.

However, people often blame the network, when in-fact the speed issues are well-within their own control. Sadly, I can't list all possible network culprits here. Other sources could be a misconfigured proxy or cache engine. Packet drops are not the only reason for a slow network, but it's the most common source in my experience. even if it is just a link that's overloaded. If you find consistent packet drops, then you know for sure there is something in the network that needs to be fixed.

It starts with looking for packet drops between your client's browser and all the sources of images / scripts / html for the aforementioned web page. I suspect that it's due to a slow network connection. I can see this in the IIS logs as well, but the server's ASP.NET module logged it as taking 100ms, and CPU and Disk counters were low. I have a situation where a client will say, 'I sent a request to your web server at 10:03:24 and it took 20 seconds, why?'. Try to measure packet loss,round trip time and jitter (how many packets arrive out of sequence) to have some idea if network is not at fault. Try to tail webserver logs as you click around the redmine web interface to have some idea what is taking the most ammount of time to render.Īlso try to test your network connection to the redmine instance (not only with ping/ICMP) but also try loading some static content (download) or pushing some files (upload) over port 80 or 443. If you restart all the services that serve the redmine instance - is it running fast at the beginning and slows down after a while or it's slow from the begining ?Īs mentioned in the comments section - Disk IOs can be also at fault. MySQL may be running a long running query and so on. Try to re-check the redmine logs if there's any issue related to the processing of the pages or user logins if you're considering LDAP AD login to be at fault.Īlso please check the apache and mySQL logs - webserver may be busy with something else or ruby may be stuck on rendering an unsupported plugin for example. Very strange … but as I mentioned above, I have to re-check this one. It seemed like only Redmine-side calculated pages are slowly sent by the application server while Apache's still fast – but only when the request is a remote LAN request. Usually, I would think of a network problem, but the strange thing is: When actually measuring connect times, the network is fast as hell. It seemed like requests on localhost (Browser directly on the OpenSUSE VM) were fast, but requests over the network weren't. I tried to check if it's a network problem (network reacting slow, maybe DNS or something server is in the local network). One more thing that seems very odd to me, but maybe a false measurement result (need to re-check this tomorrow when I see the machine): MySQL indexes wouldn't be a problem given the fact that MySQL is very calm on the CPU, would it?.Is Bitnami's Apache2+Passenger config faulty?.Is Redmine 2.x maybe so much slower than 1.4.x that it's just plain normal?.But when not creating the user on the fly, does it keep a session only or does it re-authenticate on each request, so that could be the problem? But could the lack of a check here be a problem? Authentication takes a moment when logging in that's normal and acknowledged. I don't know if 'On-the-fly user creation' is checked in Redmine's LDAP settings, I can only check this one later today.Sometimes it takes 3 seconds, sometimes even up to 10 seconds to deliver the page. On each request, Redmine reacts unusually slow. What may be totally important: User login is handled via LDAP (ActiveDirectory). Also, there are only a few users accessing it.

The resources shouldn't be a problem, as there are always multiple gigabytes of free RAM and CPU spikes on Redmine requests go only up to 50% of 2 CPU cores. The stack is running on a Virtual Machine with OpenSUSE 12.1. imported the dump cleanly with recreating all tables.installed new Bitnami Stack with Redmine 2.1.0.So, if anybody has any ideas about this, please feel free to help 🙂īitnami Stack with Redmine 1.4.x upgraded to Bitnami Stack with Redmine 2.1.0 like this: Because I'm just trying to get to the bottom of this, I have some theories which I'd like to discuss here. I've got a Redmine instance (Bitnami Stack) that's unusually slow.
