I am a user of Chamilo 1.8 as my Website is : www.team**.in and i am having about 1300 users registered on that portal
but i always face big problem with chamilo 1.8 that when i take test of all users on same day then it stops working.
chamilo 1.8 is not able to handle online users more than 40, so i am facing big problem right now.
Sir, i want to ask u that should i upgrade or use chamilo 2.1 so that i can handle up to 2000 users online at same time for better output.
or please give me the solution for my problem .
Waiting for your response!
You can try Chamilo LCMS Connect 2.1 if you want, but:
– there is no working upgrade mechanism from Chamilo LMS (1.8, 1.9) to
Chamilo LCMS Connect (2.1, 3.1) at the moment
– Chamilo LCMS Connect 3.1 should be out in a few days now
– Chamilo LMS 1.8 is *much* lighter than Chamilo LCMS 2.1 as far as we
know, so upgrading would definitely not fix the weight problem.
Apart from that, you might be interested to know that:
– Chamilo LMS 1.9.2 will be released this week (but it is a bit heavier
than Chamilo 1.8)
– Chamilo LMS and Chamilo LCMS Connect have no real common point (apart
of the fact that they are managed by the same association and are LMS
– there is an optimization guide in the documentation/ folder of Chamilo LMS. Please
read it and make sure you apply a few hints from there to your portal.
You might get great improvements in speed if you know a little bit of
optimization principles (for example showing the number of connected
users adds a massive load time to each page if you do not use any shared
memory variable caching)
– 1300 registered users shouldn’t be a problem. However, the number of
*simultaneous* users is really where the stress might come from. The
hardware you use for this site will be the issue if you use a virtual
machine with low resources, for example. Do not think of an LMS as a
blog or website: in an LMS, all the content has to be personalized,
which is much more difficult to optimize than a website, where the
content is the same for all users.
I’ve had a look at the reports for the homepage (can’t go further
without login) of http://www.team***.in/elms/ and it seems
alright (C-Rank without optimizations is rather good).
Taking a test for 1300 users simultaneously will
*obviously* put a lot of load on the database. You could reduce the load
by trying different settings, like having all questions on one page
instead of one question per page (because people will finish the exam at
different times and will only send one big SQL request at the end of the
test, which will hopefully be treated faster than one request every time
one single person answers one single question), or adding in-cache
indexes to your MySQL database but, most of all, you will need to have
a solid database behind your site (having it on a separate server to split
the load between php and MySQL might be a good idea).
