I've to do some benchmark test on my 2 sites Moodle: one is working on mysql and the other on postgresql! I'use Linux, Debian distribution!
I've to complete my databases, I've to try simulate a university. But, I'don't know how to do this in a few time. I've tried with ab (apache benchmark) and httperf, but those tools support only a cookie per request, while Moodle use 4 cookie in a http post!
There's someone than could help me?
What to you thin about connect every body to my site so I can do my test :P ... I' will be more easy...
I find the cookie, but when I do my http post request moodle return an error page.
I use etherreal to sniff the cookie from a request build by moodle, then I use ab in this way:
ab2 -p assignmentpost -H 'Host:moexsi.dyndns.org' -H 'Referer:http://moexsi.dyndns.org/~sue/moodle-postgres/course/mod.php?id=4§ion=0&add=assignment' -H 'Accept: text/*' -C 'MoodleSession=31bf95828e65a2ecfbe3258c8bec0a0a' http://moexsi.dyndns.org/~sue/moodle-postgres/course/mod.php
The reply is HTTP 200, ok, but, in the packet of the reply there is the html error page, and I don't write anything on my db.
Thank'a lot Matin
did you get any further with your benchmark test to simulate moodle in a university environment? Your results and experiences will be extremely valuable to other universities who are considering whether to adopt Moodle for their institutional VLE.
I think that the test you are doing is the interest for all universities. I would appreciate if you could send me the test when you will finish it. Tyhnaking you in advance,
-C attribute Add cookie, eg. 'Apache=1234. (repeatable)note 'repeatable'. Have you tried passing all the 4 cookies? I am trying to benchmark as well and am having the same problem trying to benchmark resource intensive pages and activities. I think there needs to be some more reliable information about Moodle scalability. Even though it'd be hard to be exact, some sort of guidelines would be useful during evaluation.
redirects, and have many pages with different relative loads, I use
JMeter. It is a Java toy, you set it up as a proxy, and use mozilla to do one or more "normal user sessions" through that proxy. The proxy records everything, and you can ask it to replay it against the server, times 1000 (or whatever).
Some things are well known to be performance hogs:
- using 'groups' within courses
- displaying the calendar when there are many courses, and for users enrolled/teaching in many courses
- courselisting and moving courses around (up/down)
A lot of performance work is going into 1.4.3 and 1.5. Get good numbers from 1.4.2 so we can compare and brag ;)
I can't login to Moodle using httperf --wsesslog option.
my urifile has:
/moodle/login/index.php method=POST contents='username=user&password=123'
command I issued
#httperf --hog --server localhost --port 80 --wsesslog 1,0,urifile --print-reply --num-conns 1 > outfile
output shows 'you are not logged in'
Any help is appreciated....
I am trying to load my Moodle using a set of URLs such that it mimics a real user working in a session. When I send just username and password as mentioned in my earlier post I get a page saying 'you are not logged in'
I am wondering what I should do about the MoodleSession cookie for getting a session maintained using httperf
Could anyone pls help?
The problem was that I did not specify the content type at the httperf command.
httperf --server localhost --port 80 --wsesslog 1,1,myfile --print-reply --add-header="content-type: application/x-www-form-urlencoded\n"
Earlier $_POST array did not get populated, for my own simple php script. But after I used the option bold faced above it got ok.
But still the problem is with Moodle login page ....
Ealier I was thrown back to logn/index.html. But now end up in location.replace (http://localhost/moodle)
