Hi Jose ! Thanks for answering !
Your explanations are very appropriate and I couldn't agree more !
In fact, I'm just concerned if squatter causing a high load on a core even when running with nice 19 is the normal behavior, but I realize that it is more a question about Linux than Cyrus.

I think that it is more appropriate measure the total usage of cpu of the server.I think that monitor for detect a high load in a core isn't appropriate measure of performance. It can be useful for detected a hanged process that takes all your cpu, or historical usages of the cores, but not for other purposes.I am not a cyrux expert, but why are you worried that a core is loaded?It means that the core is working on the task. Does the performance of the server suffer because of this (response time to users, etc)?

Thank you Bron ! Once I unfortunately do not have the knowledgement necessary to create this patch, I will adjust my configurations to run squatter at specific times and disable the CPU consumption trigger on my monitoring solution.Even if when running with nice 19 my squatter process causes a high load on the core which it's running, it this behavior normal?Thanks everyone for answering this thread, I know that my english is not so good but I'm trying to improve it !--My best regards, Fabio Soares SchmidtOn 15 July 2014 03:03, Bron Gondwana <brong@xxxxxxxxxxx> wrote:
Yes, all Cyrus processes are single threaded except mupdate. I don't think that running squatter on multiple cores would necessarily be an improvement - and regardless, it's not a priority for me to implement. We'd accept a patch if someone did it and it integrated with the other stuff that's floating around on the fastmail branch.

Has this behavior been improved on newer versions?Here is my entry:squatter_1 cmd="/usr/bin/nice +n 19 /usr/lib/cyrus/bin/squatter -s -i -r user" period=180
I do run it with "nice +19" but It causes a high load on the core it's running and triggers an alert on my monitoring solution. I know that this alert could be deactivated, but maybe I'm doing something wrong with squatter.
