We have recently switched MediaWiki from PHP 5.3 to PHP 5.5. As such the workload as been shifted from Precise instances to Trusty instances.
To accommodate for the new workload, we have added six labs instances ci.medium (2 CPU, 2GB RAM). Turns out there is not enough memory to run two jobs in parallel (we had a bunch of oom errors). Thus we changed the Jenkins slaves to only run one job.
To get more jobs run in parallel, we would need to add 8 more c1.medium slaves instances to the integration project. We have reached the quota, and this task is about raising it.
For 8 more executor slots we would need 8 ci.medium or:
|Quota||ci.medium||8 of them|
We would need:
- CPU quota raised to 97 (85 + 12)
- instance quota raised to 37 (29 + 8)
The quota summary is:
|RAM||151552/204800||~ 167||+ 16 GB|
Not sure whether labs infra can handle it. If you get enough resources, maybe 100 CPU and 40 instances quota?
