Hi . Someone know, how can i calculate concurrency for each swift's server ?
in my case i have 2 quad CPU with HT, 16 cpu's core after all.
I just set. object-server workers = 8 container-server/accont-server worker = 4
But, i have currency's options too. how can i calculate currency for servers?
Thanks
Jose Augusto
This page has description of the "concurrency" options in the configs:
http://docs.openstack.org/developer/swift/deployment_guide.html (http://docs.openstack.org/developer/s...)
Defaults are normally fine.
Thanks Clayg.
There's interesting things there. One in specific, there are some places with this comment "Should be tuned according to individual system specs".
I will change somethings for test, in relation cpu x workers, in my case i'll have small quantity container changes and heavy use to write objects in server.
Now with the same server i got 50 request more of the first configuration, after improve the workers and change some options concurrency.
Do you know where can i find some example to "individual system specs"? for small objects, 20k ~ 40k.

The -auditor options have mostly to do with disk speed. I'm not sure enough folks are tweaking those values to really justify those comments.
Changing them will effect I/O on the nodes. You'll first have to start monitoring -auditor cycle time to get a feel for how tuning them down (to decrease the ambient I/O) will effect the auditor cycle time. If you've sufficiently scaled with a good balance of hot and cold objects, and enough i/o headroom you might turning them up to get faster bit rot detection.
