swift currency calc

This page has description of the "concurrency" options in the configs:

http://docs.openstack.org/developer/swift/deployment_guide.html

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.
