Hi Julien,
thx a lot for the real quick help.
Yes, only swift. These meters:
storage.objects
storage.objects.size
storage.objects.containers
storage.objects.incoming.bytes
storage.objects.outgoing.bytes
To be sure, the ceilometer-agent-central and ceilometer-collector do
go on the proxys.

No, they all can go to your dedicated host. Ceilometer agent central

Yes tempurl and and tempauth are tessted together, your pipeline looks good.
allow_overrides = false in the tempauth section could cause this, but
it's default is true.
Are you creating the tempurl's with bin/swift-temp-url ???

I'm facing the issue about the performance degradation, and once I glanced
that changing the value in /proc/sys
/vm/vfs_cache_pressure will do a favour.

Hi,
When this is set to a lower value the kernel will try to keep the inode/dentry

Hi Jonathan ,
How did you perform delete all the objects in the storage ? Those
deleted objects still consume inodes in tombstone status until the reclaim
time.
Would you mind to compare the result of $ sudo cat /proc/slabinfo | grep
xfs , before/after set the vfs_cache_pressure
Hi Hugo,
I know the tombstone mechanism. In my opinion after the reclaim
time, the object of xxx.tombstone will be deleted at all. Is that right?
Maybe I misunderstand the doc :( ...
We try to colddown the swift system ( just wait for the
reclaiming) and test, but the result is not
Hi Huang,
Storage nodes will run out of memory for caching inode eventually right?
Have you ever measure the upper limit of caching capability of your
storage nodes?
Hi Jonathan,
The default reclaiming time is 7 days. Did you wait for 7 days or just
change the setting to 1 min in conf file ?
Hi, Huang
Thanks for you explanation. Does it mean that the storage cluster
of specific processing ability will be slower and slower with more and
more objects? Is there any test about the rate of the decline or is
there any lower limit?
For example, my environment is:

Hi, Huang
Thanks a lot. I will try this test.
One more question:
In the 3 following situation, will the base line performance be
quite different?
1. only 1 sontaienr with 10m objects;
2. 100,000 objects per container at 100 containers
3. 1,000 objects per
The global clusters feature is Swift is very new and just now being finished
up. We are finishing up the last part of it and will have it completed in our
next release (tentatively scheduled for June 27). The last part is the affinity
write (ie don't write to a WAN region).
The regions concept
Thanks John for the quick response and update.
I followed the guide at
http://docs.openstack.org/grizzly/openstack-compute/install/apt/content/ch_installing-openstack-object-storage.html
and I am using Grizzly on Ubuntu 12.04LTS. Two replicas in A and one
replica in B is what I intended so looks

paying close attention to Swift's changelog:
https://github.com/openstack/swift/blob/master/CHANGELOG. There are several
things described in there that you should pay attention to (eg changing config
defaults and some format changes). Everything has an upgrade path, so, although
you may elect
