Hi, all,
<br>
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.
<br>
<br>
Can anyone explain to me whether and why it is useful? I have
scanned the <a
href="http://docs.openstack.org/developer/swift/deployment_guide.html#general-server-configuration">Deployment
Guide of OpenStack Swift</a> but cannot find anything about such
tuning.
<br>
<br>
Thanks,
<br>
Jonathan Lu
