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