Re: [Openstack] [Swift] Cache pressure tuning

2013-06-17 Thread Huang Zhiteng
d in the mean time drop VFS cache every once in a while (say every 60s). That's roughly the performance you can get when your storage system gets into a 'steady' state (i.e. objects # has out grown memory size). This will give you idea of pretty much the worst case. > Jonathan
