[Openstack] [Swift] Partition count

I have a Swift setup with 8 disks of 3TB each. I went by the suggested
config of having over 100 partitions per disk. However, with this I'm
see that performance to be really slow.

I reduced the number of partitions to about 8 per disk and the
performance has gone up by almost 5x.

I realize that lesser partitions would mean larger replication time
if/when it is needed. Are there any other side effects of reducing the
# of partitions?

Thanks in advance.
