[Swift][Object-server] Why that arp_cache consumes memory followed with uploading objects?

 

Hi all

I found that the arp_cache in slabinfo on objec-server is growing up
followed with uploaded object numbers.

Does any code using it ?

169250 145824  86%    0.31K   6770       25     54160K arp_cache


Does it may cause any performance concern ?

Btw , how could I flush the memory of arp_cache which using by XFS(SWIFT)?
