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 ?

2352000 1329606  56%    0.06K  36750       64    147000K kmalloc-64
1566617 1257226  80%    0.21K  42341       37    338728K xfs_ili
1539808 1257748  81%    1.00K  48119       32   1539808K xfs_inode
538432 470882  87%    0.50K  16826       32    269216K kmalloc-512
403116 403004  99%    0.19K   9598       42     76784K dentry
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)?
