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)?
