-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 hi,
i have two systems, A (Solaris 10 update 5) and B (Solaris 10 update 6). i'm using 'zfs send -i' to replicate changes on A to B. however, the 'zfs recv' on B is running extremely slowly. if i run the zfs send on A and redirect output to a file, it sends at 2MB/sec. but when i use 'zfs send ... | ssh B zfs recv', the speed drops to 200KB/sec. according to iostat, B (which is otherwise idle) is doing ~20MB/sec of disk reads, and very little writing. i don't believe the problem is ssh, as the systems are on the same LAN, and running 'tar' over ssh runs much faster (20MB/sec or more). is this slowness normal? is there any way to improve it? (the idea here is to use B as a backup of A, but if i can only replicate at 200KB/s, it's not going to be able to keep up with the load...) both systems are X4500s with 16GB ram, 48 SATA disks and 4 2.8GHz cores. thanks, river. -----BEGIN PGP SIGNATURE----- iD8DBQFJE3k5IXd7fCuc5vIRAs2JAJ0W0dYVgfyNUXGWHbg59D5mQgq9jQCfWUsm 5/c8g4JMmtIj59mZ5ghkdIY= =QNG3 -----END PGP SIGNATURE----- _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
