Hi,
I'm showing slow zfs send on pool v29. About 25MB/sec

pool: vdipool
state: ONLINE

The drives are in an external promise 12 drive jbod. The jbod is also
connected to another server that uses the other 6 SEAGATE ST31000640SS
drives.
This on Solaris 10 8/11 (Generic_147441-01). I'm using LSI 9200 for the
external promise jbod and an internal 9200 for the zli and l2arc which
also uses rpool.
FW versions on both cards are MPTFW-12.00.00.00-IT and MPT2BIOS-7.23.01.00.
I'm wondering why the zfs send could be so slow. Could the other server
be slowing down the sas bus?
