Interesting...I followed the job and got a big increase in writing the
tape using "Spool Attributes = yes", went from 2.66GB/minute toe
3.8GB/minute, but but the job took longer to finish, close to 50
minutes writing out attribute data to mysql. Looks like putting the
sql on a ssd would help. Nice option for testing, thanks....

2:04 with Spool Attributes=yes  3.8 GB/minute, with system busy
1:37 w/o  Spool Attributes=no   2.66 GB/minute
