Hi,
I use FC6 to master DVDs and have noticed if I add the -J option to
the mkisofs command the read performance on the final dvd is severely
degraded.
I tested four blades at work yesterday (all same vendor/model) and they
all drop to 30%, sometimes 20%, read performance with Joliet enabled.
Will start digging into the f/w updates for the blade mobos and dvd
readers tomorrow. It gets a little weird because we are testing a known
buggy 3rd party kernel driver and pci card in them.

Posting for completion. This was H/W related. Out of 12 servers tested,
3 had problems reading at their rated speed. Sometimes it depended on
the media.
One unit (the worst offender) started working properly after the drive
was removed and reinstalled (perhaps the cables needed re-seating?)
Anyway, no real problem here.
