Hello Stefan,

I noticed that in 2.1.5R, /usr/src/sys/pci/ncr.c, there is a constant
limiting SCSI_NCR_MAX_TAGS to 4.

Assuming that I am using fairly modern drives (Seacrate ST31055N
"Ultra-SCSI" Hawk-2 1GB, Seacrate ST15150N Barra 4GB), is there a
problem with raising this constant?

What would a good number be?

Always looking for a performance tweak or two,

... JG
