Re: [PATCHES] Bitmapscan changes

This is on dual ultra 2 sparc. with ultrawide 320 scsi drives. 512MB
ram.
I had to drop size of DB, because the DB drive is 4GB (I do welecome
bigger drives as donation, if someone asks - UWscsi 320).

here are my results. With only 4.2 patch (no maintain cluster order
v5 patch). If the v5 patch was needed, please tell me - I am going
rerun it with.

hope it is usefull.
