Synopsis: performance regression for sequential/random creation of files, as 
well as stat(2) (ffs fs)

State-Changed-From-To: closed->open
State-Changed-By: dholland%NetBSD.org@localhost
State-Changed-When: Tue, 03 Jan 2012 14:48:29 +0000
State-Changed-Why:
I don't agree - a 3x performance degradation from DIAGNOSTIC (even on a
naive benchmark) is not acceptable.

Are you in a position to check where it's coming from?
