Well, have you seen my simple performance benchmarking RELENG_4 vs 6?
IMHO it mimics quote common usage pattern: it just downloads a large file
with 10Mbps rate and stores it on UFS filesystem. On the same hardware
(i386 uniprocessor Celeron-333 system with 128Mb RAM and fast SAMSUNG SP0802N
HDD using UDMA33) under the same conditions, using more optimal config
(INVARIANTS removed) RELENG_6 (and 5) _still_ uses >= 50% of CPU time
for (Intr+Sys), while RELENG_4 doesn't use more than 28% for them. So
(unless this performance difference will be minimized) I predict _a lot_
of requests to extend RELENG_4 support further, because people just couldn't
afford 4->6 upgrade due to a loss of performance.
