Re: FreeBSD 7, DragonFly's status

As with the dragonfly 1.8 kernel, the dragonfly 1.12 kernel does not
scale to a second CPU on the benchmarks performed, and the limited SMP
implementation can cause a large performance loss at higher loads.
There is sometimes a large performance overhead from enabling SMP
compared to UP, and performance was sometimes worse than that of 4.11.
In all cases measured, FreeBSD 7.0 performs significantly better than
both FreeBSD 4.11 and dragonfly 1.12 in both SMP and UP configurations.
I've been running a FBSD home firewall since before DragonFly was born,
and I've never changed because it does what I need. Therefore I can
hardly be called anti-FBSD.
I think you will concede that FBSD started down a very bumpy road with
FBSD 5, but the subsequent improvement has been impressive, yes? I give
all the FBSD devs great credit for that.
Matt forked from FBSD because he had a different road in mind -- a road
that is just as long as FBSD's, but with a tiny fraction of the manpower
that FBSD has enjoyed in the meantime. If any DF evangelists have been
goading or taunting the FBSD people with claims of 'victory' I would hope
that the more mature audience would just let them pass as testosterone-
This project continues to rely on improvements imported from FBSD. I
hope that FBSD will likewise benefit from DragonFly. That's what the
opensource world is all about (but I'm preaching to the choir).
I will continue to follow both projects (and others) with great interest.
