My original post claimed ~6 to ~2.5 due to softupdates. The ~6 was heavily disputed, though, and I had to concede that it may have been substantially less, like ~4. > What were the main tricks to speeding your system up? 1. I seperated /usr/src and /usr/obj onto two seperate physical disks. 2. I uncommented the "CFLAGS= -O -pipe" line in /etc/make.conf (which really ought to be the default). 3. I mounted both disks async (I thought some crashes/hangs I was having may have been related to softupdates). Since then, I have gone back to softupdates (since I traced the problem to something other than softupdates). In fact, I don't believe I've had a single softupdates related crash so far (* knock knock *). I haven't reran the worldstone test yet, though. I'm waiting for the recent rash of -current problems to settle a bit. > (I have been less impressed than I could have been using async,noatime.) For speeding up writes, there's nothing like softupdates (if you're brave, and the system is not for production use that is...). > Thanks! No problem.
