We're doing some mysql benchmarking. For some reason it seems that ide
drives are currently beating a scsi raid array and it seems to be related
to fsync's. Bonnie stats show the scsi array to blow away ide as
expected, but mysql tests still have the idea beating on plain insert
speeds. Can an

Ahh, now we're getting somewhere.
IDE:
jeremy:~# time ./xlog file.out fsync
real0m33.739s
user0m0.010s
sys 0m0.120s
so now this corresponds to the performance we're seeing on SCSI.
So I guess what I'm wondering now is can or should anything be done about
this on the SCSI side?
I'm looking for anyone that has merged the international crypto patches
with Red Hat kernel rpm's.
I've basically gotten the patch to apply cleanly, but then the build
completely fails during module building. I don't have the know how to fix
things.
Thanks for any information.
I'm currently
So in the meantime as this gets worked out on a lower level, we've decided
to take the fsync() out of berkeley db for mysql transaction logs and
mount the filesystem -o sync.
Can anyone perhaps tell me why this may be a bad idea?
Thanks

Just curious if others have noticed that hotmail is unable to deal with
ECN and wondering if this is a standard that should be encouraged, as in
should I tell hotmail that perhaps they should look into supporting it, or
should I not waste my breath and echo 0 > /proc/sys/net/ipv4/tcp_ecn?
thanks
After mentioning ECN, this is the response I received from hotmail.
