Work very fine (I can't say I've long experience because the server is up
since just 4 months).
The ZFS is very good, easy to manage, very fast.
i dare not to agree about "very fast". very fast is relative term. how did
you configured your storage?
trivial test:
make 10 100GB files (so none fits in RAM) by
for x in 0 1 2 3 4 5 6 7 8 9;do ( dd if=/dev/zero of=testfile$x bs=1m
count=100k &) ;done
measure time needed for it to finish (all dd processes exist)
then install /usr/ports/benchmark/randomio and do some tests of random
reads on that files.
and final test - 10 randomio in parallel with 10 threads each, one per
every file.
then sum up results (IOPS) and divide by amount of disks you have.
then decide if is it fast or slow :)
They're two default IMHO :
Eat lot of Ram
can be controlled by settings in loader.conf.
