Results with graphs are in the attached PDF file.
Some rapid conclusions:
- Scientific Linux smokes all other operating systems
- DragonFly and FreeBSD performance is mostly the same, FreeBSD
degrades
faster under high loads
- NetBSD has trouble handling high numbers of database clients but
still
manages to scale when numbers are low
- Keeping processes on the same location they last ran on increases
performance by a few percents
Would you be able to try using local UNIX socket? NetBSD should have
nearly linear scalability, unless there is some regression. Going
through
127.0.0.1 is what kills us, I believe.
Thanks.
IIRC domain sockets are serialized...??
