I'm experiencing terrible NFSv3 read performance between Solaris 8
clients and a FreeBSD 4.6-STABLE server, which ran CVSup/make world
a day ago and thus includes the 'em' driver update (though that made
no difference).
Other FreeBSD clients and Mac G3 boxes running MacOS X 10.1.x can do
reads at fairly respectable rate - several MB/s over 100 Mbps ethernet.
The hardware:
Client: Sun E250, 2 x 300 MHz UltraSPARC II, 1 GB RAM, light load.
(Other Suns exhibit the same behaviour, though - this is an example.)
Server: Dell PowerEdge 1650, 2 x 1300 MHz PIII, 1 GB RAM, no load.
Network: all ports and cards at full-duplex, the Sun at 100 Mbps and the
FreeBSD box at 1 Gbps, switched through a ridiculously underutilised
cisco 6509.
The numbers:
NFSv3/TCP/32KB reads are going no higher than 0.5 MB/s.
NFSv3/TCP/32KB writes are nearly getting the full 100 Mbps.
To clear the network of blame, I've verified that ttcp can readily
transfer nearly 100 Mbps in both directions between these machines.
I've also used ttcp to blast several 100 Mbps streams in both
directions (ie. one2many and many2one) between the FreeBSD box and
several other 100Mbps Suns and everything scales just fine.
The Solaris client can read from other vendors' NFS servers at several
MB/s. Note that we're not using any jumbo frames, port channeling,
firewalling, etc. I'm using the default make.conf for the FreeBSD build.
Whilst performing "dd if=foo of=/dev/null bs=64k" on the client to
read a several MB file, the following is seen on the server:
freebsd# netstat -I em0 1
input (em0) output
packets errs bytes packets errs bytes colls
0 0 22140 0 0 478660 0
369 0 22422 637 0 449416 0
0 0 20693 0 0 444298 0
386 0 24301 635 0 482818 0
0 0 20346 0 0 410936 0
...and so on. (No, I don't know why the packet counts alternate between
zero and non-zero.)
Looking through the archives I see there have been some issues and/or
concerns with the effects of delayed ACKs, New Reno, etc. Trying the
various combinations of net.inet.tcp.{delayed_ack,newreno} has not
helped. Varying net.inet.tcp.{send,recv}space also does little, though
for the numbers in this post they're both at 64 KB.
I'm not savvy enough with TCP's intricacies or the code to dig deeper
at this point so I thought I'd see if those who do know more have ideas.
For your information, the dmesg output follows.
