Is Hosed, on 2.1.0 NFS will write to a sun server at a whopping 100K/sec over
ethernet, but it goes along happily just slowly.
On 2.2-961006-SNAP we also write to NFS at a whopping 100K/sec, however in 8MB
increments we write out at 600K/sec (apparently into some memory buffer??) at
which point the buffer fills, all NFS operations are locked out on the system
until the buffer is drained. This takes an eternity. How do I undo this
buffering mechanism or make it a tunable?
Also an interesting note, a SGI to the SUN writes at 900K/sec via NFS with no
problems. The SGI is apparently doing:
NFS v3 Proc 6, Proc 7 (Data)
The FreeBSD box does:
NFS v2 Proc 8 (Data)
or
NFS v3 Proc 7 (Data)
Both are horrendously slow. Im going to attempt to figure out what the hell
Proc 6 is (everything I see says read, which doesnt make alot of sense). In
any case Im not much of a kernel hacker, so any assistance or someone with a
solution, please raise your hand! :)
