Hi, in any recent distribution that I tried, the default NFS wsize/rsize
was 1 MB.
On 10/100 Mbps networks, this causes severe lags, timeouts, and dmesg
fills with messages like:
> [ 316.404250] nfs: server 192.168.1.112 not responding, still trying
> [ 316.759512] nfs: server 192.168.1.112 OK
Forcing wsize/rsize to 32K makes all the problems disappear and NFS
access more snappy, without sacrificing any speed at least up to gigabit
networks that I tested with.
I would like to request that the defaults be changed to 32K.
But I didn't find out where these defaults come from, where to file the
issue and my test case / benchmarks to support it.
I've initially reported it at the klibc nfsmount program that I was
using, but this is just using the NFS defaults, which are the ones that
should be amended. So initial test case / benchmarks there:

Please Cc me as I'm not in the list.
Thank you,
