Hi,

I am thinking of adding read-ahead to a 9p server.
Is this a sensible thing to do? Am I being foolish
and indulging in bloatware or is it a sensible
optimisation?

My server is my Netware client. Directory scans of big
directrories is slow as is copying files. Looking at
iostats it looks like read is at fault. Netware
allows me to read big chunks of files and to scan for
multiple directory entries, So this is fairly easy,

I was planning to add a timeout on the buffer of
a seccond or two, so I don't get stale info.

Anyone any strong views about this?
