Subject: readpages and network file systems

Hi
Am I right in saying that the kernel has a maximum of 128K readpages? I
saw some discussion in the archives relating to the efficiency of reads
that size in the context of block devices, and a lot of people were
saying that reads shouldn't be larger than that because of various
problems, but what about network file systems? I'm implementing read
ahead routines in cifs, and i think reads in the megabytes could greatly
increase bandwidth utilisation, as you can have up to 50 cifs requests
of 64K each on the wire at any one time. The larger the reads, the less
the round trip time has effect.
Please CC any responses to me as I am not on the mailing list.
James
