Did you try remounting with rsize and wsize of 8192? I had this problem if my filer was running a gig-e card and my solaris clients were using 100mb cards. This may not be your case but it sounds similar to my performance problem.

Toasters,
I am having difficulty with large file writes to an f720 from any of my IBM hosts, if I start a large write with dd then try to do anything on the filer from that host it hangs until the write completes. From a different host access to the filer is near normal. I do not have this problem with linux boxes on the same network so it seems that the problem lies with AIX somehow. IBM has been sympathetic although not very helpful.
Any thoughts would be much appreciated.
