Edward,
What do your Solaris systems look like? There are a number of things that can be done to get Sun systems, and especially their NICs, to coexist with Filers. I'm currently having a lot of fun getting some temperamental SBUS Gigabit NICs to perform up to spec (same problem - writes take FOREVER)

Hi all,
I hope that someone has gone through this as I have been trying to figure this out and its making me go nuts. On our solaris(2.8, 2.6) we usually do small file writes, our users do cvs checkouts to thier home directories and compile software that they are working on in that directory also. The problems is not the reads but the writes, I have changed the client machines to nfs3/tcp with rsize and wsize or 32k. The avg time todo a cvs checkout has been about 24 seconds, if this is done to local disk we are seeing the avg. of 4 seconds. The size of the module they are checking out is 4mb, this is what I have been doing tests with, but other cvs modules are also slow while being written to the nfs mount home directory. The filers also have the nfs.tcp.xfersize of 32k. Here are the configs of the filer:

We currently only use e6.

I hope you all can help.
