The main reason of poor network throughput because when you open a file, is not a simple open, read, and close. It sends lots of TRANS2 packets and the same file open and close several times before reading the whole files, lot of other weird network operations such as NTFS data stream checks. For small files, you probably see 3-10 times more packets transferred across the wire than the NFS. I think the performance difference may also depending on what type of file you are trying to open. For big files, (my very wild guess) you may see the performance difference converging to certain factor which is still more than NFS. The difference is even more when you open a network directory. I am in the middle of the process documenting on this issue. Will let you know more details in near future (if you are interested). ********************************************************************** This email and any files transmitted with it are confidential and intended solely for the use of the individual or entity to whom they are addressed.
