Problem: When connecting to work over VPN, SMB performance leaves a lot to be desired. Where a 200k file in the office loads in 5-9 seconds, over VPN it takes 50-60 seconds. It does not appear to be a server problem or a bandwidth problem. I tried the same file directly pulling it from an HFS and I got it loaded in 6 seconds from home. I then setup a file server on a z/OS box to see if it would perform better. It did not. Talking to local VPN expert, he basically said that SMB is "chatty" and that we will see some improvement with Windows Vista.
Reading the DFS manual for SMB, there are several notes about performance one of which states that HEAPPOOLS(ON) provides a significant improvement. What they don't say is what the heap pool sizes and percentages should be for SMB. I am overriding the HEAPPOOLS in the JCL so these will not be system wide. I tried HEAPPOOLS(ON) and did see a good improvement. Any help would be appreciated.
