I found some old information on Middle Tier, but I couldn't find anything on the recommended number of connections for ZFD 7 sp1 (or no sp) on Windows 2003. I saw the cool solutions article, but it didn't say those numbers were recommended, max or just numbers.

yes zfd is old, but I am looking for an existing install and need to know if I need to add more middle tiers.

TCP registry settings have already been set. Wondering what errors would start to show if we needed to add another middle tier.

There is no file delivery through middle tier, it is all through SMB file shares. This is an all MS shop install.

Middle Tiers are fronted by a L4 switch.

Looking for Max # of concurrent connections recommendation.
