## SYMPTOMS

You cannot connect a sufficient number of users with Mac Services.

## CAUSE

Mac Services is resource intensive and its 1-MB available memory default setting is enough for only a few users.

## RESOLUTION

Raise the MSFM parameter to 4 MB and reduce the cache to 2 MB. You can vary these amounts (in the 6 MB range) by, for example, raising MSFM to 3 MB and using 3 MB for cache, but the 4-and-2 arrangement has worked better in tests.
You can also set the cache to 2 MB and delete the MSFM parameter. This allows the memory for services to use all available memory not assigned to the cache, and reducing the cache in many configurations does not degrade performance.
You should also add a line to the ATALK_XIF section in the PROTOCOL.INI file, raising selectors to 2(# of users) + 2. The theoretical maximum number of Mac users is 50, for which Selectors = 27.
