wcMail Speed

WcMAIL mail importing was originally designed to address UUCP/News Host Distribution systems, Uucp/News mail importing/exporting when importing from a streaming source and exporting to other sites.

Because this complex design of simultaneous import and export, there was a built-in 5 second delay between message import and waiting for the completion of the message export distribution to other sites.

If you are not hosting UUCP mail for any other site, and predominately are using wcMAIL for email and/or importing NEWS mail with no exporting, then you may use this undocumented registry setting to change the built-in 5 second delay:

Using the Windows Registry Editor, go to the folder location:

\hkey_current_user\software\msi\wildcat\wcmail

In wcMail, add a DWORD value called:

InterMessageTimeout

This value is in milliseconds.

When this item is not found by wcMAIL, the default value is 5000 milliseconds (5 seconds).

NOTES:

DO NOT SET IT TO ZERO (0)!
You might disable the ability for wcMail catch a shutdown request and you will certainly make wcMAIL become a CPU hog even when there is no mail to import.
It must be NO LOWER than 14 milliseconds which is the minimum time slice (QUANTUM) residence time for threads on Windows. (Actually the minimum quantum time for NT is 10 ms and 14-15 for 95 type systems. Anything lower than the machine quantum is essentially 0 time which tells the OS to switch threads too many times thus creating a high context switching overhead. DO NOT MAKE THIS VALUE BELOW 14.

RECOMMENDATION: Try something between 75-250.

Change it to some between 75-250 milliseconds for fast importing.

Example, 1000 will be 1 second per message. 250 will be approximately 4 messages per second.

To check the actual import rate, look at the wcmail log entries time stamps.
