NTMail is running on a machine with 128Mb ram/P200(Just a plain old 200)
and IIS4 with a few domains. After running for a day or so, POP and SMTP
occupy about 70-90 MB of RAM by themselves, and inetinfo user another 40Mb.
It takes about 24 hours to reach these ram levels. Immediately after boot
up, only about 71 Mb (including disk cache) is in use. I believe that the
inetinfo size is due to IIS caching its web content.
Anyway, SQL is on a different server p166/96Mb RAM. When a user checks POP
mail, it takes 10-15 seconds for emer_ntm to retrieve the user info from
the DB. It almost seems like it has to login to the SQL server or
something like that. The SQL server only has about 10-15% CPU utilization
and considerable idletime on the Harddrive. It appears to just be sitting
there after the pop request has come in.
Is this performance normal with NTmail? I have a number of users
complaining that SOME of their incoming mail is bouncing back to the sender
with invalid user errors. This is only some mail. Also, when checking pop
mail sometimes users get "Invalid username/password". They can check again
a few seconds later and it works. The problem is that some users
immediately start playing with their system and screw it up. Then I spent
the next half hour trying to fix them.
Here's one for Dale.... Can you make an SQL script that will generate a
file (like radius) that can bet run with the command line ntmail program to
save the users to the ntmail registry. This will allow users to bypass the
ntmail.dll and full utlilize the aliases, etc within emerald. If this can
be done in an external program or as an SQL script, then I can schedule it
to run periodically during the day. This will reduce the loading on the
SQL server and reduce network traffic plus significantly enhance the
reliability of the NTmail server since it won't rely on the ODBC
connection... Which seems shaky at best.
Duane.
