OK Folks - here's a weird one that PROBABLY falls into the category of mere
coincidence, but I'm sending it along anyway...
We have several IMail (5.09) domains on our server, with user accounts
directed via ODBC to SQL 6.5. ONE of the hosted domains was originally set
up using the "native" IMail user database, the rest all go through SQL.
Users of the one "IMail native database" domain complain that their mail
uploads & downloads (typically including 1.5 MB attachments) take FAR longer
on our system, than they experience using alternative mail systems (e.g.,
AOL or EarthLink) from the same PCs. No other client domains are
experiencing this sluggish response.
I've tried looking at basic circuit "cleanliness" and backbone connection
speed, but find no performance bottlenecks there.
So I am wondering - is there any logical explanation for slow file
transfers, that has to do with recurring user authentication (or other IMail
user database interaction) as a download proceeds? Would migrating the
rogue domain to SQL make a difference? (I plan on converting the users to
SQL 6.5 eventually ANYWAY, but the pace at which this occurs hinges on
whether or not performance is affected).
Anyone have insight to this issue?
