[AccessD] Replication - A2K

Why would the replication slow things down?  The FE/BE running locally
speeds things up by a factor of two.  Replication simply allows me to run
the BE/FE locally on every machine.

Just out of curiousity, what all have you tried to speed things up?  It
sounds like you want to replicate a database to run 'locally' on everyone's
machine.  I would be willing to be that would slow things down on it's own,
even if the db is running locally.

Are all of the users on a LAN, or are some accessing this through a VPN?  In
that case I could see replication being used.

I need any info / experiences anyone can share re replication.  My insurance
client has a functioning database now that is SLOOOOOooooow.  They came from
a "flat file" where they had basically a single table with 125+ fields to a
fully relational FE/BE with of course much expanded functionality - and of
course the speed isn't anywhere close to the same as the old.  No matter how
you explain, the user doesn't know what goes on behind the scenes, and
doesn't care.  All they know is that it is slower.  Plus they are adding
more employees (up to about 25 now from under 20 when I started the
project - and still climbing).

They will probably go to SQl Server someday but now is not the time (money).
I have been discussing options with them and explained to the tech contact
the idea behind replication.  He has been running a FE / BE development copy
of the db on his desktop and it is about twice as fast.  Therefore he thinks
that replication might solve their speed issues for the short term (for a
year or so) until such time as they could make the move to SQL Server.

So I need info.  I have done replication one time, just on my own system,
just to see how it worked - and that was a long time ago.  So I need to
start a thread with anyone who has current experience on how to set it up,
what is involved, any good reference material to read, would it work to
merge the BE/FE back in and also replicate design changes, etc.

Anyone with info out there?

Thanks,
