Hi All Experts
Does anyone know whether having more back-ends with fewer tables performs slower/faster than say one BIG backend with all tables.

I have a number of systems with approximately 10 front-ends (for different departments/functionality etc) and 10 back-ends and always wondered if 'consolidating' the BEs would increase/decrease performance?

The multiple BE systems seem to perform OK; although they require periodic c&r (usually every 3-6 months )

Ideally this question would be answered by someone who has had similar installations over many years (or is involved in MS Access JET/ACE design and drivers)

There is always the potential of more users in the same BE (ie consolidating) having a negative impact on performance.  If each of your 10 FE are connected to their respective BE ... I would leave it alone, unless you have some overwhelming reason for consolidating, possible for reporting purposes, etc.

I currently have 45 FEs connnected 45 BEs, with anywhere from 3 to 120 users in a given db. Where as I could ... do some consolidation (and I may for very similar db functions), at this time I am not making any changes.

I agree with Joe...I'd keep them separate.   There is some consolidation of resources if a user uses more than one of the applications at one time, but if their going against one BE all the time, then forget about it.
