Rejean,

>What is the maximum connection for LDM ?

There is no specific limit as far as the LDM code is concerned.  In
practice, however, the number of sites that a machine will be able to
feed is a function of a number of factors:

o CPU speed
o system RAM
o network connection (speed how distant the sites are)
o non-LDM server load
o volume of data to be fed to sites
o number of products in the data to be fed

There is no specific formula to determine how many sites can be fed
from a single host, but for high volume datasets a practical limit
of 20-30 can be expected.  The same hardware can feed substantially
more sites with lower volume datasets.

I hope that this helps...
