Best way to replicate huge transactions

We do nightly processing for our warehouse data on Server A and we replicate
the data after all the processing to Server B.
What is the fastest way to push this data across ? Right now it seems like
it takes more than an hour to push all the changes across.i.e an hour
latency. We are using trans replication. Any parameters we can tweak to push
the data faster or are there any other techniques.
Please advice.. Thanks
Hassan,

parameters:

|||replicate the execution of stored procedures if
1) your stored procedures modify more than one row at a time
2) the bulk of your batch operations use procs
consider using merge replication if
1) your batch operations modify the same row many times, ie a stock market
application.
2) use download only exchangetype
