I do POC for MSSQL to MSSQL replication using RS 12.6. I
have a stored proc to run testing by update value of 100
records such as "round 1000" is to update numeric value from
0 to 1000 in 100 rows. This process make database go lager
and slow while running stored proc. Compare to without
RepAgent, we use about 1 min to finish update. When we set
RA, it use about 15 mins to end replication process.

Anyone please suggest me how to solve this problem for such
a case. Thank you very much in advance.
