When I wrote to you in the last message i really meant to say that we will have a new release with some script modification to the replications it is out now for download build 4362.
Is the destination server the same system or slower (RAID array, cpu....)? Also try setting the replication bandwith to 25MB and test if you are getting the same speeds with this setting and the new version then send in the logs to pre-sales@open-e.com (please use the user portal if you have a registered product as this will help you faster) and we will take a look at them.
