Appreciate any pointers on what to look for troubleshooting this perf issue. The mirrormaker maker logs looks clean and don't show any obvious issues.

We compare the transfer rate between these 2 systems with a scp transfer rate. When these 2 systems where in the same data centre the scp rate matched with mirrormaker transfer rate (around 150 MB/s). But when one of these systems was moved to a geographically distant datacenter, we see that the mirrormaker transfer rate (almost 1 MB/s) is way behind the scp rate (80 MB/s) . We tried to tune the send.buffers and receive.buffers in the mirror maker but still no effect. Any suggestions. -Rajesh
