2 seconds for 100 puts that aggregate 50mb is 20 milliseconds per put. Out of curiosity, how are you measuring the time taken for both HBase and the network latency? How many sessions are doing the PUT's? How far away is the other DC? Are the HBase connections persistent, or are you doing the full connection setup for each PUT?
What do you see if you write a simple socket server in the other DC and send it a 500kb payload (no HBase) in a loop of 100?
