Strange performance issue with Storage

[jannone]

When running a simple script that responds an HTTP request with tableService.insertOrReplaceEntity, on a single core machine (Azure), my maximum throughput is just 48 req/sec, with the CPU at 10% (in other words, CPU is very idle).

When running the same script under node-cluster, in the same single core machine but now with 4 node processes, throughput reaches 134 req/sec.

Issue 1 - Is Azure SDK for node really 100% asynchronous? This data seems to indicate it is not, but I can't verify. node-cluster should not make a difference, since this is a single core machine.

Issue 2 - Even with node-cluster, throughput is too low, since the Azure documentation indicates a limit of 2000 entities per second in a single partition. Why?

#1230

Hey guys, sorry to bother, but what is the duplicate issue? Has this been fixed?

Thanks.
