Netty speed bottleneck

[frankdurden]

Hi,

I'm testing networking speed between two blades connected via 10Gbit
ethernet. My test is very simple and uses Google's Protocol Buffers to send
big messages between the machines. I'm getting a speed of ~35MBytes/sec
which is not that impressive. This is a memory to memory test, no file IO.
ttcp tells me that the speed should be at least 400MBytes/sec. So I'm
wondering where the bottleneck is, is it how I use Netty, is it Netty itself
or does it have to do with Java sockets. Can I do anything about this? Does
the 'More New I/O API' address this in anyway?
