Remoting frameworks performance comparison...
I take a simple test for Web-services (JAX-WS, ASP.NET) and BinaryNotesMQ performance and get the following results:

Environment: Intel Core 2 Duo 6300 / 1Gb RAM.
OS: Windows XP SP2
Transaction description: There is a process that calling service with 3 input params: 1 integer, 2 string parameters (contain small length values - approximately 5 chars) and receiving return result as simple string (~approximately 10 chars).

BNMQ: 80 bytes / 20000 tps (Java 1.6/BinaryNotes v1.4, PTPSession call async style)
ASP.NET: 643 bytes/ 400 tps (ASP.NET 2.0, async web-service call)
JAX-WS: 672 bytes/ 250 tps (Java 1.5, sync web-service call)
* Packet len is specified for call packet (without return result packet size).

Performance in tps (Transactions per second):

The version 1.3 of BinaryNotes is coming...
This photo demonstrate it's difficult work. Compare it with this photo... ;)

Java6 release is available now!
Under my tests this release improved performance really up to 20-30% (BinaryNotes)

New version of BinaryNotes 1.2 is released... but 1.3 already in progress and 1.4 is planned too ... ouh...
I'm tired :)

The new version of BinaryNotes (1.1) has been released some time ago.
But the new version 1.2 with support SET,DEFAULT and DER encoding is almost ready now. ;)
Creation of BinaryNotes needs more time, but i coming soon to new project where BinaryNotes is subproject.
