Ok, less confused now - it IS 27500%! That's with me single-core 900Mhz
machine. An i5 or i7 will have much better throughput me thinks, at
least the clocking...I would love to hear some numbers...it is 13 Mbs
now, in loopback; can we reach 50 Mbs?
One known issue: when calling setsockopt: (squeak protocol is
Socket>>#setOption:value:, one of the values fails. Here is the code
where Iam calling this...
ConnectionHandler>>#newListener
| listener |
self flag: #todo. "listener _ self socketClass newTCP."
listener := Socket newTCP.
listener setOption: 'SO_REUSEADDR' value: 1.
listener setOption: 'SO_LINGER' value: 0.
"backlog is how many simultaneous connections to accept at the same
time"
listener listenOn: portNumber backlogSize: 10.
^listener
The stdout/stderr output from this call is:
setsockopt: Invalid argument
setsockopt: Invalid argument
Note that I also refactored teh pipeline to eliminate a few calls,
change the protocol and rename some classes. I updated the diagram at
https://github.com/SqueakCryptographySquad/Mushroom/wiki.
There is now a version 5 of the SecureSession package in the repository.
Thanks,
Robert
