python - Fastest way to produce UDP packets -

-

We are creating a test born to push binary messages on UDP multicast.

The prototype is using twisted reactor loops to push out the message, which is achieving the level of traffic we expect - about 120000 messages per second.

We have 16 cores on our testing machine, and obviously I really want to spread it over the core to make a horn fly.

Does anybody have any idea about how we can make the application architect (either using an event loop approach or CSP style approach) output.

Apart from this, prototype is spent mostly in writing UDP - like IO, I should not be surprised, but am I not missing anything?

Any thoughts are welcome. I have a broad NIC, hardware or kernel interface limit. I use Broadcom Corporation Net Extreme BCM5704S Gigabit Ethernet Adapter. I can only access 69,000 packets per second. Try Quad Intel Gigabit Server Adapter with all four NICs on the same subnet.

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
