[zeromq-dev] 0MQ Tests on Linux Real-Time Kernel

[Steven McCoy]

Is the performance hit similar across SUSE Real Time, Red Hat 5.2 MRG, and
Ubuntu RT kernels?  Is this the standard Linux RT overhead or are there
distribution specific optimisations?

Red Hat is on slightly newer 2.6.24.7, but you can see the real time green
curve lags above the stock red in their graph of results:
