[zeromq-dev] Effect of compiler-performed optimisation on the performance

[Martin Sustrik]

Hi all,

We've tested the impact of different compilers and optimisation levels 
on 0MQ performance. The whitepaper can be found here:

http://www.zeromq.org/results:compiler

The summary:

"As for latency, optimisation can improve it by 5 microseconds, which is 
not that much, however, for ultra-low-latency applications it may prove 
to provide some benefit."

"As for throughput, the most improvement can be gained for messages up 
to 128 bytes. For reasonable sized messages (stock quotes) the 
improvement can get up as high as 35%."

Cheers.
Martin
