[openamq-dev] Topic Vs Direct Exchanges

[Martin Sustrik]

Malinga,

The design of topic exchange is such that its performance should be 
exactly equal to the performance of direct exchange. However, the 
performance is achieved on the expense of memory usage. So basically, if 
you'll switch to topic exchange, latency stays the same but memory 
footprint increases.

You can try using headers exchange if you would like to trade some 
latency for lower memory usage.
