Re: [Quickfix-developers] How to suppress 35=X messages in log file

[Grant B. <gbi...@co...>]

Are you sure it's a waste of time?  Sounds like a premature-optimization
mindset.

Attempting it and profiling its performance sounds like an easier option
than hacking the engine, and I don't think it would take that many
man-hours.
