Hi Oleg, Some general advice:
- don't optimize code until you need to, measure before and after. - zero copy is not useful on small messages - don't pass pointers around - read the Guide and learn by making simple designs first - again, don't optimize or try to make designs faster until you really need to -Pieter On Sat, May 11, 2013 at 4:27 AM, Oleg Vazhnev <[email protected]> wrote: > Hi, > > In my financial software I receive quotes from stock exchange.
