How fast is QuickFix ?
In my firm we are beginning a new OMS (Order Management System) project and there is a debate whether we use Quickfix or we go for a professional fix engine? Because there is a common doubt that QuickFix is not enough fast and obviously we will not get any technical support. I heard that in BOVESPA it has been used for a while. They are changing it with a paid one now. Well that is enough for me. If they use it I can use it.
Should I choose a professional one over QuickFix? Is it not good enough?
In order to answer your question (for you) you would need something to compare to. You would need numbers to know if it is slower/faster, how much, and if it will impact your system overall. Also knowing your performance goals could narrow down the options.
My advice is to take a look at your overall architecture of the sytem you have or intend to build. To just look at QuickFIX is rather meaningless without the whole chain involved in processing information and reacting to it. As an example, say QuickFIX is 100 times faster than some part (in the chain of processing) you have or build. Now, replacing QuickFIX with another part which is 100 times faster than QuickFIX would not change anything because you're still held back by the slowest point. And remember that network hops are usually very expensive compared to in-memory processing of data.
If you for some reason cannot compare different candidates against each other, why not start with e.g. QuickFIX, but make the system in such a way that it can be replaced with something faster later on.
Generally speaking, QuickFIX is not the fastest option, but the key point is that it might not have to be. If performance is very critical and one has resources, you usually end up buying something or building something yourself. Drawbacks here are having resources like time, money and skilled people.
To answer your question better one would need to know other aspects as well, like available resources (money, time, skill), overall system overview, performance expectations and other factors that limit decisions. E.g. if money is not a limiting factor, just find the fastest option and buy it.
