A library for parsing FIX (Financial Information eXchange) protocol messages.
FullFIX is a library for parsing Financial Information eXchange (FIX) messages.
The main goal of the project is to produce the fastest software solution for FIX protocol.
The library is written entirely in C for better portability.
The parser depends on libc only and it does not impose any I/O or threading model.
Unlike some other well known solutions, in this parser the FIX specification
gets converted to efficient C code at compile time to achieve the best performance.
Supported FIX protocol versions: up to and including version 4.4.
The numbers below have been achieved on Intel Core i5-8500T 2.10GHz processor.
On modern production hardware the results will probably be better.
Compiler: gcc (Ubuntu 7.3.0-27ubuntu1~18.04) 7.3.0
OS: Linux Mint 19 64bit
| FIX message type | FIX specification | Validation | Average time to parse one message |
|---|---|---|---|
| NewOrderSingle(‘D’) | Hand-coded spec. for this message only | No | 0.152 µs/msg |
| NewOrderSingle(‘D’) | Hand-coded spec. for this message only | Yes | 0.262 µs/msg |
| NewOrderSingle(‘D’) | Compiled full spec. for FIX.4.4 | Yes | 0.324 µs/msg |
| MarketDataIncrementalRefresh(‘X’) | Hand-coded spec. for this message only | Yes | 0.487 µs/msg |
| MarketDataIncrementalRefresh(‘X’) | Compiled full spec. for FIX.4.4 | Yes | 0.611 µs/msg |
