FIX Antenna C++ 2.19 Performance
Several FIX Antenna C++ configurations are tested:
- Default. It is the good quick start variant
with balanced performance and security. The configuration may
be effectively applied both to the Sender Host and the Receiver
Host.
- Optimized.balanced.onload. The Solarflare
OpenOnload technique activated within the configuration optimizes
the TCP stack. However, the configuration may be applied only
if there is a Solarflare Network interface controller installed on
the machine. It is advised to be used for the Sender Host.
- Aggressive. It is the optimized version of the
default configuration. The aggressive mode is used, so that there
are allocated two dedicated threads for each FIX session. The
configuration is advised to be used for limited amount of
sessions (say, tens, or probably, hundreds sessions) and
may be effectively applied both to the Sender Host and the Receiver
Host.
- Optimized.hard. For the latency reduction, the
affinity masks are used in the configuration. Also few
validation parameters, which are not necessary in the fully
controlled environment, were switched off. It is advised
to be used for the Sender Host.
- Optimized.hard.spin. The spinning mode is
activated in the configuration by the following
setting: Session.Default.AggressiveReceiveDelay = 0,
it forces threads to spin. It is not recommended to use the
configuration if the number of threads is significant as it is
highly consumable for the CPU. It is advised to be used for
the Sender Host.
