Configuration
FIX Antenna reads the configuration parameters by default from the engine.properties file during initialization.
The user can also assign another name for the configuration file, such as the V12.FIXAntenna.FixEngine.__init__() call parameter.
For example:
engine = v12.FixEngine("FE.properties")
Common parameters

# Socket outgoing buffer size
# Default value: use system defines
# Session.Default.SocketSendBufSize = 7000
# Sets the approximate time in microseconds to busy poll on a blocking receive when there is no data. (SO_BUSY_POLL, since Linux 3.11)
# Increasing this value requires CAP_NET_ADMIN. The default for this option is controlled by the /proc/sys/net/core/busy_read file.
# The value in the /proc/sys/net/core/busy_poll file determines how long select and poll will busy poll when they operate
# on sockets with SO_BUSY_POLL set and no events to report are found.
# In both cases, busy polling will only be done when the socket last received data from a network device that supports this option.
# While busy polling may improve latency of some applications, care must be taken when using it since this will increase both
# CPU utilization and power usage.
# Default value: use system defines

# Session.Default.SocketBusyPollTime = 600000
# Sets the maximum TCP segment size in bytes sent on the network. (TCP_MAXSEG)

Threads configuration
Linux
After upgrading to FIX Antenna v2.10.16 Linux users should check engine.properties file. Threads related to data sending/receiving are isolated from each other and from other tasks. Therefore two new optional settings in the engine.properties has been added:
Dispatcher.RecvWorkersCount (default = 3). Defines number of workers to handle incoming messages.
Dispatcher.SendWorkersCount (default = 1). Defines number of workers to handle outgoing messages.
Also each send/receive thread pool can operate in busy loop. Therefore two optional settings has been added to define epoll request timeout.
Dispatcher.SendWorkersTimeout (default = -1 (no busy loop)). Defines millisecond timeout to wait for readiness of the socket to send data.
Dispatcher.RecvWorkersTimeout (default = -1 (no busy loop)). Defines millisecond timeout to wait for readiness of the socket to receive data.
The meaning of the NumberOfWorkers has been changed. Now it defines number of general purpose workers. General purpose workers maintain heartbeats, reconnects, rejecting and other functionality not related to sending/receiving data.
Example
Following engine.properties settings will make FixEngine to create 5 threads. 3 threads for data processing, 1 thread to send data, 1 thread for general purpose stuffs.
Dispatcher.RecvWorkersCount = 3
Dispatcher.SendWorkersCount = 1
NumberOfWorkers = 1
Windows
On Windows number of threads which serve FIX sessions is defined by NumberOfWorkers parameter. Recommended value is 10. It is suitable for most systems. But if you application handles more than 6 sessions which actively send/receive data and your server has more than 6 CPU Cores, try to increase number of threads. Suitable parameter value should be distinguished during testing.
Monitoring parameters
Monitoring parameters are used to define the properties of administrative session. AdminSessionDef.* parameters are default session properties. AdminSession.*.* parameters are the properties of a specified session. Fix Engine uses the administrative session properties while creating a session.
