Performance

Here comes several micro-benchmarks for trading components.

Benchmark environment is the following:

CPU architecutre: Intel(R) Core(TM) i7-4790K CPU @ 4.00GHz
CPU logical cores: 8
CPU physical cores: 4
CPU clock speed: 3.998 GHz
CPU Hyper-Threading: enabled
RAM total: 31.962 GiB
RAM free: 21.623 GiB

OS version: Microsoft Windows 8 Enterprise Edition (build 9200), 64-bit
OS bits: 64-bit
Process bits: 64-bit
Process configuaraion: release

NASDAQ ITCH handler

Benchmark measures the performance of the NASDAQ ITCH handler. It shows how fast it can parse and handle ITCH messages from the input stream.

ITCH processing...Done!

Errors: 0

Processing time: 6.831 s
Total ITCH messages: 283238832
ITCH message latency: 24 ns
ITCH message throughput: 41460256 msg/s

Market manager

Benchmark measures the performance of the Market manager. It shows how fast it can handle orders operations (add, reduce, modify, delete, execute) and build an order book.

Market manager (optimized version)

This is an optimized version of the Market manager. Optimization tricks are the following:

  • Symbols and order books are stored in fixed size pre-allocated arrays.
  • Orders are stored in the pre-allocated array instead of HashMap. This gives O(1) for all orders operations with no overhead (get, insert, update, delete).
  • Orders linked list is not maintained for price levels, just orders count.
  • Price levels are stored in sorted arrays instead of Red-Black trees. The sort order keeps best prices (best bid / best ask) at the end of arrays which gives good CPU cache locality and near to O(1) search time for orders with close to market prices, but has a penalty for orders with far from market prices!
  • Price levels are taken from the pool, which is implemented using a pre-allocated array with O(1) for create and delete each price level.

Market manager (aggressive optimized version)

This is a very aggressive optimized version of the Market manager. It shows values of latency and throughput close to optimal with the cost of some more optimization tricks which might be hard to keep in real trading platforms:

  • Symbols are not maintained
  • Orders and price limits structures are optimized to be optimal. Most of useful filds are removed.
  • Price values are stored as signed 32-bit integer values. Positive values for bids and negative values for asks.
  • Market handler is not used. No way to receive notifications from the Market manager.
