MDA protocol and library improvements

Apama Capital Markets Foundation Documentation : Capital Markets Foundation Release Notes : What's New in Capital Markets Foundation 5.2 : MDA protocol and library improvements

The CMF performance has been enhanced by various MDA protocol and library improvements. The following throughput and latency improvements were recorded in laboratory conditions:

Throughput (orderbook updates/second)	CMF 5.1.1	CMF 5.1.1	CMF 5.2	CMF 5.2
	1 context	4 contexts	1 context	4 contexts
Windows	3880	7140	6650 (+71%)	16400 (+130%)
Linux	4590	10160	6460 (+40%)	25580 (+151%)
Latency (orderbook milliseconds 99th percentile)	CMF 5.1.1	CMF 5.1.1	CMF 5.2	CMF 5.2
	Main context	Non-main context	Main context	Non-main context
Windows	0.82	0.87	0.60 (-27%)	0.60 (-31%)
Linux	0.81	0.85	0.60 (-26%)	0.60 (-29%)

The main/single context results show the performance improvements due to protocol and library improvements.

The non-main/multi-context results also show the performance and scaling improvements due to the use of channels.

These measurements were recorded on:

Windows machine specifications: Intel® Xeon® CPU E3-1270 V2 @ 3.50GHz 8 Cores, 16Gb RAM, Windows 7 64-bit

Linux machine specifications: Intel(R) Xeon(R) CPU E5-2690 @ 2.90GHz 32 Cores 64Gb RAM, RHEL 6 64-bit
