A center to collect market data from cryptocurrency exchanges and distribute it over UDS(Unix Domain Sockets) using GoEx, it design for multi-strategy in one server, especial hft(high frequency trading)
Some exchanges has limitation for REST api, limit access frequency by IP or Account.
Usually we start some strategies in one server(description followed), Exchange 2 maybe ban your server IP because too many request.
So we could use a market center as a router to avoid limitation(description followed)

- When the server and client benchmark programs run on the same box, both the TCP/IP loopback and unix domain sockets can be used. Depending on the platform, unix domain sockets can achieve around 50% more throughput than the TCP/IP loopback (on Linux for instance). The default behavior of redis-benchmark is to use the TCP/IP loopback.redis report
