`system_clock` seems to get better results than `steady_clock`
namespace dmtr {
class rdma_queue : public io_queue {
- public: typedef boost::chrono::steady_clock clock_type;
+ public: typedef boost::chrono::system_clock clock_type;
public: typedef boost::chrono::duration<int32_t, boost::milli> duration_type;
private: static const size_t recv_buf_count;
