Public-Facing Changes
Description
This PR makes some minor performance improvements:
websocketpp::endpoint< connection, config >::send(connection_hdl hdl, message_ptr msg)
std::array<uint8_t, N>
to avoid heap allocationTo measure performance improvments, I wrote a test client that prints some channel statistics: foxglove/ws-protocol#361. The table below shows the average CPU time and data received (over 4 runs) when playing back
realsense-ros2-001.mcap
:We can see that this PR significantly reduces CPU load while the data throughput remains almost the same (statistically speaking probably not significantly different)
