With Boost.Pool you can, for example, accelerate memory ... Websysctl net.core.rmem_max. You can set the maximum buffer size you can use by: sysctl -w net.core.rmem_max=8388608. You can also set the buffer size at run-time (not exceeding the max above) by using setsockopt and changing SO_RCVBUF. You can see the buffer level by looking at /proc/net/udp.
