Receive Buffers
Under certain conditions the host PC system CPU may be busy with tasks other than the
imaging application. Incoming image packets remain in the PC memory allocated to store
packets instead of immediately being copied into the image buffer. By increasing the
number of NIC (network interface card) receive buffers, more incoming image packets
can be stored by the NIC before it must start discarding them. This provides more time
for the PC to switch tasks and move image packets to the image buffer.
Not all network boards allow increases to their receive buffer count. Among those that
do, different versions will have different maximum receive descriptor values.
We recommend increasing the receive buffer size to the maximum permitted by the
network card, in order to provide more buffering capacity when needed.
