Adaptive interrupt moderation

摘要

Generally, this disclosure relates to adaptive interrupt moderation. A method may include determining, by a host device, a number of connections between the host device and one or more link partners based, at least in part, on a connection identifier associated with each connection; determining, by the host device, a new interrupt rate based at least in part on a number of connections; updating, by the host device, an interrupt moderation timer with a value related to the new interrupt rate; and configuring the interrupt moderation timer to allow interrupts to occur at the new interrupt rate.

1. A method comprising:
determining, by a host device, a number of connections between the host device and one or more link partners based on, at least in part, a connection identifier for each connection; determining, by the host device, a new interrupt rate based at least in part on a number of connections; updating, by the host device, an interrupt moderation timer with a value related to the new interrupt rate, and; configuring the interrupt moderation timer to cause interrupts to occur at the new interrupt rate; wherein:
said determining a new interrupt rate comprises comparing the number of connections to a first threshold number of connections and a second threshold number of connections that is greater than the first threshold number of connections;when said number of connections is less than said first threshold, the new interrupt rate is a first interrupt rate;when said number of connections is greater than said second threshold, the new interrupt rate is a second interrupt rate; andthe first interrupt rate is greater than the second interrupt rate.
