We now call tcp_ack() much more frequently, for some workloads this brings in enough cache line misses to become noticeable. We could possibly still kill HP provided we find a different way to suppress unneeded tcp_ack, but given we're late in the cycle it seems preferable to revert. ==================== Signed-off-by: David S.
