This patch is wonderful! When I try to migrate from dummy net shaper to ng_car on my IPOE server I faced problem that if I have a lot of CAR nodes and start to transmit even small traffic - I see CPU peak about 50-60%. It's was terrible! Good for me that I asked Glebius about it and he made this patch. Now CPU load about 1-2% with 500m policed traffic and this is GREAT! Thanks a lot Glebius!
