Message-ID: <4A43D3CC.2050405@itcare.pl> Date: Thu, 25 Jun 2009 21:45:16 +0200 From: Paweł Staszewski <pstaszewski@...are.pl> To: Linux Network Development list <netdev@...r.kernel.org> Subject: Re: weird problem Ok After this day of observation im near 100% sure that this cpu load is made by route cahce flushes When route cache increase to its "net.ipv4.route.gc_thresh" size or is near that size system is starting to drop some routes from cache then cpu load is increase from 2% to near 80% after cleaning / flush cache when cache is filling cpu load is again normal 2% Someone know how to resolve this ? on kernels < 2.6.29 i don't see this, all start after upgrade from 2.6.28 to 2.6.29 - then i try 2.6.29.1 , 2.6.29.3 and 2.6.30 and on all this kernels >= 2.6.29 problem with cpu load is the same. I can minimize this cpu fluctuations by changing of route cache /proc parameters but the best result for my router was 15 sec of 2% cpu and after 15sec of 80% cpu Regards Pawel Staszewski Paweł
