Before I start digging into the kernel-options for my distro does anyone know if there's been any changes between 2.6.28 and 2.6.29 that would decrease BIND performance? I'm seeing a 55% decrease going to 2.6.29. /Jonathan 2009/4/30 JINMEI Tatuya / 神明達哉 : > At Thu, 30 Apr 2009 15:41:03 -0700, > J

Scale BIND over multiple kernels effectively

2009-04-30 Thread Jonathan Petersson
Hi all, I've been running some dnsperf tests on a couple of servers I have resulting in some interesting behaviors. The test-bed that I have is 3 servers with the following CPUs: E3110 (DC @ 3.00GHz), i7 920 (QC 2...@3.20ghz) and E5520 (Dual QC @ 2.27GHz), RAM is 6GB on each running at 800-1.6GHz
