All the hardware is the same. Queryperf was run on a FreeBSD 6.1 box. Both boxes are connected through a Cisco switch. All connections are gig, full duplex. Test was done with changing the OS on the DNS server box. Zone data is a small zone of 256 hosts. queryperf command is: queryperf -s dnstest -d small.dat -q 40 -l 60 > I've posted some results months ago and they were kind different. > > I have done some tests [1] [2] with bind and queryperf and my result > on FreeBSD 6.1 was very poor if compared with 4.11. > > Besides this, I have had bad results with NSD + 6.1 too and it doesn't > use threads.

A task on the list but which I haven't gotten to yet. The results are interesting. I would also take them with a grain of salt. This was done very quickly to see what initial numbers would pop out. Version of FreeBSD is 6.1. named was compiled with threads and using libthr. Polling was not enabled. query OS named OS qps ------------------------------ FreeBSD FreeBSD 38442 Linux FreeBSD 22211 Linux Linux 53225 FreeBSD 4.11 is not easily installed on these boxes and currently means that I have to physically touch them so I do not know when I will have time to try it out as a query host. -- DaveD
