My sources at ISC tell me that thread performance with 9.3.x on all platforms is worse than without threads. Enabling threads by default was a combination of a misunderstanding on my part, and a desire to shake out some of the issues related to both our threads, and the BIND code. Now that we know (most of) the answers, with 6-release coming, and BIND 9.4 not coming in time, this was the right way to go. > BTW, we saw "huge" performance increase when switched to FreeBSD > 5-STABLE (around 5.3, or 5.4, don't know exactly) and from bind 9.2.x to > 9.3.1. If you were using BIND 9.2.x previously, that is to be expected. 9.3.x has some performance improvements over the old BIND 9 code, but as you pointed out the 9.4.x code base will be a substantial improvement, focused primarily on performance issues. hth, Doug PS, thanks to Dag-Erling for the help on this one. -- This .signature sanitized for your protection
