Hi, I'm using FreeBSD 9-STABLE on a four core machine with bce to run multi-threaded unbound with libev (using kqueue). Here's the first message (not a long thread so far) about the problem: http://unbound.net/pipermail/unbound-users/2012-February/002237.html To summarize: whether I run unbound in multi-threaded or multi-process mode, I get very bad DNS query distribution between threads/processes. There is sometimes a 10-fold difference in the queries served (QPS) between threads (for example thread X gets 300, thread Y gets 3000). What could be done to make this distribution more balanced between threads? And where does this happens exactly? Thanks,
