Subject: Bump the mempool sizes in dns_message
X-Git-Tag: v9.19.18~12^2
X-Git-Url: http://git.ipfire.org/gitweb.cgi?a=commitdiff_plain;h=c855ed6a0b50fe742a17d42130ad6ecaf1db72ad;p=thirdparty%2Fbind9.git

Bump the mempool sizes in dns_message

Increasing the initial and freemax sizes for dns_message memory pools
restores the root zone performance.  The former sizes were suited for
per-dns_message memory pools and we need to bump the sizes up for
per-thread memory pools.
