3.2.0
87499f6

In addition to a couple of bug fixes, this version modifies page run allocation and dirty page purging algorithms in order to better control page-level virtual memory fragmentation.

Incompatible changes:

  • Change the "opt.lg_dirty_mult" default from 5 to 3 (32:1 to 8:1).

Bug fixes:

  • Fix dss/mmap allocation precedence code to use recyclable mmap memory only
    after primary dss allocation fails.
  • Fix deadlock in the "arenas.purge" mallctl. This regression was introduced
    in 3.1.0 by the addition of the "arena.<i>.purge" mallctl.
