This was a regression caused + by the new config processor, which did no longer properly enable msg + locking in multithreaded cases. The bugfix is actually a refactoring of + the msg locking code - we no longer do unlocked operations, as the use + case for it has mostly gone away. It is potentially possible only at + very low-end systems, and there the small additional overhead of doing + the locking does not really hurt. Instead, the removal of that + capability can actually slightly improve performance in common cases, + as the code path is smaller and requires slightly less memory writes. + That probably outperforms the extra locking overhead (which in the + low-end case always happens in user space, without need for kernel + support as we can always directly aquire the lock - there is no + contention at all). --------------------------------------------------------------------------- Version 7.3.4 [devel] 2012-11-23 - further (and rather drastically) improved disk queue performance @@ -210,7 +225,6 @@ Version 7.1.12 [beta] 2012-10-18 This happened only under some circumstances.
