Ted Ross created DISPATCH-511:
---------------------------------
Summary: Remove performance problems from locks and memory
allocation
Key: DISPATCH-511
URL: https://issues.apache.org/jira/browse/DISPATCH-511
Project: Qpid Dispatch
Issue Type: Improvement
Components: Container
Reporter: Ted Ross
Assignee: Ted Ross
Fix For: 0.7.0
There are a number of performance issues with locks and memory pooling:
- Locks are not allocated on cache-line boundaries and suffer from
false-sharing issues.
- The extra lock checks (checking the acquired state) cause significant
overhead. These should be removed.
- Pooled memory objects are not cache-line aligned and suffer from
false-sharing
- Memory pool statistics are useful but costly from a performance standpoint.
These should be able to be optionally disabled.
