Summary: .NET: Performance: review
CopyOnWriteConcurrentDictionary.GetOrAdd usage and locking
Key: IGNITE-12414
URL: https://issues.apache.org/jira/browse/IGNITE-12414
Project: Ignite
Issue Type: Improvement
Components: platforms
Reporter: Pavel Tupitsyn
Assignee: Pavel Tupitsyn
Fix For: 3.0, 2.9
CopyOnWriteConcurrentDictionary.GetOrAdd uses lock right away, while the class
assumes frequent reads and infrequent writes. It can be beneficial to check for
the key outside of the lock.
In particular, this often causes contention because of
BinarySystemHandlers.GetWriteHandler call.
Review other usages of this method.
