> Project: Ignite
> Issue Type: Improvement

> Reporter: Pavel Tupitsyn

> Priority: Major
> Labels: .NET
> Fix For: 3.0, 2.10
>
>
> 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.
