> Project: Geode
> Issue Type: Improvement

> Priority: Major
> Fix For: 1.14.0
>
>
> It's been observed that when the number of threads used in a Geode client
> using PdxSerialization is greater than 8, there is an important drop in
> performance.
> Analysing the client process behavior with perf, it has been observed a very
> high CPU consumption by a spinlock
> (apache::geode::util::concurrent::spinlock_mutex::lock) used when accessing
> the serialization registry .
