> Camel 3.x as well as 4.0.0-M1 reportedly have multiple cases of the
> type-check scalability described in [this
> post|https://redhatperf.github.io/post/type-check-scalability-issue/].
> This can affect the the scalability of Camel when running with multiple
> threads and incur in extra unnecessary work.
> See the attachment [^sample-trace-for-m1.txt] for a report of the possible
> cases for M1 (triggered by running a simple application using seda).
> The initial set of patches for CAMEL-15105 have helped a great deal to remove
> these, but there's still a few to resolve.
