Hi
I just pushed some commits that improves a little bit the startup of
Apache Camel. The Caffeine LRUCache will upon initialization block for
150 - 200 millis, which we can do in parallel while Camel is being
started. Before this initialization was always forced when you created
a new instance of
Hi
I found some other rooms for optimisations such as
- invoking the base of the core type converters faster
- jmx mbean of processors in the routes is using advice over wrapped
processor to reduce garbage collection
- simple language now caches evaluated expressions/predicates which
yields faster
Hi
Just a little status update, that after a bunch of different
optimisations, then the YourKit profiler is now down to showing that
the type converter registry and the uuid generator is potential
hot-spots, where the former is used a lot and we can optimise the
conversions for the core converters

I just added our first JMH tests, which you can find in the
tests/camel-jmh
Hi
Just a heads up that I have been in contact with YourKit about
licenses for their tool for Apache Camel committers.
They got back to me and we have a project wide license that can hold
10 installed copies. I have installed one so there is 9 left.
Anyone whom is helping with this work of work

A candidate for JMH micro benchmark would be the

Hi
So today the old cruft of the legacy tracer came to bit us. There is
something called Tracer in camel-core that was used to trace Camel
messages. Its only in use if you do camelContext.setTracing(true) from
Camel end users point of view. However it captures trace details
regardless.

Yeah we can try that.

It may be worth adding a small number of JMH micro benchmarks - not to
be used as performances metrics - on camel core so we can spot
potential regressions.

Hi
I have found some more spots for optimisations which I have committed
over the last couple of days.
Its been several years since we last did such things last, and I have
to admit we have introduced some code that add more object allocation
and a few performance drawbacks since then.
So with t

Hi,
awesome work Claus :)
Just to add that you can do a lot with just VisualVM (bundled with
JDK), or if you run Oracle JDK Mission Control/Java Flight Recorder
which does not require a license when used in development[1].
And let me throw a few things into the mix: there is a great tool for

Hi
We have found a few spots to optimize the camel-core source code for
thread contention and something else.
You can use a profile tool such as YourKit which is excellent at
identifying spots and visualizing what goes on in the JVM.
We have used it in the past to optimise stuff. However recentl
