Description
I noticed a sharp decline in the performance of my application when I upgraded from Camel 2.7.3 to 2.8.1. I discovered that the splitter/aggregator had become the bottleneck in my app. I have created a sample app that demonstrates the issue. The aggregator uses a lock, and I suspect lock contention may be at the root of this, but didn't notice any changes around that in the code diff between the versions.
I uploaded the sample app to http://www.vancameron.net/CamelPerf.zip. It uses gradle. Unzip to a directory then run "gradle" from the command line. To change the version from 2.8.1 to 2.7.3, edit the build.gradle file and run again.
The app loads 10 files with 100k lines each. It prints the current time in msec per batch.
