The Chronicle Logger consumes 100% CPU (all 40 vCPUs are busy, synchronization is done with CAS) while Log4JLoggerBenchmark only consumes 15% CPU.
The Chronicle Logger allocates around 0.65 GB of heap when the benchmark is executed. Log4J needs much more memory and allocated over 3 GB in the benchmark.
