This benchmarks tests the meta2 part of the object creation process, by registering fake chunks.
Track (and display) average time spent by meta2 worker threads waiting for a database handle. The purpose of this modification is to provide better warning messages when the load on a meta2 database is increasing.
Save some performance data in the thread local data. This is disabled by default, can be enabled for each service (even when the service is running) or per request. Performance data is printed at the end of access log messages.
