> Depending on different systems, it can take a few seconds for mapping
> extensions but it is not clear in the logs what is happening. In the example
> below there is ~40 seconds from when all the nar files have been expanded
> until the first nar file is loaded.

> {code:java}
> 2025-09-15 13:58:51,322 INFO [main] org.apache.nifi.nar.NarUnpacker Expanding
> 111 NAR files started
> 2025-09-15 13:59:19,783 INFO [main] org.apache.nifi.nar.NarUnpacker Expanded
> 111 NAR files in 28.461 seconds (28461014222 ns)
> 2025-09-15 13:59:59,298 INFO [main] org.apache.nifi.nar.NarClassLoaders
> Loaded NAR file:
> /home/someuser/nifi-2.6.0-SNAPSHOT/./work/nar/extensions/nifi-jetty-nar-2.6.0-SNAPSHOT.nar-unpacked
> as class loader
> {code}
>
> The point of this ticket is to reposition the first two log statements above
> in order to encompass the time of mapping extensions.
