--------------------------------------------
Summary: camel-file: investigate performance improvements
Key: CAMEL-17559
URL: https://issues.apache.org/jira/browse/CAMEL-17559
Project: Camel
Issue Type: Improvement
Components: camel-file
Reporter: Otavio Rodolfo Piske
While working on CAMEL-15562, with a very large directory tree, I noticed that
sometimes it tends to perform a bit poorly when traversing very large directory
trees.
I think we could explore migrating some of the camel-file code to use newer
(and, sometimes better/faster) I/O APIs to improve the performance/scalability
for extreme use cases.
Simulating the way Camel works now and comparing with some alternatives,
indicates that there can be some possible performance gains (testOldIo is the
current way the code works).
