Priority: P2
Bug ID: 53815
Assignee: [email protected]
Summary: FileServer synchronisation is rather crude
Severity: enhancement
Classification: Unclassified
OS: All
Reporter: [email protected]
Hardware: All
Status: NEW
Version: unspecified
Component: Main
Product: JMeter
FileServer needs to be synchronised to provide thread-safety.
However, the synchronisation is applied at instance level.
This is unnecessary for at least part of the time.
The files Map is mostly read, not written, so could be protected using
read/write locks. A Concurrent Map would not be sufficient here, as the updates
need exclusive access.
Access to a single FileEntry instance would still need to be single-threaded to
prevent problems when sharing a file across multiple threads.
Making such changes should improve performance by reducing lock waits.
