Bug #: 52333
Summary: Consider how to reduce overhead in calculating
SampleResult#nanoTimeOffset
Product: JMeter
Version: 2.5.1
Platform: PC
OS/Version: All
Status: NEW
Severity: enhancement
Priority: P2
Component: Main
AssignedTo: [email protected]
ReportedBy: [email protected]
Classification: Unclassified
When using System.nanoTime(), the SampleResult ctors calculate the current
offset from currentTimeMillis().
This was previously done just once when the class was initialised, but this was
found to cause problems because of drift - see Bug 51855.
Consider using a background thread to calculate the offset, rather than
calculating it for each sample - this should reduce the overhead for high
sample rates. So long as the time between refreshes is kept reasonably low,
drift should not be sufficient to cause an issue.
