Description Satyam Kandula CLA 2012-01-18 06:08:59 EST 
There is a huge regression (~300%) in this test (FileSystemPerformanceTest#testPutFileInfo) on one of the windows box. On the other machine the degradation is not consistent and hence this could be a noise. However, as the regression is huge, I am filing this bug.

Wow :-)
Comment 2 John Arthorne CLA 2012-01-18 13:20:04 EST 
This is surely a test machine problem. From the latest map files I can see none of this code has changed since October 2011, and the native implementation of putFileInfo hasn't changed since April 2011:

plugin@org.eclipse.core.filesystem=GIT,tag=v20111018-1451
fragment@org.eclipse.core.filesystem.win32.x86=GIT,tag=v20110423-0524

What build did this regression start in?
Comment 3 Satyam Kandula CLA 2012-01-18 23:18:10 EST 
This could have started some time around the last week of December.

Kim, could we re-run these tests?

Which build is this test associated with?

Performance results for N20120121-2000 are good. Hence, resolving.
