#15418: Performance drop 60 times on non-profiling binary -------------------------------------+------------------------------------- Reporter: hth313 | Owner: (none) Type: bug | Status: new Priority: high | Milestone: 8.6.1 Component: Runtime System | Version: 8.4.3 Resolution: | Keywords: Operating System: MacOS X | Architecture: x86_64 Type of failure: Runtime | (amd64) performance bug | Test Case: Blocked By: | Blocking: Related Tickets: #14414, #9599 | Differential Rev(s): Wiki Page: | -------------------------------------+------------------------------------- Comment (by George): I think without a reduced test case with source this will be very hard to fix. It would be interesting to see if you can reproduce the issue in the related tickets above as I don't believe others have been able to. Others will probably have suggestions about what you can do on your side.
