Hi Remco, Instrumentation is often used as an aid in performance analysis, so we felt that enabling it by default would offer several benefits with near-zero cost:
- Immediate data to analyze performance; no need to enable a test flag and re-run the operation to collect data. - Default instrumentation log size is 25 MB, so "out of the box", so no need to worry about unchecked growth. - Since instrumentation only keeps track of a set of counters at run-time, there is no meaningful impact on performance. - We also enhanced it by "promoting" the test flag to a formal option, and allowing you to change the log file name and maximum size. Are there any particular issues of concern that always-on instrumentation is causing?
