Dear Equinox Committers, As we've been upgrading our eclipse-based product to Luna, I wanted to validate that our startup performance is still good:
* get an *exact* measurement for the wallclosck time Eclipse takes from double clicking eclipse.exe to seeing the UI, * get activation traces, such that I can debug reasons for bundle activations that are unexpected, * get some per-bundle timing information to understand which bundles contribute most to startup time. In the past, all that was possible using -debug org.eclipse.osgi tracing options, plus Core Tools runtime spy. But it looks like ALL of the infrastructure is now broken in Luna: 1. BundleStats are no longer collected for usage in Runtime Spy - looks like this feature was just removed: https://bugs.eclipse.org/bugs/show_bug.cgi?id=412502 As a result, the Runtime Spy looks pretty much useless - there's no data in the "Runtime Spy" perspective at all even though monitoring is enabled. 2. The org.eclipse.osgi/trace/activation=true tracing option doesn't print activation stack traces to "runtime.traces" any more (is this just a bug / oversight or am I doing something wrong?) 3. The Application Started: <timestamp> output which we get with -debug -consoleLog does not seem to be accurate any more. Measuring wallclock time, Eclipse is on average 5 seconds slower than indicated by the timestamp. Reading the docs, I found a reference to the newly introduced debug/bundleTime tracing option, but I'm unsure how to interpret the data; it also seems to be very inexact and thus useless to me (getting nanosecond resolution would be good when available). Is there any new infrastructure available to get me the data I need ? How do others measure and improve startup performance ? Shall I just file defects for the regressions observed ?
