I don't think this is new at all, but I just tried to do a perf
record/report of "make -j64 test" on git:
It's a big perf.data file (1.6G), but after it has done the
"processing time ordered events" thing it results in:
┌─Warning:───────────────────────────────────┐
│Processed 8672030 events and lost 71 chunks!│
│Check IO/CPU overload! │
│ │
│ │
│Press any key... │
└────────────────────────────────────────────┘
and then it just hangs using 100% CPU time. Pressing any key doesn't
do anything.
It may well still be *doing* something, and maybe it will come back
some day with results. But it sure doesn't show any indication that it
will.
Try this (in a current git source tree: note, by "git" I actually mean
git itself, not some random git repository)::
perf record -g -e cycles:pp make -j64 test >& out
perf report
maybe you can reproduce it.
