[New-bugs-announce] [issue28006] Remove tracing overhead from the fine-grained fast opcodes
report at bugs.python.org

New submission from Raymond Hettinger:
The fast opcodes are ones where we bypass signal/event checking, but they still have the overhead of checking for tracing enabled (this doesn't seem like much, it adds a memory access and can take almost half the time for some of these already quick opcodes).
I haven't seen an effect on the upstream line level tracing but this needs a second look to be sure there isn't an unanticipated consequence.
