Sure. I've attached a log in which I set a breakpoint in part of the code
that is executed when the application starts up.

The worst part of the experience for me is that it takes quite a while from
when the debugger first hits a breakpoint until it's possible to see the
local variables and otherwise use the debugger (step, disable a breakpoint,
etc). In this particular case it took about 10 seconds. In the previous
attempt (not recorded in the log) with the breakpoint in the same place, it
took about 19 seconds.

After the initial slowness using the debugger is relatively quick, but
sometimes it will take 10-20 seconds when switching to a different place in
the stack or stepping in or out of a function (not demonstrated in attached
