Emacs taking long long time for M-x memory-report

Emacs taking long long time for M-x memory-report

[Jean Louis]

I am observing that M-x memory-report is notw taking long time, like
more than 3 minutes. It did not finish yet while I am writing this.

What should I do to discover where is the problem?

It failed first time. I have just seen split window open without any
information. There was message "Quit".

It seems that I got memory or swapping problem again. I am using
master.

P.S. This is one of situations where I need to use Zile or Vi as
invoking new instance of Emacs would be very slow, it would take
minutes.

In background, on second invokation of M-x memory-report, I can still
see "Gathering data..." it is gathering data for several minutes.

Is there anything I can do to provide information so that developers
may debug it?

Profile it.  (And it isn't necessarily "a problem".)

OK. I did profiler-start. Will it work if I press Ctrl-g?

It does not exit from memory-report no matter how long I keep it. But
I did not test more than 1 hour.

It looks like my read-from-buffer which edits buffer only is taking much.

Re: Emacs taking long long time for M-x memory-report

from the event.
