Hello,
Last time I did a bootstrap of the trunk for MS-Windows (9 days ago,
with "mingw32-make -j4 bootstrap"), it took on my laptop about 14/15
minutes to complete.
I've just done this again (with the current trunk), and it has taken
"00h49m28.682s" (?!)
Do you also observe this slow down? What's the reason for this?

Did you use -j4 or -j2 last time? Using too many simultaneous jobs
can actually slow down the build, although 3-fold slowdown sounds
gross.

No, I still get my 6 to 7 min (with -j8 on Core i7).

Did you update your anti-virus software, perhaps? Or any other
system-wide updates? Look in the system logs (a.k.a. "Event Viewer"),
under "Application" and "System" for clues.

I used also -j4 last time, but ISTR that -j5 or -j2 gave similar
results (approx. 50% of the time without -jN). That seems right,
since my CPU (Core i5-2410M) has two cores [1].

I think I've installed the usual automatic updates, but nothing more.

Thanks, I'll what I can do.

see
After turning off the "real time protection" setting in the "Microsoft
Security Essentials" application, the bootstrap time is now better:
"00h25m56.717s".
I'll play a bit more with its settings and see if I can recover the
original 14/15 minutes.
Thank you.

For the record: after doing some experiments, the major factor for the
slowness I saw was the active "power scheme" of my laptop: if I set a
high-performance scheme, I'm able to bootstrap in 14/15 minutes, but
with a energy-saver scheme, that time increases a lot.
Thanks Eli for your help.
