54315 Mails, 509M as mbox (TMP), 572M as maildir (TMP.d).
Just opening the folder (to compare with the later times):
time mutt -f=TMP.d -e "set header_cache=''" -e "push <quit>"
4.890u 2.297s 0:11.33 63.3% 676+35932k 0+0io 0pf+0w
4.936u 2.288s 0:11.60 62.1% 690+36235k 0+0io 0pf+0w
time mutt -f=TMP.d -e "push <quit>" (cache deleted)
6.453u 2.953s 0:15.60 60.2% 656+35618k 0+456io 0pf+0w
6.490u 2.984s 0:15.85 59.7% 685+36699k 0+427io 0pf+0w
time mutt -f=TMP.d -e "push <quit>" (with cache 31M)
2.571u 0.468s 0:06.26 48.4% 673+32827k 0+12io 0pf+0w
2.583u 0.469s 0:06.47 46.9% 629+32167k 0+12io 0pf+0w
time mutt -f=TMP -e "push <quit>"
3.899u 1.447s 0:14.93 35.6% 676+31507k 4828+0io 0pf+0w
3.933u 0.794s 0:07.02 67.2% 662+30678k 0+0io 0pf+0w
And now marking the mails as replied to (before the first run, 7
where marked as replied to, the second run left the folder unchanged).
time mutt -f=TMP.d -e "push
'<tag-pattern>.*<enter><tag-prefix><set-flag>r<quit>'"
3.065u 2.846s 0:12.29 48.0% 687+44545k 2531+18io 0pf+0w
2.625u 0.439s 0:06.29 48.4% 699+33973k 0+12io 0pf+0w
time mutt -f=TMP -e "push '<tag-pattern>.*<enter><tag-prefix><set-flag>r<quit>'"
6.944u 10.649s 2:15.71 12.9% 677+51075k 15435+16376io 5pf+0w
