Hello,
since 2 days I do have a heavy perfomance issue (after a blue screen) on my Piwigo server (Windows Home Server 2011).

    Piwigo 2.9.3
    Betriebssystem: WINNT
    PHP: 7.0.5 (Info anzeigen) [2018-06-11 22:57:20]
    MySQL: 5.5.60-MariaDB [2018-06-11 22:57:20]
    Grafikbibliothek: External ImageMagick 6.9.3-8

Have in total 50.000 photos and 500 albums.
When starting i.e. an ablum of 100 photos it needs approx. 80 sec. to see the overview.

Have already checked the database (within piwigo and also with HeidiSQL).
Have de-activated all plugins (except of GThumb+) - no change.

Any hint is welcome.

Regards
kuzco
