[Tile-serving] Fwd: Mysterious mod_tile/mapnik bottleneck seems to be in save_as_png8

[Peter Devoy]

Hi all

I am setting up a tile server and with all layers disabled am getting
TTFB latencies from 2ms all the way up to 600ms.

Might anyone know why this is please?  I have posted some details in
the help section:

Kind regards
