Good afternoon,

The he.wikipedia community would like to use custom image sizes for thumbnails and galleries.

This configuration change would require the creation of 250px and 200px pictures.

Hashar have expressed concern on the relevant bug* this change, with two different sizes, would cost have a cost in processing power.

I would like to know if someone has a way to measure the ImageMagick thumbnails generation cost for he.wikipedia, and more generally, if we have somewhere a page with the information "who to contact about a performance issue?" (and if not, it would be a good idea to create it).
