issue with photos previes

Hi,
i might mentioned that earlier, but why piwigo doesnt generate prieview in background or faster? I am running galleries... but each time i change client web/anroid apps and i open gallery it took ages since previews of photos are generated...

is there some command to generate previews or can i speed up that proces?

thanks

piwigo only generates the sizes it needs.

If you change to a device with a different display size, then Piwigo will generate previews for it. Subsequent visits on that device should be faster.

server is pretty fast, 32G ram, 4 cores, idling most of the time.... it just takes a longtime ... no clue why. during geneation of previes the ram/cpu is not utilized to 100%

Hi Phear,

1- You may try to pre-generate derivatives, in admin mode, batch manager.
2- If you use imagemagick, you may try GD. In my opinion the IQ is the same when contemplated in a web browser and the derivative' generation is faster.
3- Then, if you load your pictures thru ftp, maybe they are too big? The biggest they are, the slower it is to generate derivatives.

Give us more infos on your setup (versions...)

Regards.
