Without information about the particular images - the data set you're working with - it's hard to provide any accurate advice. If the images are small, maybe it's all overhead. If the images are of a particular form of PNG, maybe a fast path is missing. And so on.
To get meaningful help for problems like this, the more information you can provide, the better. -rob On Fri, Jun 26, 2020 at 10:59 PM Lee Armstrong <l...@pinkfroot.com> wrote: > Thanks, I am already maxing out some servers but wondered if it could be > sped up. > > I will give the bimg package a go! > > On Friday, June 26, 2020 at 1:55:40 PM UTC+1 ren...@ix.netcom.com wrote: > >> Just parallelize in the cloud.
