Description

When I run SaveAsWebp() on my dev machine.. 300ms

When I run on an Azure App service (1cpu/1.75GB mem) it takes 6-7 seconds. Jpg encoder is fast on App service

image.SaveAsWebp(memoryStream, new WebpEncoder() { Quality = quality, Method = WebpEncodingMethod.BestQuality, FileFormat = WebpFileFormatType.Lossy, });

Is there some additional IO that could be stalling the process? seems weird its only happening for webp.

Interested to hear your thoughts!

Steps to Reproduce

deploy simple app that calls SaveAsWebp() on azure app service.

@HappyCatKitten do you know what CPU's are used in Azure App service? Do they support hardware intrinsics like SSE2 or AVX2? If not, that could be the cause of the difference.

The other thing is, BestQuality is actually expected to be slow. You should only use this method, if encoding times does not really matter. The encoding is actually done multiple times with different strategies and then the best (= the one with the least amount of bytes is picked). Maybe trying the Default encoding method would be worth a try.
