The style is pretty much self contained, so should be pretty quick to render. The GeoServer version is the same.... would seem to suggest the difference is somewhere else. Did you check the proxying thing you have going on? This URL is not coming from a straight GeoServer call, it even says "proxy" in it:
https://<servername>/*Server/MapServiceProxy* ?mapServiceId=eca7ca5c-f0fe-45d8-a279-747eb9bfbae6 Try making direct requests to GeoServer, without going through that proxy and possible authentication, is the timing still different?
