The new streaming pipeline of Reflect 1.3 seems to have impressive performance when the Reflect projects are hosted locally. But if the project is hosted in the cloud there are some strange results. I have build a simple prototype with the minimum Viewer API (not the standard viewer) to directly compare 1.2 and 1.3. If the project is hosted locally, the first time it is open in 1.3, it takes between 80-70% of the of the equivalent time in 1.2. Later times the project is open in 1.3 (with local cache), it takes between 65-50% of the equivalent time of 1.2 (large models open consistently 2X faster, that is quite impressive). But if the project is hosted in the cloud, the first time it is open, it takes between 200% and 400% of the equivalent time in 1.2. Later times it will open in 85-90% of the the equivalent time in 1.2 (faster but not as much as with the project hosted locally). The comparison between 1.2 and 1.3 using projects hosted in the cloud were done immediately one after the other, so the difference cannot be explained because the cloud server were busy when using 1.3. And to avoid possible issues, the local cache folder was deleted before switching between versions.
