The first link is shared through the Gateway hosted in Europe.
The second link is shared through the Asia Gateway - it is expected to be slower if you download it from another continent.
The higher number of pieces is due to using a smaller part/segment size for upload. If you used the new web-based file browser, it is currently configured to use 5MB part size. This is suboptimal. With the next deployment, it will be reconfigured to use the optimal 64MB part size.
Now with the EU-link it is running much much better.
But why am I offered the ap-link only? Wouldn’t it make sense to inform the user that there are more regions available he can use the link on to get best performance from?
No I have the account on ap1, so it is fine. But there was no indication that I can use the share with additional regions as well.
Especially for sharing use cases it would be vital to pass a link with a good performance.
