Slow data loads when taking serverrelativeurl for attachment files

Hi Guys,

I'm Having an issue when i want to add attachment links to my visuals using the AttachmentFiles tables and expand it to ServerRelativeUrl, however once i add the table all the query and data loads turns so slow, approx. only 20Kb/s.

I only had <2000 Rows in my sharepoint list with not all the rows has attachments.

Is there any ways to solve this issue or is it the usual behaviour whenever we want to use attachment in Power BI?

Thanks in Advance!
