Slow notebooks
I've noticed that my notebook in Microsoft Fabric has suddenly become quite slow today. Interestingly, I encountered a similar issue before, and the next day everything returned to normal without any...
I am facing the same issue when we are running notebook from fabrics It will take to much time for small operation as well. How we can improve notebook slowness in future.
in our case it was a combination of factor:
1- Cold run
2- Small semnatic model
3- Owner user of lakehouse was disabled (caused many more bad symptoms including SQL endpoint Access Denied error).
4- Too many tables in the lakehouse
5- Using custom pool instead of standard pool, which takes 3 minutes to Start
Apart from that, the notebook logic itself may require review (including if the notebook accesses multiple sources including documents in Lakeouse.
Bottom line, this requires multiple checks to answer 🙂
