Performance Advisor report creation is slow

Hello folks,

We're using the headless function of Streamline to create Performance Advisor reports.

We're doing Streamline captures with a duration of up to 4 minutes. This results in .apc files ranging from 1.4GB to 1.9GB depending on the captured device.

Creating reports (json + html) from these captures feels rather slow (5-10min fetching data and another 10min+ to generate the reports).

The created reports are quite tiny (~4KB for json and ~2MB for html).

Is this expected behavior or this there something we could do to improve those timings?
