iFix 5.8 ETR trends take a long time to populate

Hello all.

I recently built a 24 hour trend screen with 4 individual charts for operations. When you first navigate to the page, it can take upwards of 5 minutes before the trends populate. Once populated they work fine. I am curious if it is because of how many data points I have?

Each trend is using an ETR block with an Average Compression of 15, and the AI block has a Scan Time of 10. My chart has 600 data points.

According to my math;
(10 sec scan time ) * (15 sec compression) * (600 points) / 3600 seconds = 25 hours of data, with each point being 2.5 minutes apart.

Any suggestions?

Thank you in advance.
