Hi Anton, Thanks a lot for the quick follow-up and for improving the caching behavior!
I just rechecked the same profile <https://blunders.io/jfr-demo/searching-2025.10.15.18.03.41/jvm_info>, it’s definitely loading much faster now (and loads on the first try), and the visualizations are showing up consistently. Thank you for the fix! Best, Ramakrishna.
