Some of the figures do not seem to match the numbers (is browser cache invalidation possible?)

See for instance https://rebench.dev/TruffleSOM/compare/182199257927581758dfef9a1bd69de166205207..c1e729af0bbca3442421659806e45d0490c06150

Filter on the IfNil benchmark and the images for micro-startup/TruffleSOM-native-interp-bc don't show the -72% difference but perhaps -5%.

Ok, so, I did have regenerated the report before, and this might be a caching issue.
After hard refresh the specific svg file https://rebench.dev/static/reports/TruffleSOM-182199-c1e729/inline-512.svg it looks more correct.
So, should investigate what the options are to make sure the browser reloads after regeneration. Though, I think I serve the svg directly via the http server...
