Hi Ramakrishna! I run Blunders.io. The root issue here is quite simple as far as I can tell - the search profiles are just much larger.
Blunders is not really built for the types of large JFR (Flight Recorder profiling files) uploads that lucene-bench does, and it struggles a bit with them. The main use of Blunders is a real time profiling platform, where many much smaller profiles are used. Lucenebench instead uploads one big .jfr per benchmark run (e.g. https://blunders.io/jfr-demo/searching-2025.10.15.18.03.41/jvm_info). I have not, so far, spent that much time optimizing for this use-case. I will have a look at if I can improve things somewhat - but a workaround that works decently well is just knowing that Blunders has internal caches, and that if you try reloading one of the profiles that timed out it might very well have succeeded later. best regards, Anton On Fri, 17 Oct 2025 at 15:12, Chilaka Ramakrishna <[email protected]> wrote: > Hi all, > > I’m going through profiles on Blunders.io <https://blunders.io>.
