@debe thank you for taking a look! First off, mockito is troublesome. we can take it out completely if there is a way to setup solr without it. I added it only for the transient cores part. same for the lookup misses, it was just an attempt to reproduce the results. > I think you actually need to do something while holding the lock like it is in reality. I don't completely follow there. what else happens inside the lock block from getCoreFromAnyList? ideally we would test the code as is, I don't see anything else inside that method. by introducing the consumer you are artificially increasing the time spent inside the lock, is this a better mirror of a running system? > I think one should limit the number of threads to the number of CPU cores, otherwise you're benchmarking context switching of OS threads. I agree with this point, anything we can tweak on the benchmark settings to get it closer to real life is good for me. > To get an overview which public methods from SolrCores and CoreContainer are actually called and how frequent, I've checked a recent flight recorder image from one of our production machines. thank you for this data. I would like to use it as a reference for the benchmark, but ideally we would setup the core without any interventions (still not 100% sold on the extra consumer you added). -- This is an automated message from the Apache Git Service.
