I reported something like this towards the end of last year. Have not found any cause at the moment but exists in 9.0.0 and 9.1.0. Originally though it was query based but I see the issue when requesting localhost:18983/solr/img/solr.svg<http://localhost:18983/solr/img/solr.svg>
For me this was occurring under Windows server 2008 and 2019 (OpenJDK 11 and 17 tested).

I am able to reproduce the behavior as follows pretty easily: docker run -p 8983:8983 -d solr time curl http://localhost:8983/solr curl http://localhost:8983/solr 0,00s user 0,01s system 0% cpu 8,018 total As you can see, the request takes about 8 seconds. I also tested with version 9.0.0 and the issue is present there as well. However if I switch to version 8 of Solr, the request takes only 39ms. docker run -p 8983:8983 -d solr:8 time curl http://localhost:8983/solr curl http://localhost:8983/solr 0,01s user 0,00s system 14% cpu 0,039 total I am running the following system: Operating System: Manjaro Linux Kernel: Linux 5.15.89-1-MANJARO Architecture: x86-64 Hardware Vendor: Dell Inc. Hardware Model: XPS 15 9520 Firmware Version: 1.2.0 I checked the logs and there seem to be no ERRORs reported. In case I missed smth, I attached the logs. Apart from the slow response time, Solr seems to be working okay. I will happilly provide any additional information you might need. Thank you!
