We have ~170000 dynamic fields like abc_xxx, and requests like /select?fl=abc_* took ~180ms with 9.4.1, but after upgrading to 9.5.0 such requests now take ~620ms to execute.
It seems in 9.5.0 org.apache.solr.common.util.GlobPatternUtil.matches used instead of org.apache.commons.io.FilenameUtils.wildcardMatch Which leads to huge losses in performance. Here is the call tree from the profiler: 9.4.1 https://i.imgur.com/2gubfDr.png 9.5.0 https://i.imgur.com/JIZ1E9u.png
