Description

Huge (3+x!) performance degradation with "fl=abc_*" occurs with version 9.5.0 due to the use of

org.apache.solr.common.util.GlobPatternUtil.matches

instead of (in <=9.4.1)

org.apache.commons.io.FilenameUtils.wildcardMatch

, which is very inefficient and was introduced with Github pull request | issue SOLR-17022

Call tree 9.4.1 vs 9.5.0 attached
