            Bug ID: 57884
           Summary: XSSFDataFormat.getFormat is slow with large numbers of
                    formats
           Product: POI
           Version: 3.12-dev
          Hardware: PC
                OS: Linux
            Status: NEW
          Severity: normal
          Priority: P2
         Component: XSSF
          Assignee: dev@poi.apache.org
          Reporter: apache@gagravarr.org

As discovered when working on #57880, for XSSF, creating 33,000 cell styles is
30 times faster than creating the same number of format indexes. For 5,000 cell
styles and formats, creating the cell styles is only 3 times faster than
creating the formats.
