--- Comment #3 from Cody Lerum <[email protected]> --- I ran into this same issue today when making the move from Java 8 to Java 11 and from POI 3.17 to 4.1.0 and I've narrowed this down to a slowdown with Java 11. It doesn't matter if you are running 3.17 or 4.1.0 When running the simple reproducer (taken from the SSPerformanceTest) below with POI 4.1.0 Elapsed 2.71 seconds for arguments [HSSF, 5000, 15, 1] on Java 1.8.0_212 Elapsed 35.08 seconds for arguments [HSSF, 5000, 15, 1] on Java 11.0.4 Elapsed 33.27 seconds for arguments [HSSF, 5000, 15, 1] on Java 12.0.1 The situation seems resolved in Java 13 Elapsed 3.44 seconds for arguments [HSSF, 5000, 15, 1] on Java 13 FYI this This is still an issue on the latest nightly pulled from AdoptOpenJDK: Elapsed 37.13 seconds for arguments [HSSF, 5000, 15, 1] on Java 11.0.5 Commenting out the sheet.autoSizeColumn(i) yields: Elapsed 0.54 seconds for arguments [HSSF, 5000, 15, 1] on Java 11.0.5 https://gist.github.com/codylerum/5e302c4cd69e133206ddde9e50f44daa -- You are receiving this mail because: You are the assignee for the bug. --------------------------------------------------------------------- To unsubscribe, e-mail: [email protected] For additional commands, e-mail: [email protected]
