Applying the patch improves performance (on my Threadripper 2950X)from: JFX 21.0.2+5 average run time: 2460 to: JFX 23-internal+0-2024-02-01-061822 average run time: 1119 so the speedup is quite remarkable and will probably be even better, if I follow @Maran23 advise to also pull `cell.updateTableRow(tableRow);` out of the loop. I will hopefully be able to provide an improved PR tomorrow. > A side comment: the default implementation of resizeColumnToFitContent() is > to iterate over all the rows, and I think this is not right.

However, in order to "not break things" we would have to introduce an API to users to be able to control the number of rows they want to be taken into account. Definitely a separate improvement. ------------- PR Comment: https://git.openjdk.org/jfx/pull/1358#issuecomment-1926559011
