I have timed “Clean and Build” on 8 of my 30+ projects using version 18. I then installed version 19 and did “Clean and Build” on the same 8 projects. I recorded the performance in the following table
Clean and Build time in seconds Module # number of source files version 18 version 19 1 49 1.71 1.638 2 134 1.359 1.242 3 80 1.431 1.12 4 19 1.386 1.192 5 36 1.224 1.071 6 55 1.163 1.034 7 158 1.768 1.709 8 1 0 0 Totals 532 10.041 9.006 General comments Application opening time seems (subjectively) faster. version 19 1st run of module 1 downloaded some Maven stuff. The figure given is the 2nd run. No changes to the machine or its software or the other applications running between tests. Mac Mini M1 chip, 16GB memory, running MacOS Ventura 13.5.2 (the latest) So it would seem to me that version 19 is about 10% faster when building my collection of Java code. As you can see from the number of files, some projects are trivial (module 8) and some are very complex. I hope that this helps move the discussion forward.

These two reports of that make me reluctant to upgrade, but it is surprising that it is only 2 if this is a general problem. However the thread subject is kind of specific and might be ignored by many users, so...
