Hi Gerd
i'm not sure what you are looking for. In my build environment i'm using
java 1.8.0_241 (64 bit) and as my laptop have 32 Gb of memory availiable
my command line to build is like this :
java -Xmx30000m -XX:-UseGCOverheadLimit -ea -jar
-Dlog.config=logging.properties "c:\Program Files
(x86)\KartenTools\mkgmap\mkgmap.jar" ....
and depending on which map i want to build, the occupied memory runs up
nearly to 30Gb

Hi Gerd
I don't have a 64bit environment or that much memory. In my normal
environment, I get:
$ java -Xms1500M -Xmx1540M -jar ../mkgmap.trunk/mkgmap.jar \
dummy.osm dummy.osm dummy.osm
Time started: Wed Feb 05 12:56:28 GMT 2020
Setting max-jobs to 4
Number of MapFailedExceptions: 0
Number of ExitExceptions: 0
Time finished: Wed Feb 05 12:56:29 GMT 2020
Total time taken: 1 second
-Xmx1540M is the maximum value that allows Java to start up on my
machine.
With a newer version I loaded in October, but it didn't have any
obvious advantages:
$ /opt/jre1.8.0_231/bin/java -Xms1500M -Xmx1540M \
-jar ../mkgmap.trunk/mkgmap.jar \
dummy.osm dummy.osm dummy.osm

please try this command with openjdk 11 or 13 64Bit:
java -Xms4G -Xmx10G -jar mkgmap.jar f:\osm\dummy.osm f:\osm\dummy.osm
f:\osm\dummy.osm
This is what I get:

To reduce the run time, consider increasing the amnount of memory
available for use by mkgmap by using the Java -Xmx flag to set the
memory to more than 41000 MB, providing this is less than the amount
of physical memory installed.
