-- I am using the following command line: 
java -enableassertions -jar -Xmx7200M mkgmap.jar --max-jobs=3 --style-file=new5 %generate-sea% --reduce-point-density=5.4 --reduce-point-density-polygon=4 --suppress-dead-end-nodes --index --delete-tags-file=deletetags --blacklist-tags-file=deletetags --adjust-turn-headings --ignore-maxspeeds --ignore-turn-restrictions --remove-short-arcs=4 --location-autofill=1 --description=velomap_%abr%_%date% --route --country-abbr=%abr% --country-name=%country% --mapname=%mapid%0000 --family-id=%mapid% --product-id=1 --series-name=velomap_%abr%_%date% --family-name=mtbmap_%abr%_%date% --tdbfile --overview-mapname=mapset --area-name=%country% %path%\%mapid%00%tile%.osm.gz

You will need at least 6 GB of Ram to use --max-jobs=2 on countries like Germany. If you use --max-jobs=1 then 4GB should be sufficient. Please note, compiling your own maps is not easy and I cannot help you here. Please don't ask me why I did something this or another way. Only contact me if you find bugs (and have tested that they do not create other bugs).
