<div dir="ltr"><div>Hi Gerd,</div>What about if you compile mkgmap with java 9 or higher - and run it on Java 8 - this also applies or not? Or asked differently - is this dependant on the compilation system or on the executing system?<div><br></div><div><br></div><div>Felix</div></div><div class="gmail_extra"><br><div class="gmail_quote">On 16 May 2018 at 15:53, Gerd Petermann <span dir="ltr"><<a href="mailto:GPetermann_muenchen@hotmail.com" target="_blank">GPetermann_muenchen@hotmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi all,<br>
<br>
it seems that the new Garbage Collector (G1GC) that was introduced with Java JRE 9 causes longer run times for splitter and mkgmap.<br>
I've played with some options and found that the use of -XX:+AggressiveHeap seems to be a good idea when you use these newer JREs.<br>
<br>
Without this option the java programs tend to allocate more memory and thus the OS might start to swap.<br>
