JVMOptions -Xss?

[mcourtot]

Looking at the info.plist file content, it reads:

JVMVersion

    <string>1.8+</string>
    <key>JVMOptions</key>
    <array>
        <string>-Dapple.laf.useScreenMenuBar=true</string>
        <string>-Xss16M</string>
        <string>-Xdock:name=Protégé</string>
        <string>-DentityExpansionLimit=100000000</string>
        <string>-Dlogback.configurationFile=conf/logback.xml</string>
        <string>-Dfile.encoding=UTF-8</string>
        <string>-XX:CompileCommand=exclude,javax/swing/text/GlyphView,getBreakSpot</string>
    </array>

I couldn't figure out what the Xss options is - help? I checked https://developer.apple.com/library/mac/documentation/Java/Reference/Java_VMOptionsRef/Articles/JavaVirtualMachineOptions.html#//apple_ref/doc/uid/TP40008049

I was trying to increase the memory options as usual and just added

-Xmx12000M

         <string>-Xms2000M</string>

which seem to be working fine.

The Xss option specifies the stack size. We increased this from the default to support reasoning with some particular biomedical ontologies.

I'll leave this issue open as a reminder to add some documentation about this.

I was getting lousy performance out of P5 with GO loaded until I deleted the -Xss setting. Before deleting (& with -Xmx set to 6G) the performance with sluggish, with the cpu frequently maxing out rendering the editor unresponsive for up to a minute at a time. Now seems fine.

Closing this because it seems stale.
