    Your command line is a mess, look at the log file:

     

    Command Line: -XX:+UnlockExperimentalVMOptions -XX:+EnableJVMCIProduct -XX:-UnlockExperimentalVMOptions -XX:ThreadPriorityPolicy=1 -Djava.net.useSystemProxies=true -Djava.net.preferIPv4Stack=true -Xmx6g -XX:+UseParallelGC com.strategyquant.strategyquant.SQStarter

     

    Stick to just using:

    -server -Xmx26000m

     

    and replace the 26000 with however many megabytes you want to assign. Should work fine after that adjustment.

    i am not using any CL, i just only start SQX with icon – so this must be some devteam setting, not mine

    with v20.0.0 i have no problem at all, but with the newest one v20.1.1 nothing happens and only the logfile is created in the SQX directory

    i will try also on my server what will happen there, just trying on the second machine

    Thanks Geektrader for this hint! :)

    I changed to the open GraalVM on my VPS with Intel and can confirm the improvements: Faster creating strategies and 50% less RAM consumption! Great! :)

    An error at starting up sqx with the original VM, but this didn’t have an effect on working with sqx it starts well though, vanish after implementing the new Graal VM. But I don’t know if it is related to.

    Great to hear that mein Freund ;-)

    Try the Enterprise Edition as described above, this is even faster.

     

    Auf Wiedersehen :-)

    Hello Traders

    I am using now GraalVM 20.2 (Java 11) Enterprise Edition and I can also confirm, that I see also an appr. +20-25% boost in the number of the hourly generated strategies.
