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.

i reconfirm a 30% improvement in memory usage (less memory) on one of the most generated and profitable pair, XAUUSD, in working with 10.000 strategies in databank. This setting is one of the most demanding possible.

in the past, with 64GB, i had over 100% and occasional freezing, now with the latest graal versions, i have 45GB occupied out of 64GB when the databank is full

its a notable and very important upgrade, however, although its not critical, still 64GB memory is the minimum…32GB is not enough but given the memory prices, i doubt the price would be an inconvenient

after some 24 hours of installing a new graal version, i got a “makop” virus which encrypted everything

recovering is almost impossible so i will do a fresh install

i recommend great care in installing java related files, this is one of main sources of infection and the fastest easiest way is a fresh install

where did you get the 20.3 – from oracle website or somewhere else?

No such virus here and I highly doubt that it is related to that. Oracle is clearly not distributing viruses in their VM´s, nor have I ever seen any other Java distribution containing a virus in the last 20 years.

i got it from http://www.graalvm.org

i also had some doubts that it came from there but the coincidence is striking, i didnt had any problems in many years of intense personal torrent activity, movies, games….etc

i implemented several changes including securing the connection, installing a better antivirus and internet security and pay more attention

i cleaned the system but i have to run a repair on windows and reinstall everything else

the good news is the desktop is for SQ only so i had a barebone system with only the OS, minimal drivers and the SQ, nothing else. I didnt had any files or EAs stored. I formatted the partitions because the encrypted files are impossible to recover

Keeping daily full drive backups might be a good idea for you, saved my life a few times over the last years. You just switch back to 24 hours ago with that in about 20 minutes. Did not have to reinstall Windows for at least 10 years now thanks to that. http://www.drivesnapshot.de/en/index.htm is your friend for that and it´s portable and just 500kb in size, a single EXE file. No ugly bloated installs for disk imaging software.

That being said, 20.3 is running here for days, with no virus or anything suspicious.
