I just wanted to share my “new” find. As always, I am exploring options about how to increase the speed of SQX for my daily workflow by tuning parameters, garbage collectors, etc. Lately, I´ve learned about GraalVM, which is a relatively new JIT-compiler that has maximum performance as its goal and has been shown sometimes to be up to 30x faster than if executing code in the standard JRE / OpenJDK runtimes that SQX is using right now. Over here is an excellent video about how it works, why it has been made and with some performance tests: https://www.youtube.com/watch?v=GinNxS3OSi0 For example: Twitter is running all their Java stuff on GraalVM instead of JRE / OpenJDK for a while now and have noticed a considerable drop in CPU and RAM usage.
And now the great part: using it with SQX is as easy as downloading the latest Windows binary from here https://github.com/graalvm/graalvm-ce-builds/releases
Simply unpack the ZIP file into the J64 of SQX (previously delete or rename the folder) and just continue working with SQX as you always did. Personally here is what I have experienced since replacing it and of course, using the same settings in SQX as before:
– about a 15% performance increase in strategy generation speed
– approximately a 40% drop in memory consumption (which is AMAZING given that I can now work with less RAM)
– no errors or crashes of SQX just works the same as with JRE / OpenJDK
As this is open-source, I would highly recommend that SQX is being shipped with GraalVM in its default configuration, as this seems to be amazing! There also is an Enterprise Edition available that seems to be even faster, but it´s 193 Euro/year and I haven´t tested it yet.
Have fun crunching strategies ;-)
You are most welcome. I am in 48 hours now and it keeps going at +15% performance and half to the RAM it used before for the same task. What an amazing JVM!
The best thing is, that you can download and use the enterprise version by using the “TRY FROM OTN” button at https://www.oracle.com/technetwork/graalvm/downloads/index.html and quickly registering with Oracle. And indeed, that version is even faster (+20% performance for me) as promised by them.
good finding – testing and its seems that the graal EE version is faster

Yes, the Enterprise Edition is clearly a good bit faster than the open-source one (which is already much faster than the typical JRE / OpenJDK stuff). Once again, you can grab the Enterprise Edition for free here:
Have fun :-)
