First of all I would like to to thank Geek for his research under performance 🙂
I have downloaded the Zulu Java, made same as in first post. What I see is no better performance. I have used Geek’s command line before install Zulu.
After installing ZULU and start random generation in 95% cases I get :Generated new Strategy 0.186 – dismissed, reason: Invalid exit rules ….. 0.202 s.Generated new Strategy 0.187 – dismissed, reason: Invalid exit rules ….. 0.218 s.Generated new Strategy 0.188 – dismissed, reason: Invalid exit rules ….. 0.258 s.As far as I remember, when I was generating strategies, the reason for dismiss was too low NET or too big DD etc. Now most of them are dismissed by “invalid exit rules”.What’s more, after back to “old” Java, I get same font as it was on Zulu , and still the same reason for dismiss.Anyone also have same problems?
thanks for creating such a good thread…
i have applied the command line option as well as now trying with Zulu. I am running for 10M TF (Russel) but strategy run time is pretty much same before and after (2 strategy per second avg). However memory usage overall went down from before.
May be because i am using 10M data. I will play around with different time and will post my findings. i have tools-options- set to 2 threads.
I have low configuration in my PC now – AMD A10 5700 3.4 Gz dual core 12 GB
i am running 2 instances on it. My CPU utilization at present upto 90 to 95% with 8.75GB.
I’m trying both the command line and Zulu and these changes do make a big difference! Now generating strategies is much faster than before and memory usage is well managed 😀
Thank you very much for the great tips, you rock!
