CPU and Memory consumption Very High

I have installed the brand new RC5 but cannot run it because its CPU and memory load is excessive. This is third time and leaving it to run for more than 15 before attempting to build any strategies. So now its frozen CPU revs up and down, and refuses to do any work!

Tried to run basic build strategy - everything default.

At my computer it works fine. I give the SQ 32 GB Ram and all is ok.

I have installed in a different folder - not the older containing RC4. Runs better but CPU still unsustainable.

what kind of computer do you have?


YOu can change the performance settings and let it use less cores.


It would be also helpful if you can attach your Builder config here.

The image capture below is an update of what is happening.

This was not happening in previous releases. There were crashing problems, nut have not had any crashes with this release.

As said before, I have not changed anything that would explain the memory & cpu behaviour.

Has struggled to generate 5000 strats as shown and reached it max memory allocation.

because of program crashes we modified the way orders are stored. Before they were stored to offheap memory, it was the reason for crashes. Now they are stored to Java heap memory.


Can you please attach also your build setting here? I need to know what kind of strategies you are trying to generate.

Strategies should have their memory freed when they are stored into databank and not used for some time.

Hi Mark, sorry was unable to respond sooner. The problem is that I cannot access the configure. I have tried to save the conf as new template but no luck. I have to access the template or even overwrite it, but cannot. This is the error I am getting.

Just to add: The conf I am using is the original basic except I have increased that databank strategy limit 5000. Nothing else changed

this last error "Exception: Parameter 'projectName' is missing" - when exactly did it happen?


I see you have open menu on the top right, but you said that you cannot save project configuration, which is in the menu next to Settings.

ok, and does it still work like this? 


Are you are still unable to save config in Builder, Retester and Optimizer?

Yes, cannot save builder. I have not bothered moving on to re-tester because of the issues currently.

it is hard to say what exactly to do to fix this problem. In RC6 we made better handling of strategies in databank, they shouldn't be CPU intensive.


It seems you also have problem with File dialog - some people experience issue with it as well, there is a possibility to switch to basic file dialog in Global program settings.


Other than that, program should be running fine. Please check the new RC6 and report any problems.
