Astronomical Calculations tool extremelly slow

[EnMazinger]

Dear all, I searched the forums and I did not found my issue. I have a desktop computer with Intel(R) Core(TM) i7-6700 CPU @ 3.40GHz with 12GBRAM memory, running Stellarium 0.22.0. The performance of the program is good when accelerating time speed. I can see animation of the sky quite smoothly even with increased time steps like months or years. I get around 6.5FPS speed. Zooming in/out and finding objects is also ok. The issue comes when I select the window for astronomical calculations. In this window everything goes really slowly. Updates take time, short period ephemerides calculation takes long time. It is like I was using a completely separate calculation engine, and this engine is broken. I own another laptop computer with slower Intel i5 processor. In this computer everything goes quick and smooth as one could expect. The issue on my i7 computer has been around in previous versions of Stellarium with no sign of improvement as newer versions are being installed. Anyone has an idea on how to fix it? Thank for your time and support.

Having a very large number of objects in 'C:\Users\Jordi\AppData\Roaming\Stellarium/data/ssystem_minor.ini' can slow down the program. I would like to suggest trying to delete this file (rename or create a backup of the file before deleting it) and start the program again. Add only objects that you really want should help.

[EnMazinger]

Wooow !! Very impressive right now. My ssystem_minor.ini file was 17MB big. I renamed it as system_minor.ino just to make sure the program does not find it. Now the astronomical calculations work really fast again. Thank you for the help! From now on, I will check that this file does not get big.

[alex-w]

This is important questions: please describe how you used AstroCalc/Ephemeris tool, for which objects?

[EnMazinger]

Nothing special in particular, sometimes I want to track the minor body track on the sky along the days. Sometime I want to sort by filter a given set of objects like Caldwell. Sometimes I want to find phenomena between asteroid and planets in a given time period. Stellarium is such a magnificent piece of software !

[gzotti]

There is nothing we can do about it apart from finding a way to push the asteroid computations into GPGPU programs or other ways of parallelization. For now I close this.
