Decreased performance IDEA Statica worker

Hi Support,

Recently we are experiencing a strong decrease in the performance of one of our applications that is using IDEA. The decrease in performance started with using a new IDEA version (IDEA Statica 22) in combination with a new worker(v5.3.1). Calculations are send to the worker and take a very long time to return result files (up to three minutes, that used to be 20 seconds).

The following log from my development environment gives an example:

Have you heard this before? Is there anything I can do to increase performance again?

Hi Bart,

Before you switched to IDEA v22 I assume you were using v21?

Hi Kevin,

I am not sure about that. Before we were using a direct worker to IDEA RCS (version 10), we switched to IDEA Statica v22 (that can acces IDEA RCS) a while ago. Since then the performance dropped a lot

Do you also return the .ideRcs. file using the return_rcs_file=True argument in IdeaRcsAnalysis?

Could you DM me the input XML file so we can check whether the viktor-idea integration is slow, or the idea calculation itself.

This is fixed with the latest worker (v5.4.0) which can be downloaded here: Workers | VIKTOR Documentation
