[SCIP] Inquiry Regarding SCIP Solver Performance with Parallel Option

[xu liwei]

Hi,
I have been testing various MILP models with the SCIP solver and noticed that enabling the parallel option (using "parallel/maxnthreads" 4) results in slower performance on my 8-core CPU, which seems counterintuitive. In most cases, the parallel execution mode appears to decrease the computation speed rather than improve it.
I am currently using the pre-compiled version of SCIP on a Windows platform and would appreciate any guidance or suggestions you might have regarding this issue. Could it be related to a misconfiguration, or are there other factors that might explain this behavior?
Thank you very much for your time and assistance. I look forward to your insights.
Best regards,
Leslie
