4552	EvaluateParameters scales as O(N^2) with large parameter arrays	Francesco Casella	Patrick Täuber	"Thanks to Thomas Beutlich, we have recently added a new set of tests to the ScalableTestSuite which use large data arrays for table-based signal generation.

The performance of {{{evaluateParameters}}} in the set of tests {{{ScalableTestSuite.Elementary.Tables.ScaledExperiments.TimeTable_N_XXX}}} is the following:

||=N=||=Time=||
||2000|| 1.36||
||4000|| 5.52||
||8000||21.73||

which clearly scales as O(N^2^). BTW, I don't see any {{{Evaluate=true}}} annotation on the data tables, so I'm not sure why and where all this time is spent evaluating parameters.

Apparently, this doesn't happen with {{{ScalableTestSuite.Elementary.Tables.ScaledExperiments.CombiTimeTable_N_XXX}}}. I'm not sure why, since both share the same large scale {{{table}}} array."	defect	closed	high	1.13.0	Backend		fixed
