2947	Performance issues with BackendVariable.mergeVariables	Martin Sjölund	Per Östlund	"BackendVariable.mergeVariables has huge performance issues. One way to fix them would be to make the VARIABLES() structure actually a list of VARIABLES() to search. Or to optimize the merging.

There are many ""odd"" calls to convert list<Var> to Variables that are then not used (only merged).

SymbolicJacobian.getSymbolicJacobian costs ~22% of execution time in the 4-bit adder. Most of that is mergeVariables."	defect	closed	high	1.9.4	Backend	trunk	fixed		Per Östlund Martin Sjölund Lennart Ochel Willi Braun
