BW performance issues

Hi gurus,

today i import a my developpemnts on the production system and everything is Ok exept time of update. when i load data into PSA there's no problem but in the infocube update step it is too long.

But on my dev or itegratin system for the same infocube and sema volume of data i didn't have any such problem

I don't know where i have to check.

ST22 --> nothing

SM21 --> Nothing

Thanks

Cyril
