StreamBase 7.6.0 and ActiveSpaces 2.1.6 listen with timescope current

I am using StreamBase 7.6.0 and AS 2.1.6. I am using the Active Space listen operator. I found that we cant use timeScope as Current. From AS Engineering team we will come to know Current Timescope works faster than ALL. So what is the solution for that in StraemBase? Does ALL work in same way as CURRENT in StreamBase?
