Sage FR strangely slow invoking Excel

Have an RDS situation where FR interactively is very slow starting Excel but fast as usual executing FR report

But if you record a macro and run the macro it is fast by a factor of 5 to 10

literally macro runs in 8 seconds and Sage screen runs in 90+ seconds

A brand new profile on RDS works fast

Any suggestions as to why (beyond possible Profile corruptions) ? 

Thanks
