I am not a developer, just a mere excel power user. I find myself needing to run both of IB's ActiveX and DDE spreadsheets (standard API templates) simultaneously. The former to retrieve real-time margin requirements with the WhatIf function, the latter for Account Information, order entry, etc... Now things become really slow whenever I open 2 different instances of excel to run those 2 spreadsheets simultaneously. I am obliged t do so (I think) as we are not allowed to run multiple TWS sessions for the same account on different PCs. Is there any possibility of sorting this out with hardware? Can one have different CPUs running on a same computer, with an MS Excel session solely tapping into the resources of each CPU? My PC is quite old, but I have already upgraded the RAM to 16GB. Happy to look into any other suitable configuration to sort this out. Thank you.
