Today I was preparing a new production server farm for SharePoint 2010 when I encountered this fact that there are not many in depth articles/whitepapers on the net that deals explicitly with Excel Services Architecture and How to scale it for different SharePoint topologies.
I have seen that Excel Service Application takes up loads of RAM (physical memory) of the server running Excel Calculation Services.
My current farm server memory layout is
Central Admin - 8GB RAM , Excel Services Stopped
WFE - 8GB RAM , Excel Services Started
DB + WFE - 16GB RAM , Excel Services Started
My question is - How do I verify that when I am opening excel files in the browser inside a site collection , the request is getting load balanced and there is a even distribution of memory allocation after I have started the excel services across both the WFE.
