The Processor Stack tab
The Processor Stack tab allows you to get full insight in the SXML rendering process.
Smartsite iXperion uses stack-based linear recursion. During the rendering process, Smartsite iXperion keeps track of a large amount of data. Normally, this data is only on the stack, but when a debugger is attached, an instruction tree is built.
The Processor Stack tab is ideal for optimization purposes. As you'll see, aggregated execution times of all SXML assets hit during rendering are displayed. Simply click on tree nodes to drill down to the underlying instructions and find the bottlenecks in the rendering process.
