Title: Benchmarking getting formulas in bulk vs one-by-one
Post by: Visisthebest on December 29, 2020, 06:16:08 AM
Old blog post benchmarking VSTO and Exes getting formulas in bulk or one-by-one:
https://surrogate-tm.github.io/wmorein/2007/11/13/solution-performance-tip-1-getformulas-and-setformulas.htm

Amazed how slow out-of-process executables are 😱

Also noticeable how Visio’s many-shapes slowdown becomes a much bigger issue with 1000 versus 100 shapes, as using GetFormulas (bulk) still delivers much better performance with VSTO 1000 shapes, but not as spectacular a difference as with 100 shapes.

PC from 2007 or earlier, so I wonder how much better is the performance is on a cheap AMD Ryzen 4000 notebook today (or a more expensive Tiger Lake notebook), although I understand older Visio versions may have done things much faster. Why did newer version of Visio slow down so much?

Personally I think Visio 2019 is fine below 1000 shapes, although rendering shapes with gradients in a 500+ diagram could also be faster.

I saw a Microsoft presentation about Visio 2019 where they said they improved diagram rendering performance compared to Visio 2016, I think it was at Ignite when they presented 2019.
