Hi there! Please grab the benchmark workbook from one of the two links below:
XL 2010: http://ppvt.pro/2010perftest
XL 2013: http://ppvt.pro/2013perftest
Then grab a stopwatch and record the times for the two specified slicer clicks in the workbook - the Test 1 and Test 2 slicer buttons.
Fill in your results in this quick survey, and we'll share the overall conclusions on PowerPivotPro.com
Thanks!
