This was executed on Linux.
So, I see a performance increase with Tcl/Tk 9.0.0 instead of a decrease.
B.t.w.:
- Having replaced in your script [package version Tk] with $tk_patchLevel
to prevent that multiple installed Tk versions are reported.
- The combination Tcl8.7 and Tk9 is not avaiable to me
- Did you perhaps use different compiler optimizations for your builds?
(My builds are all without compiler optimizations.)
