I am not seeing quite the difference between libtool releases that you
are although I see a big slowdown starting with 2.4.3. These timings
are for optimized builds of GraphicsMagick on a 12-core GNU/Linux
system using -j 12:
2.4.2 : 23.613
2.4.3 : 31.697
2.4.4 : 28.236
2.4.5 : 28.514
And here are timings for a non-optimize (-O0) compile with no debug
symbols:
2.4.2 : 8.629
2.4.3 : 13.216
2.4.4 : 13.012
2.4.5 : 13.281
I see similar slowdowns on an Illumos-based system, so it is not
specific to GNU/Linux.
It is curious that there is more impact for the optimized builds.
