libtool performance status

[Bob Friesenhahn]

Since libtool performance has become a concern, I have been measuring 
build times for a reference project in order to evaluate progress.  I 
selected a project at random and ended up with one called 
'GraphicsMagick'.  I am testing the build on a FreeBSD 7.0 system with 
two 2.4GHz Intel Xeon CPUs.

I am saddened to report that as of yesterday, build times for git 
libtool are now similar to libtool 2.2.2.  This is not to say that 
there has not been progress.  The reported system times have gone down 
(from 113 to 104) but the overall build times have crept back up so 
that they are similar to before.  This means that users end up waiting 
just as long for the build to complete.

I have attached the raw data, which includes some timings that I did 
with FreeBSD's /bin/sh and ksh93.
