AFAIR, in this talk http://archive.fosdem.org/2007/schedule/events/ 
profiling_desktop_apps they show how they discovered that Gnome  
applications had a bottleneck in the code that ... loads the Gnome  
icons.  They had a huge list of paths to search and it *considerably*  
increased the application start-up time.  So yes, I wouldn't be  
surprised if doing one PATH search per command would considerably  
slow down `make'.
