I don't think that's the issue, so much as that FreeBSD *doesn't  
support* UTF-8 collation so the database has to use its own (possibly  
slower than platform-optimized) collation libraries.

(en_US.UTF-8/LC_COLLATE is symlinked to a US-ASCII collation sequence  
which is identical to binary.  This is incorrect for UTF-8; there're  
all kinds of strange things that need to be done to sort UTF-8  
properly.)
