Bloated syscall times wind up being a death by a thousand cuts when your workload is syscall heavy.
One simple, common, example is plain old autotools configure scripts. I have no love for autotools generated configure scripts (and in fact hate them with a passion), but I've long observed they crawl on MacOSX and go much faster on Linux. They do lots of syscalls (tons of fork/exec/open/close/stat).
