Indeed yes. Running ld-elf.so.1 isn't free. Also, calling PIC libraries isn't free either. Not only that, but even fork(2) is slower when you come *from* a dynamic executable. But for /bin/sh, then ~user etc doesn't work too well when your account exists only somewhere like ldap. Just like /bin/ls -l doesn't show the user and groups. Fortunately the costs associated with this are mostly one-off per exec and are mostly lost in the noise when the commands being run are doing real work. In the days of monsters like mozilla, kde, gnome, gcc-3.x etc, dynamic binary exec times seem to be the least of our worries. :-( Cheers, -Peter -- Peter Wemm - [EMAIL PROTECTED]; [EMAIL PROTECTED]; [EMAIL PROTECTED] "All of this is for nothing if we don't go to the stars" - JMS/B5 To Unsubscribe: send mail to [EMAIL PROTECTED] with "unsubscribe freebsd-current" in the body of the message
