Re: Bug #14248: uniqid() is extremely slow (20ms per call)

I looked at php_combined_lcg() and saw that it uses LCG, it looks like a macro but I've found anywhere else in the source. I looked at the source to view how session_id is generated (using seconds, microseconds, and php_combined_lcg -> standard/lcg.c) Thanks in advance Andrey Hristov ----- Original Message ----- From: "Derick Rethans" <d.rethans@jdimedia.nl> To: "Teodor Cimpoesu" <teo@gecadsoftware.com> Cc: <php-dev@lists.php.net>; <bartvb@iae.nl> Sent: Tuesday, November 27, 2001 11:54 AM Subject: Re: [PHP-DEV] Bug #14248: uniqid() is extremely slow (20ms per call) > On Tue, 27 Nov 2001, Teodor Cimpoesu wrote: > > > I guess it gets entropy from /dev/[u]random, but when it is exhausted it > > cannot do much but to wait for more entropy. > > Wrong guess, it does not.
