OK, very very quick benchmark on the realpath stuff System used is an AMD Opteron 142 (1.6ghz) with a gig of pc2100 ram, and Western Digital Raptor sata disk. It's running Debian/unstable, though only in 32bit mode atm. Both tests were run using the standard php5 release rather than current CVS. test.php just runs a passthru() 1000 times on another script which includes 5 files. * before realpath modifications root@mesa:/# time php /home/gaz/test.php real 4m50.380s user 1m23.635s sys 1m22.761s * after realpath modifications root@mesa:/# time php /home/gaz/test.php real 3m12.067s user 1m22.602s sys 1m24.608s Now, imo, shaving over a minute and a half off that original time is bloody impressive. Nice work, Andi.

Just as a bit of a follow-on......

The above was all done on absolutle paths. I've since tried a seperate test with the same number of includes(same files infact) - but this time with the files in php's search path and called them via include "dir/file.php"; much like the typical PEAR usage. This one totally surprised me. root@mesa:/# time php /home/gaz/test.php real 3m12.264s user 1m39.049s sys 1m23.718s Virtually identical. Wow. Ok, I'm seriously impressed with this patch.
