I've been doing some tests and have found that this code runs about 2.5 times slower under 4.3.2 than it did on 4.1.2 on the same machine (running OS X):
<?php $filename = 'file.html'; $fd = fopen($filename, 'rb'); $content = fread($fd, filesize($filename)); fclose($fd); echo $content; ?>
I did some tests with fs_usage to check file system calls and found that for a zero length test.php file, 4.3.2 makes the following additional calls beyond 4.1.2:
1 chdir /Library/WebServer/Documents/rot/bench 1 fchdir 12 fstat 5 fstatfs 5 getdirentries 7 lseek O=0x00000000 1 lstat test.php 6 lstat (., .., ../.., etc. 6 open (., .., ../.., etc) 1 stat
The fread example above made the following additional calls in 4.3.2 beyond 4.1.2:
2 chdir /Library/WebServer/Documents/rot/bench 2 fchdir 32 fstat 15 fstatfs 15 getdirentries 16 lseek O=0x00000000 1 lstat file.html 1 lstat test.php 18 lstat (., .., ../.., etc.) 17 open (., .., ../.., etc) 4 stat 1 stat .
some of my counts my be slightly off - I counted them by hand.
