Using strace I found what appears to me a strange behavior The strange behavior I want point out is related to a sequence of tentative httpd/mod_php5 does in order to read an php page. In this particular case apache httpd servers tries 8 times before reach and read the file (if you want I can send the complete strace output) More strange all these tentative seems to be correctly completed because of success (0) return code for each line. Ffor every file should be served by apache httpd, apache httpd tries to lstat all directory in path more times: lstat("/usr", {st_mode=S_IFDIR|0755, st_size=4096, ...}) = 0 lstat("/usr/local",

https://externals.io/message/48840#48843 · In reply to: #48842 Hi. Shouldn't we seeing failed lstats if the include_path would be the problem? And I thought that the php engine itself tries to cache the fileinfo, to minimize the lstat calls ( see http://hu.php.net/manual/en/function.clearstatcache.php ) So I think that we shouldn't see this much duplicate lstat calls.

to a misconfiguration of php? This doesn't look like a PHP misconfiguration. It looks more like an application-level issue. Do a grep for "realpath" in your application code. A single call to `realpath()` would cause that tree of stat calls you see. Also, you might be overflowing your realpath cache. PHP 5.2 is not using the cache very efficiently. This is fixed in 5.3. But try increasing your cache ttl and the size as well. eg. realpath_cache_size = 256k realpath_cache_ttl = 7200 -Rasmus --- ## #48853 — Michael Shadle — 2010-06-20T19:51:30+00:00 URL: https://externals.io/message/48840#48853 · In reply to: #48850 Is this only useful for 5.2.x and is it only for `realpath()` or is it for any sort of path lookup and caching?

It is more likely a cache problem. Fix your realpath_cache settings like I suggested. -Rasmus --- ## #48937 — Stas Malyshev — 2010-06-21T19:39:38+00:00 URL: https://externals.io/message/48840#48937 · In reply to: #48927 Hi! > could anybody tell me why also for every single php file engine must lstat > all path? > Why php engine don't simply try to open directly the file? There are some places where PHP engine has to know "true" name of the file - i.e. filename that would be the same for each file regardless of how it is accessed - through relative path, symlinks, etc. Example can be {include|require}_once. For that, it needs to figure out the whole path. It is done only once per file, then cached. If you seeing it on repeated runs in the same process, increase your realpath cache size (yes, the default is way too small for any big app). -- Stanislav Malyshev, Software Architect SugarCRM: http://www.sugarcrm.com/ (408)454-6900 ext. 227 --- ## #48950 — Vincenzo D'Amore — 2010-06-23T11:39:24+00:00 URL: https://externals.io/message/48840#48950 · In reply to: #48937 Many thanks to everybody helped me.
