\$use\_sub\_dirs {#variable.use.sub.dirs}
|
||
|
|
================
|
||
|
|
|
||
|
|
Smarty will create subdirectories under the [compiled
|
||
|
|
templates](#variable.compile.dir) and [cache](#variable.cache.dir)
|
||
|
|
directories if `$use_sub_dirs` is set to TRUE, default is FALSE. In an
|
||
|
|
environment where there are potentially tens of thousands of files
|
||
|
|
created, this may help the filesystem speed. On the other hand, some
|
||
|
|
environments do not allow PHP processes to create directories, so this
|
||
|
|
must be disabled which is the default.
|
||
|
|
|
||
|
|
Sub directories are more efficient, so use them if you can.
|
||
|
|
Theoretically you get much better performance on a filesystem with 10
|
||
|
|
directories each having 100 files, than with 1 directory having 1000
|
||
|
|
files. This was certainly the case with Solaris 7 (UFS)\... with newer
|
||
|
|
filesystems such as ext3 and especially reiserfs, the difference is
|
||
|
|
almost nothing.
