I have a moderately big flexicontent installation on medatemple gridserver.
We are having performance problems with filesystem access, specially in the image plugin.
The image plugin check for file existence using php function 'file_exists' and in the gridserver this function performs the worst.
I was thinking to eliminate that 'file_exists' check in
Code:
/ Eliminate records that have no original files
$securepath = JPath::clean(COM_FLEXICONTENT_FILEPATH.DS);
$existing_files = array();
foreach($filenames as $filename) {
$filepath = $securepath . $filename;
if (file_exists($filepath)) {
$existing_files[] = $filename;
}
}
and intead run a cronjob to delete from database the records if the image does not exists in the file system, something like:
Code:
DELETE FROM jos_flexicontent_fields_item_relations WHERE field_id = 19 and item_id = <?>;
Where <?> is the id of the item which it image is not found.
So my question is, is this a safe thing to do?
Would I damage my flexicontent installation by doing this?
test by replacing if (file_exists($filepath)) {:
with: if (1) {
to see if there is an effect on performance ?
i say this because the above for original image,
later we do 4 file_exists and 4 getimagesize
Code:
if (file_exists($path)) {
$filesize = getimagesize($path);
...
for the 4 thumbnails of the image fields

medium
large

so it is not only checking if original images, it is also checking if thumbnails exist and are of correct size
so in total you have:
5 file_exists()
and
4 getimagesize()
are you sure it is file_exists() ?
and not getimagesize()
i ask because for getimagesize() we can avoid it by adding a parameter not to check if thumbnails are of correct size,
So are using some profiling tool that gives you timing cost per function ? is the total of file_exists() only from image field or is it from other code too ??
Which PHP profile tool are you using ?
