Performance slowdown V4

Hi,

Thank you for this great component, I have been a happy user for many years!

I recently upgraded to V4 and found that my categories with lots of images loads a lot slower. I looked into this and the main issue seems to me the Joomla\CMS\Router\Route::_('...') calls we do to get the Route for the different links (Download/Geo/Exif/..). Which leads to PhocaGalleryCategory::getCategoryById($id), which has 2 db calls in it to retrieve the category information.

For a simple test Category View. with 1 image to display, with download/geo/exif links. This is called 20 times...

Code: Select all

/components/com_phocagallery/views/category/view.html.php(652): Joomla\CMS\Router\Route::_('...')
/components/com_phocagallery/views/category/view.html.php(652): Joomla\CMS\Router\Route::_('...')
/administrator/components/com_phocagallery/libraries/phocagallery/image/imagefront.php(1086): Joomla\CMS\Router\Route::_('...')
/administrator/components/com_phocagallery/libraries/phocagallery/image/imagefront.php(1086): Joomla\CMS\Router\Route::_('...')

/administrator/components/com_phocagallery/libraries/phocagallery/image/imagefront.php(1086): Joomla\CMS\Router\Route::_('...')

/components/com_phocagallery/views/category/tmpl/default_images.php(226): Joomla\CMS\Router\Route::_('...')
/components/com_phocagallery/views/category/tmpl/default_images.php(260): Joomla\CMS\Router\Route::_('...')
/components/com_phocagallery/views/category/tmpl/default_images.php(260): Joomla\CMS\Router\Route::_('...')
/components/com_phocagallery/views/category/tmpl/default_images.php(260): Joomla\CMS\Router\Route::_('...')
/components/com_phocagallery/views/category/tmpl/default_images.php(260): Joomla\CMS\Router\Route::_('...')
/components/com_phocagallery/views/category/tmpl/default_images.php(260): Joomla\CMS\Router\Route::_('...')
/components/com_phocagallery/views/category/tmpl/default_images.php(260): Joomla\CMS\Router\Route::_('...')
Not sure if actually need to do this route call for links that are not directly visible, or that we can maybe do without the db calls in getCategoryById($id)?

Thanks,

Further I noticed that PhocaGalleryCategory::getCategoryById('...') is called another 4 times per image from here: Not s

Not sure if I could prevent that somehow.

Hi, thank you for the info, unfortunately I am not the developer of new router so really hard to say. The only idea which I have is to somehow do singleton for the asking of the ID so the SQL command is not run many times for one ID. I will take a look at it for some next version and for now unfortunately I have really no idea if I will be able to change the new router behaviour :-(
