Pull Request for Issue # .

Summary of Changes

The System – Language Filter plugin currently calls LanguageHelper::getInstalledLanguages(0) multiple times, each time for one language in the loop. The method itself contains bunch of logic, including file system operator - which in general, slow.

This PR stores the result in a local variable so the method is called only once, reducing unnecessary filesystem work and slightly improving performance.

Testing Instructions

  • Setup a multilingual website with Joomla 6.1
  • Apply patch
  • Access to random pages in frontend of your site with different languages.

Actual result BEFORE applying this Pull Request

Works

Works, with small performance improvement.

I have tested this item ✅ successfully on 0dca53f

I don't see, or expect to see, the performance improvement - but nothing was broken.

Thanks @ceford for testing. It is a slightly improvement, maybe a nano second, not noticeable but it should still be improved :)
