`$subdivision->getLocalName()` is slow (~1s per call), impacts page rendering time

[Crovitche-1623]

Hi 👋

First of all, thank you for this great project and all the work you've put into maintaining it — it's really appreciated!

I'm currently using:

"sokil/php-isocodes": "^4.2",
"sokil/php-isocodes-db-i18n": "^4.0"

I've encountered a performance issue with the getLocalName() method. Each call to getLocalName() takes around 1 second to execute. In my case, I need to display the local names of approximately 10 subdivision on a single page, which results in a 10-second delay just for this step.

I'm using the Symfony Translation driver

Question

Is there a recommended way to optimize the performance of getLocalName() ?

[Crovitche-1623]

I saw that you are not using the cacheDir parameter available in new Translator(...) in the SymfonyTranslationDriver. This might be the cause of the slowness. The MO file are parsed on each call instead of reading the dumped php files.

Indeed, that was that. I made a quick test by specifying the cacheDir and It's now very fast. I'll try to make a PR ASAP.
