Zend certified PHP/Magento developer

Product create with image takes long time to save Magento2.4.3

When I create a simple product with a single image it takes 17 seconds to save, I have changed the indexing to schedule and removed all extensions and themes.

On debugging further I can see that the delay is caused by the media(media/catalog/product) I have 3000 products where my product image directory size is around 1.5GB. (Directory is mounted on the same server)

On deleting the images on the directory the speed improved from 17 to 4 Sec.

I tried the same on the fresh installation of Magento2.4.3 importing all the 3000+ products it took almost the same time, On dropping the product directory it took only 4sec.

This was not the case on the older version of Magento2.2 the one I had before.

I am stuck for past few days, Kindly help.
