High-performance caching is very important to me. When you cache the images, such as for the most visited products and pages, it is faster to retrieve them because they are already in-memory. This means they load faster compared to accessing other products that are pulled from storage, which can take longer.
I do see an impact from lazy loading. With lazy loading, as a user accesses the product page, images load in an asynchronous way, meaning not all images load at once. For example, if there are ten products, they do not all load together, which saves bandwidth instead of loading all thousands of products at once.
For analytics, I rarely pay that much attention to them, though they are useful for monitoring the website. I have not experienced a challenge where I really need to go deep into the analytics; they are quite optimized primarily for bandwidth monitoring.
I have not experienced any technical disadvantages with ImageKit, though I have not tried their video storage and delivery aspect.
I would rate this review a 9 out of 10.
