When uploading images if you have more images uploaded directly from phone with over 1,5-2MB it takes a lot of time to generate all the thumbnails, sometimes over 10 seconds and this might lead to users cancelling and not adding the new listing. You should implement something new to generate thumbnails in background or when a user first visits the listing. This also applies to Ad Importer plugin, it takes a huge time to add 10 or more listings with import.

If I would be user, I would rather wait for 10sec so I can review my listing, then waiting few minutes for cron to pick it up.
Pretty sure that fancy loading message with what is going on would be more helpful.
For ad importer plugin, try to optimize images and do not send larger images then needed.

What I found on google is that faster CPU make imagemagick faster as well.

You are probably right but you guys need to find a solution for this because I have other websites and I upload 10-20 images, even bigger in size, they make a lot more thumbnails and still load faster on exactly the same hosting.

Then pay developer to do the same. No one "must" to do anything, it's open source script. Do it and share it.

I understand your point of view but isn’t the whole thing to make it as good as possible?

There are better things to do to be honest. Not everyone use ad importer, not many people those use it, load 20 images per item, and visitors those upload 20 pictures are probably OK to wait few seconds until it get processed.

Try to play with compressor.
In oc-includes/osclass/frm/item.frm...


find this line:
}).use(Uppy.Compressor, {
I found it supports maxWidth and maxHeight, so if image is larger, it's going to convert to smaller dimension.
This can be handy if you upload image 8000x8000px, but on site you generate just 1024x768... you don't need that big one.

Change it to:
        }).use(Uppy.Compressor, {
          quality: 0.85,
          maxWidth: 1600,
          maxHeight: 1600
         
Carefully if you use "keep aspect ratio" as you might get portrait image... but if you use for maxWidth and height same value, you should be OK.
I tested it and it do compression on upload, so PHP already receive smaller image and might be faster.
This will not work for Importer as this one provides images to osclass diferently

I will try this. I uploaded 4 photos between 1,5 and 2MB with 4032x3024 and after I hit “Post” it loaded for 57 seconds! Huge time if you ask me! I will try what you suggested and let you know!

I am not speaking about ad importer only, this happens when adding a new listing, it takes 1 minute to post an ad with 4 photos of 1,5-2MB...

I added 10 images between 3 and 4 mb when adding a new listing and took 7 sec to upload them... Quality was ok with:
        }).use(Uppy.Compressor, {
          quality: 0.80,
          maxWidth: 1200,
          maxHeight: 1200


Aside from tweaking Uppy's compressor settings, the best way to speed up large photo uploads is to upgrade your server. A well-specced cloud, VPS, or dedicated server with a 3GHz+ CPU, SSD/NVMe storage, ample RAM (to prevent PHP from swapping), optimized Apache/Nginx proxy fcgi settings, and sufficient, well-routed bandwidth (especially under load or across regions) will make a difference. If you're into advanced configs, you should also look at tuning your tcp stack.

While PHP performance is mostly CPU-bound, these other factors also impact how quickly large images are processed.

Good think about compressor is that temp image is uploaded in reduced size.
Lets say your normal image size is 1200x1000, does not make sense to upload 4000x3000 image and use it in PHP. If it can be compressed on user side to smaller one, its good for your server
