Slow php-fpm working?

Question

PHP

After deleting upload/resize_cache for the first time, the product card that is opened for the first time works out for about a minute.
At this time, the percentage is loaded by php-fpm at 100%. That is, the creation of the cache is very long.
I thought it had to do with resizing the image. I removed the pictures from the product in general (in the announcement too). I clear the cache again. I reopen the page. 30 seconds.
Enabled slow log to turn on after 20 seconds (by the way, it doesn't matter if 5 or 60 output is the same) in the php-fpm pool.

And here's the layout:

This appears in the log immediately after 20 seconds (request_slowlog_timeout value). The page loads after 25 seconds, nothing is added to this log.

Answer 1

This is the cache of resized images and it takes a long time to generate it. Possibly a slow disk subsystem. Perhaps the pictures are huge + watermark overlay.
Look at the page there are pictures shown from upload/resize_cache
In general, open the template and result_modifier.php of this component and see what kind of code it is.
