Slow php execution of pinterest code

Hi,

The Pinterest Plugin is causing major performance issues and it seems without a good reason. I checked with a code profiler where the issue lies. You can see all my findings in the google drive link attached.

The plugin slows down the front end of the shop. I also disabled all plugins for testing purposes and the issue is still present. It has something to do with hashing the password on all requests. This should be definitely cached and done only once. Also the time it takes is very abnormal almost 200ms on local m3 MacBook machine.

These are the files:

pinterest-for-woocommerce/vendor/defuse/php-encryption/src/KeyOrPassword.php@104

pinterest-for-woocommerce/vendor/defuse/php-encryption/src/Crypto.php@309

Please review my findings and improve the plugin. It is a shame for such a plugin to break so many user’s sites.

Hi @igyhere,

I can understand how frustrating this situation must have been for you and your users. Just to clarify, sometimes plugins like the Query Monitor can report execution times inaccurately, as they don’t always account for server resources, internet speed, or potential conflicts between plugins and themes.

There are cases where a plugin might seem slow because it’s conflicting with another plugin or theme.

The first two links you shared don’t seem to be working, so I’m not sure what you wanted me to see. If you could share clickable links, that would be great.

From the screenshot you provided, it looks like you’re using the Query Monitor plugin, and based on what I see, the execution time appears to be fine.

Hi thanks for taking a look.

The first two links are not links but names of the files of your plugin that are flagged to cause the performance issues. This is to help you figure out a solution quicker and easier.

The performance difference was also checked using a performance analyzing tool that profiles code execution and checks what is taking long. The result can be seen in the google drive folder I linked.

I get stable results when testing with and without the plugin and too much time is added by your plugin. I am sure that the Pinterest tech team will be able to check that themselves. The problem will occur once authorized via email and password on the plugin configuration steps.

Also, there is nothing conflicting here no plugins and no themes. These are internal files of the Pinterest plugin that run some encryption and decryption on every page load which takes 200ms!

Please look into the performance of the plugin.
