I'm not sure how the "really simple captcha" plugin is supposed to work.. but in my instance, it's writing about 20,000 files to the following folder every week...
wp-content\uploads\gravity_forms\captcha-12345678asdfghjk345678ertyu567
Maybe it's supposed to be deleting previously written files?
My systems guy says that's the reason for poor site performance.. of course I don't believe him.
Any ideas?
Depending on the performance issue you're having, I don't think having 20,000 files (or more) in a folder is going to slow the performance down. Having to scan through all those files and find the necessary one would take a little time, but that should not cause noticeable performance problems.
Since Really Simple Captcha is a 3rd party plugin, I would check their support. I did find this topic at the wordpress.org forums:
It suggests checking the permissions, and manually deleting the old files. It also had some additional questions about how old the files were, and a modification to the plugin files, which I would not recommend.
Please let us know if you need more help. The cleanup should be done by the RSC plugin, not Gravity Forms.
