I have a simple event registration site which uses GravityForms, GF PayPal Add-on and the GF Constant Contact Addon (all current versions). The only other plugins are the Yoast Google Analytics and TinyMCE Advanced. On ZippyKid.com, I've had a recurring problem where my forms take up to 1 minute to process (i.e. transfer to PayPal) when the user clicks submit. Even the very simple contact form had this same delay. ZK support has been able to get the current forms to perform as expected (1-2 seconds). However when I add a new form the problem appears again for that form. Obviously this is not desirable. Here is what ZK is telling me:
"The reason these are submitting rather slowly is the captcha verification."
"there is a problem with either another plugin or the theme"
"I will be talking with one of our DB admins in the morning to see if he can help me figure out why the database process is sleeping on some form submissions."
"I am unable to figure out exactly why this is or why gravity forms is having the tables sleep."
As you can see, the common thread that runs through these responses is that the problem has something to do with my plugins and/or theme (I'm using WooThemes) and not their servers. However I can run virtually the exact same forms (export/import with very minor changes) run on WPEngine and Synthesis without a hitch.
Anyway I'm not asking you to offer a solution. That needs to come from ZippyKid. I suspect that the probelm has nothing at all to do with Gravity Forms. I'm just a little shocked that a highly-regarded WordPress hosting company would suggest that it might. If GF was misbehaving why aren't other ZK users having the same problem. Or are they? I couldn't find any issues with ZK raised in the forums. Any light you can shed on this would be helpful. Thanks!
