When a user registers on our site, the transition between page 2 (where user fills in the profile details) and page 3 (uploading a profile picture) of the registration process is extremely slow (up to 50 seconds).

The site itself is optimised and a user login loads with about 12 seconds.
This is the only part of the site which is so noticeably slow.

We not not use captcha and do not require users to activate their accounts (no email verification)

Any ideas of where we can start looking?

Hi, Marc.

I enabled site debugging mode and after analysis it seems that this is caused by PayPlans extensions. Here are some printscreens that you can compare:

- this is taken from page where user confirms free subscription: prntscr.com/52jp2f
- this one is from profile fields page: prntscr.com/52jp6p
- and this one from avatar upload page:
prntscr.com/52jpc8
prntscr.com/52jph1
prntscr.com/52jpim
prntscr.com/52jpm1
prntscr.com/52jpnk

Database queries total: 37290.3 ms

This process loads very long:

Time: 37383.7 ms / 38422.7 ms Memory: 15.280 MB / 42.81 MB Application: Payplans-App-Before-Load-Apps

Also you can see how many processes are created by PayPlans.

If you want to enable debug mode by yourself, you can do that here: Backend -> System -> Global configuration -> System -> Debug System -> YES

I advice you to contact with PayPlans developers.
