[TYPO3] sr_feuser_regiser speed issue

[Stanislav Rusnák]

Hi all.

I am experiencing problem with speed of sr_feuser_register plugin. 
Creating new account is terribly slow. Especially the part when user 
hits Create new account now! button. It lasts sometimes more than 5 
minutes to proceed to the next page. When I look to the backendend the 
account is already created and e-mail is delivered, but the Thank you 
for registration page is still loading.
I am experiencing this after I moved my page to the different domain at 
same provider.

Does anyone know what is wrong?
I will appreciate any suggestions.
