Form language performance issue

Dear all,

We use Nintex WF and Nintex Form 2013.

When the user has the UK language settings in Sharepoint, there is no pbl.

When the user uses another language (French or Dutch), the Nintex forms (NewForm.aspx) takes 6 seconds instead of 2 seconds with UK.

Do you have a solution?

Should we update our Nintex ?

Thanks
