Hello @upola,
Thank you for sharing the form export file.
When testing it on a lab site, I’ve noticed the delay as well. But it worked much faster after changing your current redirect URL to my localhost page.
Redirecting takes some time for the browser to execute it, but there are no issues with the form which could be related. The main reason seems to be the server response time, and redirects that happen on the target page.
The first thing you can test, is adding the trailing / to your URL in After submission, by changing /thank-you to /thank-you/ in order to save some time by eliminating any subsequent redirects.
If the “Thank you” page is still slow, you can try improving the loading time with a caching plugin (like Hummingbird, etc.), enabling server caching, or connecting your site to Cloudflare CDN.
Another alternative would be to use an inline message, instead of redirecting to a page.
Hope this helps. Please let us know if you have any further questions.
Best Regards,
Dmytro
