place order taking around 12sec for confirmation if jatpack is enabled

Hello,

I’m using Jetpack with Woocommerce.

After I click place order, it is taking around 12 sec to show order confirmation page. I enabled COD(cash on delivery) so there is no payment processing. This is happening only if I enable Jetpack plugin. also I disabled all options in jetpack setting but still checkout is slow.

If I disable Jetpack plugin then order processing is taking 3sec.

Could anyone please help me on this.

My site is running on dedicated server with 4GB RAM server.
php version- 7.3.23
mysql version – 5.7.31
WooCommerce and wordpress – latest version.
