Hi,

We're configuring new server and have some questions:

-Its better Let's Encrypt or cPanel SSL?: SSL

-You recommend me install KernelCare?, because i see the update are only "virtual": kernelcare
I think will need reboot server equally for other things, for example update SO, WHM/cPanel, etc. We will have 250-300 cPanel accounts.

Thank you very much!

Hello,
KernelCare applies only critical security patches "on the fly", but new kernel features and bugfixes are not included. As a result your real kernel version stays the same.
You can (and should) update the kernel as usual. KernelCare provides only security patches. If the available kernel provides some new function or has improvements, you need to update the kernel to get it and then reboot your server. Then KernelCare will check available updates/patches for your current kernel and apply them if needed.
We recommend regular kernel updates - so that next reboot due to hardware/whatever, you are booted into a new kernel. There is no need to reboot -- and that is the goal of KernelCare.

Thank you very much, i have a last question:

KernelCare will affect to server speed or performance?. Maybe the OS need do more checkings and operations if will check 2 kernels (virtual and real).

Thanks again.

The only effect I've seen kernelcare have on a server's performance is uptime related - you're going to reboot less which means better uptime and performance if you're always using the latest kernel. As far as any other effects I've not seen any.

Thank you very much, we will use KernelCare (its free when buy Imunify360).

Have nice day!
