Hi, I recently bought a second hand r510 server, a 12 bay model specifically, I decided to use the two internal bays as my boot drive, so I bought two new Kingston 240gb ssds put them in raid one and installed Ubuntu 18.04 Lts on it through a microsd on a USB adaptor, I bring this up because everything was perfectly fine when using the USB installer.

But once installed Ubuntu, or at least the login screen runs incredibly slowly, it doesn't seem to be lag, as if, for instance I hold down a button on the password box it stops as soon as I stop pressing it. If it helps I could film it.

If anyone could help me it would be greatly appreciated
