There has been a lot of speculation that the software patches to OS’s to address the Meltdown, Spectre could result in a 30 percent performance decrease . The update installed on my laptop on Jan 3rd and the results are..
that there does NOT seem to be any performance hit.
The processor on the laptop is an Intel chip
2.80 gigahertz Intel Core i7-2640M32 kilobyte primary memory cache256 kilobyte secondary memory cache4096 kilobyte tertiary memory cache64-bit readyMulti-core (2 total)Hyper-threaded (4 total)
The machine has 8GB of memory installed. I push it pretty hard with a lot of open apps and windows plus I am usually running Oracle VMWare running a Linux VM. Unfortunately I did not benchmark the system before the update.
Summary:
It appears that, if this is the update to address the Meltdown/Spectre vulnerability, I can definitely live with the performance hit.
