RE: Meltdown and Spectre - Additional PTFs released

Tsutomu:

How busy was the CPU and memory prior to the installation of the PTF?

If the system was quite busy before, that tells us one thing. If the system was not real busy (meaning over 80% CPU over a 20 minute observation) then that says something entirely different.

Hi.

We have installed the PTF MF64551.

The processing time has become longer about 3 to 4%.( MF64568 is not installed yet)

Has anyone installed it.?
