RE: Current PTF groups and SPECTRE/MELTDOWN

Yes, that 3% was after installing the SPECTRE/MELTDOWN fixes. Nothing scientific, just my own anecdotal experience.


We've been on 7.3 since September.

Justin,

Do you also have the SPECTRE/MELTDOWN fixes installed?
We're also seeing an increase in CPU since upgrading to V7R3 on 2/25.
P7 8205-E6C
I'm still gathering the perf data numbers.
We're seeing an increase runtime on a batch job that talks to a remote server.
Also other variables I need to factor in.
