Dear Kevin The company I work for might be able to help get back the performance lost from the fixes for Meltdown and Spectre.
I work for Ellexus, an I/O profiling company. Our tools could help identify any inefficient I/O patterns in your applications to reduce the impact of this. We can set up demos and a free trial if you're interested in seeing what we do and how we can help.

Our understanding is that the most serious of the negative performance impacts of these patches will be for things like I/O (disk / network) ? given that, we are curious if IBM has any plans for a GPFS update that could help mitigate those impacts? Or is there simply nothing that can be done? If there is a GPFS update planned for this we?d be interested in knowing so that we could coordinate the kernel and GPFS upgrades on our cluster. Thanks? Kevin P.S. The ?Happy New Year? wasn?t intended as sarcasm ? I hope it is a good year for everyone despite how it?s starting out. :-O ?
