Also, are you running out of RAM? Do you have 96GB installed? I can't imagine that this whole compressed memory thing does much good for serious work. Maybe it saves the OS a GB or 2 for lightly used things that load up in RAM, but in general, if you need stuff in RAM, why would you want it compressed? Then you have to uncompress and recompress it upon every use? If that's how you cram something that needs 128GB into 96GB, its going to be painfully slow. And I don't think that's even what it is doing. This is probably a feature for machines with <8GB of RAM....

My main line of thought was that compressed memory and AppNap would help keep systems like our iMacs, which are used for light analyses by multiple users, to last longer between hardware replacements. Basically, these systems are used for small genome assemblies, light 16S analysis, Sanger sequence analysis, etc. along with basic things like using MS Office doing statistical analyses. Because most users would have multiple programs open as they work on and analyze their data, something like AppNap could help extend the usable lifespan of these systems so we don't have to buy a whole new system every year or two.
For heavier analyses we would rely on our linux clusters, so we're not trying to skimp on our computing capabilities.
And as I thought when I first posted, it looks like I'm better off waiting to see what happens with the first few point updates to stabilize the OS. I've also heard from some colleagues that some older applications that they and we use are no longer supported, so we'll have to look at whether or not we still need them and if it's worth paying for upgrades or if something else is available that we might try instead.

The field of epigenetics has traditionally concentrated more on DNA and how changes like methylation and phosphorylation of histones impact gene expression and regulation. However, our increased understanding of RNA modifications and their importance in cellular processes has led to a rise in epitranscriptomics research. “Epitranscriptomics brings together the concepts of epigenetics and gene expression,” explained Adrien Leger, PhD, Principal Research Scientist...-

Proteins are often described as the workhorses of the cell, and identifying their sequences is key to understanding their role in biological processes and disease. Currently, the most common technique used to determine protein sequences is mass spectrometry. While still a valuable tool, mass spectrometry faces several limitations and requires a highly experienced scientist familiar with the equipment to operate it. Additionally, other proteomic methods, like affinity assays, are constrained...-
