I have tried it but my setup is way too variable to allow me to compare performance changes. For “guix build bwa” when “bwa” has already been built I get waiting times between 6 and 42 seconds. Any improvement would disappear in this terribly wide range. I will soon have access to a new NFS share on a separate server and with disabled read timestamps, which I hope will be more reliable. -- Ricardo GPG: BCA6 89B6 3655 3801 C3C6 2150 197A 5888 235F ACAC https://elephly.net
