• How do you go down to 2 cores?

  In our testing, for example, we found that disabling some of the Z13’s cores leads to longer battery life. Our best results were with 2 Performance-cores enabled and no Efficient-cores. With fewer cores enabled, the system doesn’t have to use as much power, so the battery was able to last longer in both the Modern Office and Gaming benchmarks of PCMark 10. Source: about 1 year ago

• I am superior.

  I don't think that a massive uptime would be something that would show in a synthetic workload, like Cinebench. Those things are very good at maxing the computing power they require. The difference with high uptime machines would probably be the time it takes for the Cinebench to actually open after double clicking the icon.PCMark might show something, since it actually measures things that are not just about raw...

• Any apps to drain a laptop battery for conditioning?

  But seriously, you could look at benchmarking tools like PCMark. Source: over 2 years ago

• Dire SMB speed with on PC to NAS

  Assuming two systems use flash storage, network bandwidth is identical and it is configured the same way, there should be an issue within the PC, either system or storage drive. Check the system logs for errors and warning events related to data transfer from/to NAS. Try to benchmark the PCs' disks using fio to confirm they have similar performance. https://github.com/axboe/fio. Source: 12 months ago

• Ask HN: What are some good resources for learning about low level disk/file IO?

  Not specifically addressing your question, but when you get to the point of wanting to start doing some experiments you may find that 'fio' [1] is very handy. [1] https://github.com/axboe/fio. - Source: Hacker News / about 1 year ago

• KVM virtual machines on ZFS benchmarks

  The dd is not a good benchmarking tool, you should use something like fio and probably tune it to use the ioengine most similar to your use case (eg. a database server will probably use some async IO interface). In your first example (with bs=1G) probably something (the guest OS, the qemu/kvm or the host OS) have split into smaller chunks anyway. Source: about 1 year ago

• SSD Sequential Write Slowdowns

  All linux tests are run with fio 3.32 (github) with future commit 03900b0bf8af625bb43b10f0627b3c5947c3ff79 manually applied. Source: over 1 year ago

• Just write the f*****g parser.

  Agree, I used flex/yacc to add an arithmetic expression evaluator to fio a few years back to allow simple math with some units in fio's job files, and for stuff like that, they're fine, but I wouldn't want to use them for a real language, the error handling is kind of a nightmare.
