Virtual memory paging speed when memory gets low might improve.Exceptionally well-engineered programs like Integrit圜hecker Java (icj), which utilize all CPU cores while overlapping I/O independently of computation (worker queues, multi-threaded file system scanning, multi-threaded parsing, etc).

The good news is that there are at least some cases where the faster speed will help: Very few tasks can process data at more than 3.3 GB/sec, so 7.4GB doesn’t mean things would go faster in any appreciable way. Adequate CPU processing power for the data stream.And most such apps read in very small chunks. that app is crude from a performance perspective. A poorly written app that reads then computes and repeats-until-done. A well-written app is already overlapping I/O and computation for an effective zero-time disk I/O (rarely could data be processed anywhere close to 3.3GB/sec, so the I/O time is effectively free). Most disk I/O is intermixed with computation of some kind.Cutting the I/O time in half might might mean very little in the overall picture, where most of the time is computational overhead of other kinds: memory allocation, data structure setup, parsing, etc.Apps that make stupidly small reads/writes might still benefit, but nothing like maximum I/O speed. using very large transfer buffers, just for starters. Whatever application is reading or writing had to have special attention paid to maximizing disk I/O speeds, e.g.Several things have to be the case for 7.4 GB/sec SSD to outperform a 3.3 GB/sec SSD on real world tasks: Transfer speed depends heavily on transfer size Application behaviors And since most apps use absurdly small buffers (1MB or smaller), they can never get full speed from the SSD. You need only glance at any of MPG’s test charts to see that transfer size matters hugely to speed. Next, a top speed of 7.4 GB/sec is *only* achieved for very large transfers. Once that cache is full, the overhead starts killing performance. How badly things are affected depends on the amount of memory 64GB will be worse than 32GB memory.

That 7.4 GB/sec quickly gets cut back by this bug, unless macOS Monterey has fixed it. What is required for 2X faster I/O to matterįor starters, macOS has a performance bug that cuts ultra-fast SSD speed in half for the very jobs that could most use the speed. The next closest thing next is a ~2.7 GB/sec Thunderbolt SSD, like the OWC Thunderblade or OWC Envoy Pro SX. To know for sure, you’d have to compare using a 3.3 GB/sec SSD, and there is no way to do that (no external can go that fast, and no other internal SSD is possible). Does it mean much of anything will run a lot faster? Nope-a little faster for some things, notably faster for a few things, and not much faster for most things. Does that mean your Photoshop files will save twice as fast? Nope.
