Yeah, I'm not surprised the PCIe 5.0 transfer speeds matched with top tier SSD chips win that race.

It still bothers me that the fastest most performant computer I have access to is almost always my laptop, and that by a considerable margin.

Someone should do some lz4 vs. ssd benchmarks across hardware to make my argument more solid and the boundaries clear.

You can get AWS instances with very fast local NVMe drives.

If you have many cores and have the right optimizations in place the bottleneck for lz4 decompression is RAM throughput which is always going to beat whatever fancy disk setup you have.

But yes on the extreme end absolutely there's a point where lz4 stops making sense, but also most of us aren't trying to max out a 128 core postgres server or whatever.
