The FUSE-based filesystems run into a bit of trouble here - with incompressible data, DwarFS has a hard time keeping up for some reason, despite keeping up just fine with larger random reads on the same data, and so it takes 3 to 4 seconds to run random read latency testing on the 25 GiB random file. Meanwhile, when testing random read latency in `fuse-archive` pretty much just dies, becoming ridiculously slow (even compared to DwarFS), so I didn't test its random read latency at all and just had its results put as 0 milliseconds.
