Kinda? it depends. Basically all modern CPUs have compression hardware acceleration or idle cores, though so sometimes disk compression can have little to no impact on your OS’ speed but increase the bandwidth of your drive by a lot. Hard drives and SSDs are half simplex, so reducing nuisance reads by 10% can make your drive appear faster at both reads and writes.
As an aside, this is why I like ZFS so much. Part of what makes ZFS great is the ARC cache with smart eviction. Most Frequently/Recently Used (MFU/MRU) allows for repeated reads from the same info to come from RAM and not a slow pool. It opens up all of that available bandwidth and IOPs for writes if you need too, or for aggressive prefetching.
