Blosc - faster than memcpy()
https://github.com/Blosc/c-blosc
On right circumstances Blosc is so fast that even speed ups reading data from RAM (read less, decompress in L1 and L2 caches)
As far as I can tell the blog author didn't include the 91MB file they used to test the compressors with, so I couldn't give it a try to see how it holds up. I guess 91MB would be too big anyway.
Windows shell has "Compress contents to save disk space" checkbox in folder properties. Usually, that compressed flag is inherited by new files created in a folder with that checkbox. OP can probably set the flag on Default\IndexedDB or Default\Service Worker folder and see whether this changes the results of that IO benchmark.

It's not transparent like the filesystem compression, but it offers far more potentially beneficial compression algorithms such as LZX.
