...SD it could be a CPU bottleneck? Though we should also bear in mind that compression can be pipelined with writes in i) and debug info loading could be lazy in ii) (e.g. for highly compressible data we've generally seen ~10MiB/s output bandwidth on single thread i7 @3.2GHz memory to memory for zlib9 with 32KiB window, that doesn't stack up well against modern IO) How is the compression implemented in lld? Is it chunked and therefore paralellizable (and able to be pipelined with IO) or more serial? I think the intention is i) so we'd be happy to link a few of our game titles with vary...

Also not an expert, but would it make sense for this to be configurable at a fine-grained level, perhaps with another option, or an extension to the compress-debug-sections switch interface? That way users who care about the finer details can configure it themselves. And we should pick sensible options for the default.
