The more likely answer is that it's either of: - yes, zlib uncompression is noticeable in profiles, but that the cold-cache access is simply the bigger problem, and getting rid of zlib just moves the expense to whatever other thing that needs to access it (memcpy, xdelta apply, whatever) or - I don't know exactly which patch you used (did you just do the "core.deltacompression=0" thing?), and maybe zlib is fairly expensive even for just the setup crud, even when it doesn't really need to be. but who knows..
