We're currently using zlib compression level 9 when creating the symbols archives. My measurements show this wastes a lot of CPU for minimal space savings. Patch forthcoming.

On my i7-6700K time and size for the full zip archive for a Windows
debug build is as follows:
Time Size
Before: 25.4s 278,708,278
After: 13.0s 280,623,521
Anything lower than level 5 and the archive size starts increasing by
several megabytes. Level 5 is definitely the sweet spot.
