A shared object, even if mapped in 300 running apps will be loaded only once in physical memory (at least for the code segment). Statically built binaries will have each another copy of the code that will be loaded every time the binary is started. So it will be loaded in memory 300 times.
I just checked the size of the clang-10 binary that was built. It is fucking 1.9 GB big (gcc 9.2 on the same machine is 6.1 MB).

but you're comparing a debug, unstripped with a release, stripped build ! (also, 6.1 mb seems low for GCC ? the main GCC binary is cc1plus, not gcc / g++)
That's what building from source builds by default. I limited the build to X86, I don't need the cross compiling capacity There's probably a combination of options that will reduce the sizes and such, but by default it's gigabyte big binaries statically linked.
