What makes you think the generic trampoline code has any impact on
execution speed?

Great! Now you can go read the code (mono_arch_setup_jit_tls_data).
The change we need to do in this area are:
*) replace the use of Tls* with __thread vars, both in the jit and
*) when the above is not possible (on systems without __thread support)
add a function to the io layer to get the pthread_key_t corresponding to
the Tls id so that pthread_getspecific can be used (on MacOSX this will
enable us to save the call and inline the code directly).
