Note - super-linear scaling of behavior above 1000 binder objects.
Because we see this scaling in both RPC binder and kernel binder (but to
a lesser extend in 'rpc' - ignore 'rpc_tls' which has a lot of extra
overhead), this indicates that part of the nonlinearity likely comes
from userspace code OR RPC-binder itself has non-linearity similar
to the binder driver.
