Tweet-sized explanation of Foreshadow: Intel chips with speculative execution erroneously use OS-private bits of not-present page table entries as physical addresses, allow reading L1-cached data from resulting location via timing side-channel.

But my S1260 is only something like 2-3x slower than the i7-6600U I replaced with it. GCC builds aren't fast, but not painfully slow either.
