A lot of game-related media has reported that a lot of games are largely unaffected by Spectre and Meltdown. My impression is that the most common result is "about 3%." (With some notable exceptions, however.)
Does this bode well for Apple code, which seems to tend to pull in innovations from games into the general UI?
- alkonaut 9y agoThe performance issues come from security mitigations when entering/exiting the kernel during syscalls. So I/O heavy workloads such as databases will suffer, whereas heavy compute-oriented tasks such as games should be mostly OK. This is expected. There is nothing any company can do to "take advantage" of the fact that games are cpu/gpu bound in order to mitigate new performance issues in e.g. databases.
- SquareWheel 9y agoExactly. Though it may encourage different performance best practices now that syscalls are considered more expensive.
