Make the next piece of data you touch after an operation close to the one your touching (statistically, on average).
The introduction talk to this is by Mike Acton at cppcon, but Jon Blow has been harping on about it as well
- deepsun 5y agoYes, but I want it to be guaranteed, not statistically. E.g. I want to run Quake1 right from the L3 cache. E.g. with filesystem I'm sure when I read or write it, if I use regular IO operations, no mmap-ing (of course there's a lot of quirks with drive caches not respecting fsync, etc, but let's skip that for sake of this comment).
