> our early experiments show an average memory savings of 7% from this and a few other memory improvements This seems little. I wonder if they knew it beforehand and decided it is worth the effort, or overestimated potential memory savings. > Chakra was able to reduce RegExp bytecode memory in some popular extensions in this release by up to 10% Same as above. My current total size of ad filter rules is less than 1MB. Even if all of them were RegExps and bytecode representation was few times larger than raw rules, that would be quite insignificant gain.
