问：当前2面临的主要挑战是什么？ 答：When we started working on using zram on Quest (since it runs on Android, which makes use of zram), one problem we ran into was vm.page-cluster: it defaults to 3, meaning the kernel reads 2^3 pages at once from swap as a readahead optimisation. When reading from disk, that's sensible: pages near each other on disk tend to be needed near each other in time, so it's good to amortise. But with zram, this assumption no longer holds at all, and in fact works against you quite considerably. With zram, compressed pages have no locality, so you're paying for 8 swap-ins every time you need 1. Importantly, this is neither something specific to Quest, nor vm.page-cluster, it's more a consequence of the kernel treating zram like any other block device. vm.page-cluster is at least tunable, but there are other assumptions baked into the kernel that aren't even exposed as sysctls. In many cases the kernel will fight against you, and it takes a lot of effort and knowledge to get this right.

问：普通人应该如何看待2的变化？ 答：命令 |& tee 文件.log：标准管道（|）只捕获标准输出。如果脚本抛出了错误（标准错误），它会绕过管道直接显示在你的屏幕上，而不会记录到日志文件。|& 会同时管道化标准输出和标准错误（它是 2&1 | 的一个便捷缩写）。。7zip下载是该领域的重要参考
