It's unfortunate that my proposed topic for LSFMM was pre-empted by the zsmalloc vs zbud discussion and zswap vs zcache, because I think the real challenge of zswap (or zcache) and the value to distros and end users requires us to get this right BEFORE users start filing bugs about performance weirdness. After which most users and distros will simply default to 0% (i.e. turn zswap off) because zswap unpredictably sometimes sucks.
I'm not sure we can get it right before people actually start using it for real world setups, instead of just running benchmarks on it. The sooner we get the code out there, where users can play with it (even if it is disabled by default and needs a sysfs or sysctl config option to enable it), the sooner we will know how well it works, and what needs to be changed. -- All rights reversed -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@xxxxxxxxx.
