10:42 <samael> hello. given my application may occasionally be in shortage of ram on a bbb, shoud i enable zram swap? would it be of benefit instead of swapping to a classic swap file on the emmc?

10:44 <samael> i see the standard images come with no swap enabled. hence i wonder if there's some issue or drawback that i am not aware of in using some kind of swap

10:47 <Shadyman> samael: not sure, might just be eMMC wear that it's trying to avoid

10:48 <Shadyman> just a guess though

10:49 <Shadyman> I'm sure someone more knowledgeable than I will chime in once they're awake :)

10:55 <samael> Shadyman: yeah that's a concern for sure. hence the question: why not use zram? i can't seem to find any pointer on the web, but maybe someone did it already and found it not practical on such a cpu

10:55 <samael> i'm just asking to avoid reinventing the wheel

23:38 <zmatt> samael: if that makes sense for your use-case then sure you could enable zram

23:39 <zmatt> what are you doing that requires so much ram?

23:42 <zmatt> you mean zswap I assume?

23:42 <zmatt> ah no zswap still uses swap but with a zram cache

23:45 <zmatt> samael: generally people doing stuff on embedded systems rarely need such a large amount of ram (unless you're doing stuff with video or something, but that will suck on a bbb anyway) and attach more value to the absence of unpredictable performance drops caused by swap

23:47 <zmatt> and the wear it would cause on eMMC/SD is also a concern obviously (especially eMMC since it is non-trivial to replace)
