If you don't need it, don't use it. I personally use it on all my devices.

42

Which build and variant?

43

i have already used zram swap in my every router (tl-wr841n v13, v11,840n v2 , v4) but it does not work at all, i also notice that after removing this i have get stable performance in my routers.

44

Can it be switched to module? Will that be a happy middleground? As a module it should be loaded automatically, if used - and you can choose to not use it.

45

I flashed OpenWrt SNAPSHOT r0+15149-28a9ac74cc but I am not sure of its origin. Might be pCloud or your Jenkins. I still have the file though, can send you if needed.

46

Can you provide the sha 256 sum of the image?

in variant 3 , stock board data not working. Need to check the difference with variant 1 and variant 2.
invalid board magic

we used the dl/google-drive/1L3phKriJCGbkdo3rrDT_MeLn_3HbKgsc/firmware/QCA9888/hw.2/boardData_2_0_QCA9888_5G_YA105.bin file provided.

Does it match?

Well, zram isn't magic. It might give you a usability edge on near-borderline systems, but don't expect miracles. The default lzo algorithm also isn't an example of performance (both in compression ratio and speed), but there are better choices.
Additionally, the zram-swap defaults are rather conservative. You might want to play with them, in addition to the vm.{overcommit,swappiness,page-cluster} parameters.

I flashed build 30 v2 just now and 5gz is working, no more reboots. Connected to my phone which refused to connect before. Range also seems to be very good. Will do further testing.

This seems a little bit too specific. The operator can configure their wireless settings after installing the firmware.

I have restored the default of adding kmos zram and zram swap. I did not see any relevant bugs at: https://bugs.openwrt.org/...?zram . If you can file a bug it can be fixed.

57

There was a bug in the builds previously with the variants. This has been addressed in build 32 onwards.

58

To remind everyone - these are automated builds w/luci of snapshots. You should be prepared for bugs. You should understand your hardware and take caution and know your recovery options.

Can we try this firmware?

If someone wants to patch openwrt, I will track their repo and produce builds as well.
