Possibly the same symptoms don't exist on 128MB RAM devices. Also, I'm not seeing a consistent result on the 64MB device I'm testing. Multiple reports of 64MB RAM devices being mostly unusable: Ref: https://github.com/openwrt/openwrt/pull/1077 "The default setup of the OpenWrt snapshots is more or less unusable on ath10k devices with 64MB RAM (which is a common configuration for cheap ath79 dual-band devices). How do you suggest we proceed?" Comparable results between above and my 64MB device. However, if the sleep time is extended the consumption is more--but doesn't seem to be predictable. In the original post of this thread, free went down below 8M, consuming almost 30M of RAM. I suspect this is not the intended behavior. 19:54:32 up 33 min, load average: 0.00, 0.00, 0.00 DISTRIB_ID='OpenWrt' DISTRIB_RELEASE='19.07-SNAPSHOT' DISTRIB_REVISION='r10779-d2d12346e8' DISTRIB_TARGET='ar71xx/mikrotik' DISTRIB_ARCH='mips_24kc' DISTRIB_DESCRIPTION='OpenWrt 19.07-SNAPSHOT r10779-d2d12346e8' DISTRIB_TAINTS='no-all' up: Mem: 59264 14844 35240 108 9180 28124 dn: Mem: 59264 14672 34696 116 9896 27964 up: Mem: 59264 22564 26800 116 9900 20072 dn: Mem: 59264 14720 34644 116 9900 27916 up: Mem: 59264 22500 26864 116 9900 20136 dn: Mem: 59264 14688 34676 116 9900 27948 up: Mem: 59264 21964 27400 116 9900 20672 dn: Mem: 59264 14688 34676 116 9900 27948 up: Mem: 59264 22328 27036 116 9900 20308 dn: Mem: 59264 14688 34676 116 9900 27948 up: Mem: 59264 22444 26920 116 9900 20192 dn: Mem: 59264 14688 34676 116 9900 27948 up: Mem: 59264 22552 26812 116 9900 20084 dn: Mem: 59264 14684 34680 116 9900 27952 up: Mem: 59264 22512 26852 116 9900 20124 dn: Mem: 59264 14680 34684 116 9900 27956 up: Mem: 59264 22480 26884 116 9900 20156 dn: Mem: 59264 14704 34660 116 9900 27932 up: Mem: 59264 22556 26808 116 9900 20080 dn: Mem: 59264 14692 34672 116 9900 27944 up: Mem: 59264 22588 26776 116 9900 20048 dn: Mem: 59264 14704 34660 116 9900 27932 Consuming ~23MB (~35M starting point): root@OpenWrt:~# wifi up; for i in $(seq 1 100); do free | grep Mem ; sleep 20; done 'radio1' is disabled 'radio1' is disabled Mem: 59264 21568 27784 116 9912 21064 Mem: 59264 23216 26136 116 9912 19420 Mem: 59264 27664 21688 116 9912 14972 Mem: 59264 32112 17240 116 9912 10524 Mem: 59264 32112 17240 116 9912 10524 Mem: 59264 32164 17188 116 9912 10472 Mem: 59264 32208 17144 116 9912 10428 Mem: 59264 32240 17112 116 9912 10396 Mem: 59264 33456 15896 116 9912 9180 Mem: 59264 35144 14208 116 9912 7492 Mem: 59264 36680 12672 116 9912 5956 Mem: 59264 38024 11328 116 9912 4612 Mem: 59264 39276 13796 116 6192 5196 Mem: 59264 40600 12472 116 6192 3872 Mem: 59264 40612 12460 116 6192 3860 Mem: 59264 40408 12664 116 6192 4064 Mem: 59264 40260 12812 116 6192 4212 Mem: 59264 40372 12700 116 6192 4100 Mem: 59264 40664 12408 116 6192 3808 Mem: 59264 40516 12556 116 6192 3956 Mem: 59264 40440 12632 116 6192 4032 Mem: 59264 40580 12492 116 6192 3892 Mem: 59264 40664 12408 116 6192 3808 Mem: 59264 40760 12312 116 6192 3712 ... _______________________________________________ openwrt-devel mailing list openwrt-devel@lists.openwrt.org https://lists.openwrt.org/mailman/listinfo/openwrt-devel
