Thanks to a few of your post I was able to build the kernel, enable the zram module, and push my clocks to 2016/1512MHz. That little bit of speed boost sure did help my plex server. I was seeing transcodes for a 1080p file doing 0.9. Now I am seeing 1.1, which is enough for real time encoding. I know this likely won't apply to all the files plex tries to transcode, but the little bit of performance boost is still encouraging.

Pleasure. Yup 2 weeks ago I had never compiled a kernel, now I am compiling 2 or 3 times a day playing with options (and breaking quite a few things!) I guess my main advice would be to take care of your .config: sometimes I have got carried away with too many changes at once and then struggled with a barely working machine to recover.

What kernel are you playing with? I am playing with 4.18 and one unresolved issue is the scheduling tends to favour the A53 cores. But I have been running the A72s at 2108 with no noticeable problem - cpuminer ran fine for 10 minutes (via sbc-bench -T 70) without hitting 80C and obviously loads all the cores, as does a full kernel compile for about 25 minutes.
  • ROCKPro64 v2.1 2GB, 16Gb eMMC for rootfs, SX8200Pro 512GB NVMe for /home, HDMI video & sound, Bluetooth keyboard & mouse. Arch (6.2 kernel, Openbox desktop) for general purpose daily PC.
  • PinePhone Pro Explorer Edition, daily driver, rk2aw & U-boot on SPI, Arch/SXMO & Arch/phosh on eMMC
  • PinePhone BraveHeart now v1.2b 3/32Gb, Tow-boot with Arch/SXMO on eMMC
