Hi Everyone,
Is there anything additional required to enable better performance improvements (kernel patch for TXTS and RXTS are set to 3 each see below link) on a Banana PI running Armbian V21 / V22 ?
I have updated the bootloader, and OS, and the performance is still abysmally poor.
Mechanical or SSD drive connected to on board SATA yields a whopping 2.7-10 MB/sec write speed using dd with a large block size, or with the iozone tool ~5 upto ~45 for larger block sizes.
Still a very far cry from the ~120 after the kernel patch applied in ~2019 => https://forum.armbian.com/topic/10352-a20-sata-write-speed-improvement/
I would be happy with a consistent 10-20 MB/sec honestly...
From what I've read it was included in the kernel after v5.2 by default? Armbian R22 is presently kernel 5.15 ... So is the manual kernel patch still required, or no?
