i tak je tohle pokrok vuci predchudci R1S ktere melo "oklestene" GLAN (TX670/RX930 + TX320/RX340), tohle ma RX/TX940 na obou a 2x vice RAM
Zkoušel (či vyzkoušel by) na tom někdo OpenBSD? Sice to nemá plnohodnotný UART, ale aspoň "víceméně" 2 síťovky...
nasel sem to u Mouseru ta levnejsi verze s 2x LAN je za 5300Kc (coz je o dost vic nez i kdyby 1000Kc v CR za R2S) a tady uvadej performance "Up to 600 Mbps" (coz je max 2/3 toho co R2S)
Osobně to považuji za designovou vadu čipsetu toho SATA řadiče. Pravda je, že nevím, zda je ochota periferie k handshaku na užší šířce dle PCI-e normy povinná nebo není... a souhlasím, že v praxi je jistá leda smrt a daně.
Vídám prakticky všelijaké kombinace, které spolu nechodí. Třeba hodně nová karta (PCI-e 3.0, čip nějaký ARM-based RAID SoC) proti starému motherboardu, který umí jenom PCI-e 1.1 (tuším nějaký Intel i965). Někdy se to linkne a někdy ne...
časy kompilací jsou naprosto v normě (např. celé jádro s defconfigem [hodně modulů] za 70 minut).
Jestli máte tip na nějaké benchmarky, můžu je na tom spustit.

Tohle je s diskem WD40EFRX a btrfs. Zastavil jsem to po cca čtvrthodině, ale chápu-li to dobře, mělo by to aspoň orientačně stačit:
