Same here. I had been a loyal xpenology user since Jun's contribution on DS3615/17xs' first DSM 6.x loader, and they worked beautifully in many different hardware I've had hands on, J1900, J3455, N3x00/4X00, i5/7 4xxxes, QNAP NAS, ESXi, Nehalem/Haswell servers (PowerEdge Rx10/20s, IBM x3650-M3s), Ryzen 1700x, even on my current 9900k, they all run really well. I am also very grateful for his contributions. Currently I have it running on my R510 with 12x8 TB SATA + 2x1TB Micron SSDs as raid1 cache, an intel x520-DA1 and it performs very well.
I would also love to have it running on more than 8 cores as it would be a good kvm/qemu hypervisor as well, but for now, the R510 is running on 8 cores (the L5640 has 6c12t, so 4 vcores are sort of wasted)
