J1900 Performance

J1900

J3455 Comparison

J3455 ESXi 6.7 + Windows 10 1GB on SSD datastore reads at 60MB/s while DSM 6.1 2GB with ASMedia passthrought gives max speed at 110MB/s to J1900 over Netgear R6400.

Windows 10

BareMetal Windows 10 files read at 110MB/s.
After Hyper-V installed, dropped to 60MB/s.
Hyper-V supports only DSM5.2 but not DSM 6.1 so no nfs mounting allowed.

BareMetal Windows + Virtual Box 6 installed still reads at 110MB/s with no performance loss. Virtual Box 6 supports DSM 6.1 but even though using Virtual Box raw disk, DSM 6.1 writes speed at only 20MB/s and fluctuates from 5MB/s to 30MB/s.

DSM 6.1

BareMetal DSM 6.1 reads at 110MB/s while sync data from J3455.
But DSM VMM Windows 10 reads at 15MB/s and Windows UI response slow.

ESXi 6.7

Uploading Windows 10 iso file 4GB to ESXi SSD datastore seems slow.
Windows 10 first installation feels slow.
Windows 10 2CPU 2GB on ESXi 6.7 SSD datastore reads J3455 at 55MB/s, not too bad.
