The upcoming release of OpenBSD 7.3 is still some weeks away - it should appear around end of March IIC - and I also wanted some diversion from OpenBSD/sgi, so I did show my other machines some love in the meantime and tested NetBSD 9.3 on them. I tested a lot of machines and configurations so far for diskless operation and will list them here, starting with my SPARC machines today:

• NetBSD/sparc
  • Sun SPARCclassic w/microSPARC running at 50 MHz and 80 MiB of RAM - actually this one here:
    
    
  • Sun SPARCstation 10 w/2 x SuperSPARC SM61 running at 60 MHz and 512 MiB of RAM
    
  • Sun SPARCstation 10 w/1 x HyperSPARC HM150S-512 running at 150 MHz and 144 MiB of RAM
    
  • Sun SPARCstation 20 w/2 x HyperSPARC HM150S-512 running at 150 MHz and 288 MiB of RAM
    
  • Sun SPARCstation 20 (same as above) w/1 x HyperSPARC HM100W-256 (two processors on one MBus module) running at 100 MHz and 288 MiB of RAM
    
  • Axil 311 w/2x SuperSPARC SM50 running at EDIT: 50 40 MHz and 368 MiB of RAM
    
  
  All of them worked well and stable - even swapping to a NFS swap file didn't bother them - but overall the *SPARC driven machines felt slow, even the SPARCstation 20 when using two HM150S-512 (see The Rough Guide to MBus Modules for details about the nomenclature). The ones w/o L2 cache were exceptionally slow, they even take much longer than the other machines to actually load the kernel over NFS during bootup. I didn't test though if this would improve with a 100 Mbps NIC. But if you imagine that these ran GUIs in the 90ies...
  
  I took the opportunity and also ran some benchmarks on all of them (with 7za and openssl). I plan to gather the results in a usable form in the future (thinking about R scripting and plotting) to avoid spreadsheet software.
