I don't know if it's worth mentioning but you get a good 20-30% speed increase going to a 64bit host/build of SIMH, and a few more points beyond that for rebuilding most of SIMH with -O2 ... I found a couple things that broke in -O2 that work in -O1... it should have been in the simh list.

Dell Latitude E6500 (it's a Core 2 Duo at 2.5 GHz I think), running Ubuntu Desktop, Oracle VirtualBox and Ubuntu Server inside the VM, then I run SIMH inside the Ubuntu server - this way the main host OS and the SIMH install can talk to each other over the network.
I get about 7 VUPS on my Mac Mini (a 1.66 GHz Core Duo), so the 14 VUPS is about right, a 2.5 GHz Core 2 is about twice as fast as a 1.6 GHz Core...

The VAX ran at slightly lower speeds than a Pentium I at the time. Its performance got higher performance marks. Both are CISC designs that makes them comparable but the VAX instruction set was very rich and designed for 32 bit address space. The Pentium showed its heritage there (and possibly still does). I do wonder how a VAX cpu made in a current technology woulld perform.

Dell Latitude E6500 (it's a Core 2 Duo at 2.5 GHz I think), running Ubuntu Desktop, Oracle VirtualBox and Ubuntu Server inside the VM, then I run SIMH inside the Ubuntu server - this way the main host OS and the SIMH install can talk to each other over the network.
I get about 7 VUPS on my Mac Mini (a 1.66 GHz Core Duo), so the 14 VUPS is about right, a 2.5 GHz Core 2 is about twice as fast as a 1.6 GHz Core...

Cool, I now have a 14 VUPS laptop with 512 megs of RAM. Just trying to get DECWINDOWS to work, I'm assuming I can get it to display remotely even though it has no graphics hardware built in, right?

Yes, you can get DECwindows session remotely.

The amount of physical pages supported by VAX/VMS depends on the hardware.
Simh emulates a VAX(server) 3900 IIRC and you ll find information here:
http://www.compaq.com/alphaserver/vax/archive/mv3800.html
Apparently the 3800/3900 support 64 MB max.
You also need to change the SYSGEN parameter PHYSICAL_PAGES, this is not done by AUTOGEN.
Oleg suggested another .bin file that might work though IIRC it was intended to support a microVAX 3900 instead of the server model so that VMS would load with a A license. Most users don t have a B license to satisfy LMF.

I just increased the memory on one of my SIMH VAX VM's to 512 MB from 64 MB - the system boots fine but SHOW MEMORY (under OpenVMS 7.3-1) still reports 64 MB. Do I need to tell the VMS installation about the new RAM somehow? How much RAM does 7.3-1 (VAX) support anyway? Sampsa

Guys,
On the same note, my network will be disconnected some time in the near future, I've ordered a change to my DSL service (moving from two lines and a load balanced router to a single bonded connection - should increase down and uplink speeds by roughly a factor of 2).
At the moment I've only got a bridge connection to update, but anyone relying on GORVAX's MULTINET tunnel will experience some (hopefully minimal) downtime.
