[Simh] Excessive paging of the real machine running SIMH - VAX

Greetings all

I have noticed for a while now that startingup SIM-H - VAX results in a great
deal  pagefile io on the real machine (XP-Home & Pro, 1GB real).  This always
happens just after the "Write bitmap has successfully completed." message, and
sometimes on shutdown - just before the halt message.

The vax is configurred for 128 mb & task manager shows the VM size @ 139M.  It
wasn't an issue on the home machine - it didn't take all that long to do, but on
the laptop it took a long time.  Task manager showed almost 400K of page faults
- and there was continous real disk activity for a long time.

Ini file follows

load -r ka655x.bin
attach nvr nvram.bin
set cpu 128m
set rq0 ra92
set rq1 ra92
set rl disable
attach rq0 vaxsys.dsk
attach rq1 vaxdata2.dsk
attach xq eth2
;Set console telnet=1000
set cpu conhalt
dep bdr 0 
boot cpu

Any suggestions greatly appreciated

Thanks

Villy
