Using 4Gb of ram with Erlang VM
Fri Nov 4 16:53:09 CET 2005
This is for M$ Windows versions that support the 1+3Gb memory model:
1 - enable use of the 1+3Gb model by adding the "/3Gb" switch in the file
boot.ini file usually found on C:\ ( its has the hidden attribute set
= invisible )
2 - patch the PE-header of the erl.exe file to enable use of the same model
As far as I know the erl.exe file is not linked with these attributes
will only allow use of 2 GB.
I did this a while ago when trying to push the ring-benchmark. I had a PC
Win XP Pro and 4Gb of memory. Got 1800000 processes running before
swapping (?) killed it.
