Currently we run CF multi-server on JRun, so we have an
instance for each of our clients. For some reason, we've
always found this desirable, though we've never really seen
any clear benefits other than being able to maintain separate
CFAdmin settings and restart an instance without
Steven,
I would say that it is still quite important - especially if you wish to
leverage more memory on a larger server.

I agree with Dave. If customers feel they need control over their servers,
then they have that choice. Only other reason for mutli-instance would be
mappings / unique custom tags that they didn't want to make global and
such. I'm finding that the new mappings that you can do in CF8's

Whoa What about the ability to run your instances with different JVM
args and allocate memory and resources specifically? And what about
leveraging more than 1.6 gigs of memory using multi-instances

Yup, agreed that it should also be considered for anyone looking to setup a
multi-instance. Currently that doesn't fit our need or budget (according to
the owner). I'm just a lead developer plunking down projects for him to
cash out on. I don't get a say in hardware or software installation /

multiple instances:
- isolation of services for security/administrative reasons
- isolation of services for stability reasons
- ability to configure
to run a site that handles a lot of sessions in
CF even with multiple instances/boxes.

Right
Yep, and isn't this the biggest weakness of CF to date? Are
other technologies limited to 1GB or ram? PHP/.NET/RoR?
This is a JVM limitation, not a CF limitation. And, it's platform-specific.
The memory limit for a 32-bit JVM is much higher on, say, Solaris - around 4
GB, if I recall

The are if they are limited to pre-JAVA 1.6 (IIRC the version). The limit is
not a ColdFusion specific limit, but a limit it inherits from the underlining
Java. So any

Doesn't Java suffer from this same limitation? It is my understanding
that the memory limit is a Java thing, not a CF thing. Please correct
me if I'm wrong.

Okay, this
The 2GB address space limit only exists on 32 bit
architectures, correct? A server running lets say Windows
2003 x64 Server or any flavor of x64 Linux wouldn't have that

32bit JVM?
Maybe you should direct that question to

32bit Java. 64bit Java doesn't suffer from this limitation AFAIR.
Speaking of which, is CF certified on any 64bit java? I remember
something about it being certified on x64 Solaris or something.
Is anyone using it on a 64bit Java under windows?
Hmmm, this knowledge base article shows
