anyway it is another discussion about hypervisors we made it 6 months ago,
why it is recomended to make apache and mysql in seperate servers ??
because they compete heavily for physical resources and they scale at different rates
-
ah ok, i see what you mean,
thanks -

@coliver no dear, i already tried XenSever, it consume about 700 MB,
Are you sure about that? How did you determine that it was using so much? I've never seen it grab that much.
Default is 752 MiB.

what makes apache not playing well with mysql if they are on the same server ??
They play fine, it's you we are trying to alter.

it takes 1 GB
Use the free-m command, not a graphical representation. That's not the number that you think that it is.

Ya mine's using close to 2GB
Are you sure? I don't think that tool tell syou how much is used.

That's the RAM for each VM and the host. 8% is allocated for the dom0. It's not actually using that much, but that much is allocated by default, bad wording.

No, that's not an issue. Specifically the issue is the potential to write code that relies on locality.

I mean, didi you run free to see what was REALLY used?

Used is like 702, I changed the response above.

Q: Is this assuming he has a rather large server to expand into? The differing rates can be a big problem, no? I always looked at VM's as a means to make system resources more economical.

I'm not going to be confident in that number till someone shows me the real free -m output rather than something translated for me.

Assuming two individual VMs or one with the resources of those two.

I guess this means that you just have to calculate the growth rate and account for that. I see your point.

Running local you can very easily get into doing things like copying database files, trying to look at file instead of properly database interfaces, trying to use local files instead of network interfaces, etc.

You have to do that anyway

I realized that when you made a point without making a point. I shake my head at myself sometimes

By writing your code to expect the database server to be on a different server than the web interface, it makes the system more scaleable as well... Even if you are just writing this to be used internally.

You mean because it assumes that single system running VM's will eventually not be enough, correct?
