Bigmem support (4 gigas) is stable?

2001-06-13 Thread Miquel Colom Piza

Hello

I should add 1 giga of RAM to a machine which already has 1 giga. I know
I will have to configure bigmem support in the kernel (2.2.19). I would
like to know if this option is considered really stable and tested or I
can expect some problems, because this is a heavy loaded critical server
and in case of doubt I'll habilitate another server instead of  giving
more RAM to the one I already use.

Thanks in advance

Calculation of private memory of processes for estimation of RAM in big server

2001-06-11 Thread Miquel Colom Piza

I would like to know how to calculate the amount of private memory (i.e.
memory used only by that process) so I can estimate the total amount of
RAM I have to put in a heavy loaded server.

In Sun Solaris I use a tool called pmap that gives me a resume of the
private and shared memory and the size image of each process. This pmap
utility uses the /proc filesystem to obtain the information.

In Linux I've used ps axl and I think that the RSS column is the right
one, but I'm not sure. Also I've look at the file
/proc//status that has, for example,  these lines:

VmSize: 1144 kB
VmLck: 0 kB
VmRSS:52 kB
VmData:   28 kB
VmStk: 8 kB
VmExe:56 kB
VmLib:  1024 kB

But again I'm not sure which one of these numbers is the one to look at.
Could please
any VM guru help with this?

Re: 2.4.5 VM

2001-06-01 Thread Miquel Colom Piza

This is my first email to the list. I'm not subscribed but I've read it
for years.

I don't agree with those claiming that 2.4.xx is bad or still beta.

We the administrators have the responsability to test early kernels and
send  good bug reports so the developers can solve the bugs. That's the
way we can contribute to the community.

But it's really risky to use these kernels on MAIN 24x7  production
servers.

This has been true for 1.2.x  2.0.x  (I think that was the best linux
kernel series) 2.2.x and 2.4.x and will be for 2.6.x also

Given we know that the support  from open source developers is clearly
better than commercial contract supports, I don't see the reason to
complain about the work of those wonderfull hackers spending their spare
time coding for all of us.
