RE: [[cobalt-developers] Maximum Ram on Raq 3i ?]

["Brian TerBeek" <bterbeek@xxxxxxxxxx>]

Hi..
I do not how to configure this, but each site will hold static pages in
memory
ready to be sent out. The amount of memory per site should be able to be
configured.
Anyone know the answer to that. I used to use netscape suite spot servers
and
that is another animal altogether, however it was easy to control memory
usage
for each site being hosted.
Regards
Brian

512Mb is pretty large anyway, but considering Linux uses Virtual Memory,
maybe
you won't get such a great speed increase by just plugging-in extra memory.
I've ported things to the Mac, which has awful memory-handling, and noticed
a
few things about performance:

Using virtual memory really slows things down.
A disk cache really speeds things up.

Why not create a RAM disk and, where possible, set file cache options on the
programs you're using to point to this.
This will make oft-used files really zoom.

Some software may be using very inefficient code to read/write data (eg
reading/writing single bytes at a time), and here using a RAM disk will make
an incredible difference to the speed.

Hope this helps,

A couple of questions I also have which might also be useful for you are:

Where can I get an external RAM disk for a RAQ (or just something that plugs
into an ethernet connection and looks like a normal hard drive)?

Is there some GUI utility to tell me in real-time how much RAM/Virtual
Memory
each process on the RAQ is using?



PS on the subject of RAM disks, take a look at:

whilst this mentions the Mac most the the content is of general use.
