I was installing centos 5.3 x86_64 on a sempron 2.7G machine with 512M ram. The install started off fine then REALLY SLOWED down about 70% into install. I did have a swap space. after that it just crawled. I tried restart the install a couple times at 512M. Same thing around 70% the slow down.
I then put in 1G of RAM and everything zipped on past and finished fine.
Does 5.3 have minimum installation RAM requirements? I had not noticed. Does the same apply for running? 5.2 did not seem to have any issues running in 512M that I recall.
Thanks for your comments.

It depends on the amount of packages you select. A minimal install should work with 5.3 and 512 MB of RAM.
The reason is that yum needs a lot of memory when doing dependency checking etc.

"Minimum requirements" and "Usable system speed" aren't necessarily the same.
The latter is subjective and varies user to user. The former is simply a binary yes/no type of operation answering the question "Can the installer complete successfully"

What do you consider to be really slow? One thing I've def. Learned with installing Linux, windows, OSX, anything that has a click-click-click install procedure, what ever the bar says, (70% complete or 20 mins left, depending on whose OS), it's LYING! Better set the installer go and grab a beer or two. Come back in an hour, one of two things will have been realised. One, you've just had a fun hour, got a bit drunk, and to top it off, you have a working CentOS installation! Or two, you forgot to click on the final button to get the install up and running, and now in your semi drunk state, you click it, and go off and have another two beers! When you come back.... Voila! A new clean virgin CentOS install!
If the above two scenarios didn't work out, then I'm guessing you got a problem with hardware, because CentOS 5.3 has installed for me on a machine, with 256M memory, and 20G HD - check console output, to make sure there isn't any errors, like maybe drive seek errors on your CD/DVD - Man, that has happened to me before, took 3 days to realise! I thought it was busted hard drives. (I was young... and stupid!) Now that I'm older, and probably just as stupid, I look out for these things.
Sorry for rambling, we have an open bar in my office, and umm... we're making use of it!

Why can't more manuals be written like this???? ;-)

5.2 is quite slow on low memory during installation as well, I run many VMs with 64 or 96MB of memory, but I always jack it up to 1GB for the install, then lower it afterward.

I've installed CentOS 5.3 on a Pentium III (500 mhz) with 384 Meg of RAM. I usually install over the Internet, so I assumed the installation was slow because of the mirror I was using. But I've noticed that CentOS (and Red Hat) are generally on the slower side of Linux installations anyhow. I've never had it come to a near stop, however.
Just realized... my laptop uses 512 Megs of RAM and it installed about as fast as my Desktop with 1 Gig (the laptop is a 1.4 Ghz Pentium M, the desktop is a 2.8 Ghz Pentium 4) so I'm not sure what was happening in your case.
