I was just wondering if there are special tricks people do
that compile A LOT on centos? Do RAM disks help or something else I dont
about that minimizes your compile time? I presently have and AMD x2
4800+ with 2GIG ram.
Just curious if I can reduce any more time out of my compiles.

Watch out for background processes that steal
resources:
Move /etc/cron.daily/ mlocate
prelink
to /etc/cron.weekly
Remove /etc/cron.daily/makewhatis and let it only
run weekly (its already in weekly)
Open /etc/updatedb and tune it for your system:
add ntfs-3g or vfat to prunefs
If you have any mock partitions, add that to
prunepath

Title: Re: [CentOS] special tricks for developers box on centos 5
More importantly, mount your dev filesys with atimes disabled and ext3 indexing on.
Use tmpfs for /tmp, /usr/tmp, /var/tmp, it uses swappable ram filesys which helps a lot too. Make sure nothing gets put in those tmp dirs that needs to persist across a reboot and limit the max size each can take to 1/2 total memory.
More memory...
As far as background jobs go, reschedule them for day time hours when your asleep ;-)

yum install ccache
Frank - HEY that is fantastic.... Dropped complete compile from 27
seconds to 14.
I was not aware of this...

Oddly enough, a lot of people don't seem to be aware of it. I think it's right
up there with sliced bread and beer in bottles, myself. I have no idea why
it doesn't seem to have the mind-share that it richly deserves.
ccache does not appear to be part of the centos base or core or whatever you
wanna call it
I see that karan and dag have it in their space
Is there any downside to installing ccache?
If so, in what terms?
How about on an internet facing box?

I think it's just too new and shiny. ccache is installed by default with
Fedora 8.
> Is there any downside to installing ccache?
None that I've noticed myself. It can eat up a fair bit of hard drive space,
but you can set that for whatever you want and in the age of big hard drives
that's not a terribly significant issue.
> How about on an internet facing box?
I can't see how it would introduce any vulnerabilities that a c compiler
doesn't introduce on its own. But I'm not a security expert either, so what I
do I know....

Wow, fedora 8?
Where have I been?
Sheesh, most of us are still dealing with considering centos 5 migrations
from rock solid centos 4 "as necessary" eh?
Isn't this fedora thing getting a little bit "cat outta the bag" or has
there been a consensus of how many passing fedora's will make up a new
"upstream release number?"
Anyone care to share?
