[gentoo-user] Prelink on a already fast system

[gentoo-user] Prelink on a already fast system

[Dale]

I was curious.  I have this new rig and was wondering if prelinking 
would help any.  It's a 4 core AMD 3.2Ghz CPU with 4Gbs, soon to be 
8Gbs, of ram and a SATA 3 hard drive.  On a modern system, would prelink 
make anything that much faster?  Is it worth installing in this system?

Thoughts?  Opinions?  Personal experience?

Thanks.

P. S.  Ram is ordered and should be here in a couple days.  Having 
Newegg about 100 miles away is pretty neat.  :-D

Hi,

I have U2300, 3Gb, 120gb SSD and I tried prelinkin on my system. I
didn't notice any improvement.

Best regards

I read up on what it does and I sort of think it won't make much 
difference.  I'm about to have 8Gbs of ram here and I figure it might 
help on the first load but after that, it will be cached in memory and 
very fast anyway.  I'm not to surprised that you didn't see any 
difference in speed.

I used it on a older and pretty slow rig once and it did help.  I think 
it was 800Mhz with 512Mbs of ram.  It also had some much slower IDE 
drives too.  It wasn't a huge difference but you could tell the difference.

Thanks for the reply.  Wait and see if anyone else thinks it would make 
anything faster or not.

Some of the googling I did in the wake of the glibc-2.13 debacle
indicated that prelinking makes far less difference wih newer kernels
anyway. Even the old slow box wouldn't get much benefit from it.

I disabled it because of glibc and won't be re-enabling it, but I might
give it a try on this netbook to see if it makes a discernable difference
with a slow CPU and slow drive, or I'll buy it a SSD.

Sounds like it isn't worth the trouble anymore.  I think I'll leave it 
alone.  The new ram may make some things faster tho.

Thanks.

It'll be interesting to hear whether it makes any difference. I'm sure it 
will if you're currently swapping to disk a lot (are you?), but otherwise 
only during en emerge of vast proportions. Or so it seems to me.

I've always been satisfied with my 4GB, which has always been plenty to hold 
the applications I run and their data. Except while emerging, say, Open 
Office, but I'm not going to spend even more money than I have already just to 
accommodate that!

Well, turned out my ram is coming from NJ instead of Memphis.  May take 
a extra day or so.  It did ship this morning tho.  I plan to max out at 
16Gbs and put portage on tmpfs.  That should be big enough even to 
compile OOo then.

Checked UPS.com and it looks like Friday.  Not to bad.

I live "one-day UPS ground" time from Memphis (I can drive there in
about 4 1/2 hours). It's always a sad moment when I see my order
status from Newegg and that it is not shipping from Memphis, but
California or NJ...

Well, what got me once was the trip a package took.  I ordered 
something, can't remember what it was now but anyway, it left Memphis, 
went to Atlanta and sat there a day or two, then went to some place in 
Kentucky and sat there for a day or two.  Then it went back to Memphis 
where it sat for a couple days and then they dropped it off at the post 
office to be delivered.  DHL was the one that did all the running around 
the country.

Needless to say, I wrote newegg a little note about all that.  They 
refunded the shipping, which I wasn't worried about, and said she was 
going to talk to the higher ups since they are getting a lot of similar 
complaints.  I notice that their only options now are UPS and such.  I 
don't see the so called "egg saver" anymore.

That package took over a week for me to get.  As I explained in my note 
to newegg, I could have rode a bicycle to Memphis, got the package and 
rode the bike back faster than the shipping company could get it here or 
even just get it back to Memphis to drop it off at the post office.

The funny part, once it was taken to the post office, I got it the next 
day.  So much for snail mail.  They should have shipped it with them to 
begin with.  lol

At least we know now why they went belly up.  Let's not mention the part 
from Sears that I had to drive 40 miles one way to get.  They delivered 
it to some ladies house.  She found me in the phone book.  I guess DHL 
doesn't have a phone book.  :-@  There is only two people around here 
with my last name.  The other is my brother.  He knows where I live 
too.  ;-)

I have a correction here.  It appears "egg saver" is still alive.  It 
also appears that DHL is still alive as well.  I saw on the news where 
they closed down here in the USA but I guess it was just one of their 
big centers or something.  Anyway, my 8Gb kit is coming from California 
in route to Mississippi so this may take a while.  Given their record, I 
just hope it gets here at all.  o_O

My 4Gb stick will be here tomorrow.  I also decided not to do the 
prelink thing.  Sounds like it would just be something else to keep up 
to date with little gain if any gain at all.

Since this is the gentoo-user mailing list I better explain that routing of 
parcels is performed so as to minimise journeys (hence fuel and driver costs) 
for the company, rather than minimise delivery time for the end customer.  
Usually they may delay a journey to make sure that the lorries always run full 
of goods back and forth.  Service level agreements may mean that they will on 
occasion run less full than they would like to so as to not exceed maximum 
delivery timescales.

I am led to believe that this is the case even when the goods are to be used 
on a PC running Gentoo Linux ...   ;-)

I'm aware of the way they do things and it can even make it look weird.  
Thing is, it went probably a thousand miles to end up across town if 
even across town.  For all I know, newegg and the Post Office could be 
within blocks of each other.  How they could argue that would be cost 
efficient is beyond me.  I could see one out of the way hop to their 
main hub but with them, it appears that they have many main hubs.

I have to say tho, this is not just DHL.  This is a package that is on 
the way here now.  This is so weird.  lol

It left the east coast area, went to Texas, went back to Kentucky, then 
back to Memphis and is on the way here.  Me, I would have put a 
parachute on the thing and dropped it off at Kentucky when I flew over 
it the first time.  lol   If they sort of flew to the right a bit, they 
could have dropped it in Memphis.

Oh, It left Kentucky and was in Memphis in ONE MINUTE.  If UPS has a 
plane that fast, they bought the SR-71 or something.  By my math, that's 
moving about 20,000 miles a hour.  O_O

My other package that went by DHL, no record of it being shipped yet.  
I'll start worrying tomorrow I think.

With what I got ordered and sort of on the way, I'll be maxed out at 
16Gbs and have a nice battery charger.  The memory is for Gentoo Linux 
and no idea if the charger has a OS at all.  Heck, it may.  There is a 
guitar that runs Gentoo remember?

Weird days.

I'm glad you posted this.  This helped me with another issue I been 
trying to figure out.  I checked the USE flags for nut and realized I 
had usb enabled.  My UPS uses the serial port instead of USB so I needed 
to disable that for nut.

To think ya'll thought you were being funny.  :-P

I have just upgraded my laptop to 8GB (90$ ebay ddr3).
I now use tmpfs on /var/tmp and /tmp/ and run catalyst with all sorts of
experiments.
Take care I needed to provide more inodes to /var/tmp/ . with
nr_inodes=500K,size=80%
the default was 204K.

It helps when loading the desktop for the first time.  But the 
improvement might only be one second or so total if your hard disk is 
fast, so it's probably not worth it.  I, however, find it extremely 
useful on some older machines I run as servers (older P4 CPUs ranging 
from 2 to 3GHz with 1GB RAM and old, slow IDE disks); they're running

That's sort of what I was thinking.  It may help on older machines with 
slower hard drives but not much on newer rigs with fast hard drives.  I 
have a older rig that is a AMD 2500+, 2Gbs of ram and IDE drives.  It 
might help some on it but still may not be worth it.  The drives on 
there are pretty fast for its hardware.

Thanks.

from 'man prelink'

'prelink  is a program that modifies ELF shared libraries and ELF
dynamically linked binaries in such a way that the time needed for the
dynamic linker to perform relocations at startup significantly
decreases.  Due to fewer relocations, the run-time memory consumption
decreases as well (especially the number of unshareable pages).  The
prelinking information is only used at startup time if none of the
dependent libraries have changed since prelinking; otherwise programs
are relocated normally.'

So I would not expect much gain from fast storage such as an SSD, and
also the linker would hopefully have gotten smarter as well, perhaps
making prelink redundant.  From an "average system" some time ago when
prelink first hit gentoo, it made a huge difference in startup times on
the likes of openoffice when I did timimgs.

All my systems are prelinked these days, and I have not the time to do
any tests - is someone able to do before/after tests on some common, but
slow loading apps and post here?

Settle this one way or another :)

I have a ssd.
I always used prelink.
After a botched gcc upgrade I was forced to reinstall (yeah, THAT botched).
I forgot to install prelink.
I did not miss it.
I realized that I forgot prelink when Neil started his glibc thread and I had 
a look with eix.
