I decided to do an experiment making an os x mavericks bootable dvd and i successfully made it and boots from it using the following method

1. i made a small 8gb partition on my external 1tb hdd and used the following command to make a bootable mavericks partition:

8 GB USB drive should be called Untitled and formatted as Mac OS Extended (Journaled). The installer should be called Install OS X Mavericks.app and should be in your Applications folder.

Run this in terminal and wait about 20 minutes:

sudo /Applications/Install\ OS\ X\ Mavericks.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ Mavericks.app --nointeraction

You should see something like this:

Erasing Disk: 0%... 10%... 20%... 100%...
Copying installer files to disk...
Copy complete.
Making disk bootable...
Copying boot files...
Copy complete.
Done.

2. i made a new image in disk utility from the install os x mavericks partition
3. i burned it to an 8.5 gb dvd and booted from it

the problem was that when i booted from the dvd it took 1hr and 7 minutes to boot and it was so laggy

then i tried booting from the hdd partition and it took 53 seconds and didn't have any lag

is it normal to take that long to boot from dvd or did i do something wrong or is there something wrong with my MBP
i was using an early 2011 13 inch macbook pro with 8gb ram and 1tb hdd

Absolutely normal for Joliet file system. It can not handle the amount of reading processes of new installers. Time to die

I have heard that the OS X install, since Lion, is just not optimized to boot from a DVD, and that Mavericks is much worse. Your report bears that out.
It's interesting as an exercise in uselessness :D
Much better is to use an 8 GB flash drive, as many users do.
You then have media that is much more durable/reliable - faster, too...

I predict that in the next OS X version or two, you may see the elimination of driver support for booting/installing from optical media.
Even now, a few relatively minor scratches on the optical disk can make it stop booting completely. That's too much aggravation to even try for an optical disk installer.
 
Can you actually install mavericks from your dvd?

Last time I tried to make a bootable dvd installer from the createinstallmedia command, I too could boot from it, but it wouldn't let me install mavericks.

So that DVD went in the bin and I proceeded to make one that actually works properly using the following method.

After downloading the Install OS X Mavericks.app file from the Mac App Store, run these 12 commands in Terminal to create a Mavericks.iso file and then burn it to a dual layer DVD with Disk Utility. You may then boot up from it by holding the option key down and then install mavericks. This will not install a recovery partition. To do that, uncompress and run the script file https://dl.dropboxusercontent.com/u/13872235/Musings/Recovery Partition Creator 3.7.zip

hdiutil attach /Applications/Install\ OS\ X\ Mavericks.app/Contents/SharedSupport/InstallESD.dmg -noverify -nobrowse -mountpoint /Volumes/install_app

hdiutil convert /Volumes/install_app/BaseSystem.dmg -format UDSP -o /tmp/Mavericks

hdiutil resize -size 8g /tmp/Mavericks.sparseimage

hdiutil attach /tmp/Mavericks.sparseimage -noverify -nobrowse -mountpoint /Volumes/install_build

rm /Volumes/install_build/System/Installation/Packages

cp -rp /Volumes/install_app/Packages /Volumes/install_build/System/Installation/

hdiutil detach /Volumes/install_app

hdiutil detach /Volumes/install_build

hdiutil resize -size `hdiutil resize -limits /tmp/Mavericks.sparseimage | tail -n 1 | awk '{ print $1 }'`b /tmp/Mavericks.sparseimage

hdiutil convert /tmp/Mavericks.sparseimage -format UDTO -o /tmp/Mavericks

rm /tmp/Mavericks.sparseimage

mv /tmp/Mavericks.cdr ~/Desktop/Mavericks.iso
 
I remember making a Lion installer DVD in 2011. The DVD just continued to spin and would not boot within 30 minutes, so I just cancelled the whole thing and made an USB installer. Much quicker for peace of mind!

I guess something changed within the installer parameters that makes DVD loading that much more slower. Perhaps the Recovery Partition? In Snow Leopard and earlier, there was no Recovery Partition - everything was integrated, so perhaps that sped up the DVD boot process?
 
I don't have a problem with the DVD taking longer than a USB to boot up.

If you used createinstallmedia to make the DVD, it is more of a problem that it won't actually let you install mavericks after it has booted. There isn't much point in having a bootable DVD installer if it boots but doesn't actually let you install mavericks.

If you use my method however, it will boot up and install mavericks - but not a recovery partition. You can use the script file I linked to earlier to make that. Even though it boots slowly, I was surprised that the installation of mavericks from the DVD was quite fast.

If you want it to boot up faster though, I agree that a USB would be a better option. And it will automatically install a recovery partition if you made it with createinstallmedia - so no need for a script file in this case.
