<Solved>Re-visiting SSD's

[gezza]

Hi to all,
I had pclos2012.02 booting in 20 secs.
There was a problem, in that I had had my home partition as ext2.
I created a LiveCD of the system, reinstalled with home as ext4.
The system now boots in 46 secs. instead of 20.
A sata2 drive boots in 50 secs.
Could anyone explain what has happened to the system, is it changing from ext2 to ext4?
If so why is ext4 soooo slow.?
As always, your replies gratefully received.
Gezza.

Gezza,

because the "system", meaning PCLinuxOS, doesn't reside on /home (instead it live in the '/' filesystem), I would say that the fact you changed /home from ext2 to ext4 is irrelevant, and is not the cause of the slowness.

Things could be different if you formatted the '/' filesystem as ext4 instead of ext2, but consider that the performance between ext2 and ext4 is different (ext4 slower) only when writing/rewriting, and are usually equal while reading.

That said, there are no enough info to understand what is going on on your system ...

Thank you, AS
The SSD drive was formatted as ext4 '/'
ext2 '/home'
The partitions are defined in size 25Gb for '/', 35Gb '/home, all partition sizes are approx.
The hardware is as follows:---
Asus M3N78-EMH HDMI Motherboard.
2GB ram, 1st drive Corsair SDD 60GB, 2nd. drive Hitachi 2TB.
Nvidia 8400GS
AMD Phenom 8450 3 core.

---------------------------------------
The original install was abysmal, only booting in 48 secs.
A re-install worked well, booting in 20secs, '/home' still ext2.
A livecd was created and re-installed with '/home' set ext4.
Now the system is just a little faster than a sata2 drive.
Still booting in 48 secs.
There is one other thing I can try. Changing the splash screen.
At this time the splash screen is "SPEED" and resides in home.
I will change back to the PCLOS screen instead and see how that works.
Will report back after the trial.
Many thanks, AS, for your reply.

OK....
I changed back to the PCLOS splash screen with no change BUT....Why is there a delay of some 16 secs from the end of the 'boot' screen and the starts of the splash screen?
This is still on the SSD.
I will create another  LiveCD , put the original sata2 drive back in the system and then put the SSD in the sata3 system.
I was wondering if Tex was still booting in 8 Secs and if so is his system sata3?
?why do I have a 16sec delay starting the splash screen. What can cause such a delay?
Perhaps a reinstall would cure it?
Many thanks AS for your input.
