So if cold booting or resuming from hibernation you're upto 17 seconds before the O/S gets a sniff!

Sorry but thats wrong....
#1 depends on settings - anywhere from 1-4 seconds so I can give you that.

but BIOS initialization takes about 3-8 seconds depending on the board.

My carPC does a full start from powerOn in 21 seconds - does that mean I have a 4sec startup?

First off, I think that "slow" is relative. To me, a 30 second wait for my PC to resume from hibernate and settle into music is not "slow. To others, it is extremely slow.
So anything we're discussing here is a purely subjective judgement.

OK. How many users are still running a Via EPA board with a C3 or C7 processor?
Compare a C3 CPU which is used in the M10000. IT clocks at 1.0 ghz, and is roughly the equivilant of a 1.0ghz P3. That's right, a P3. No typo there.

You can't compare the load time of an OS on that CPU to a system with an Intel Core 2 Duo or even an Atom. The architechture and processing capability is completely different.

And I didn't say "slow" hardware. I said "slower hardware". Hell a 7200rpm hard drive will yield faster boot times than a 5400rpm hard drive.
Why?
Because the 5400rpm drive is WHAT, boys and girls?

SLOWER HARDWARE

A PATA hard drive is slower than a SATA hard drive.
RAM modules have different timings, even though they are rated for the same speed. Never mind that RAM modules come in different speeds.
Even different chipsets utilize resources in different ways. Some are faster than others.

I can do a comparison of load times on the same hardware for all the windows front ends...would that be useful to anyone or am i gonna get excuses like "its just my hardware"??

First of all, nobody said your hardware was slow.
And is you want a true comparison of fornt-end load times, you need to do it yourself on your hardware.



Look, I've never argued the point that CF is slow to load. And I won't. I can't because everyone has a different concept of "slow". In my case, I'm going through my ritual when I get in my truck while CF loads, so I don't notice it. And I have music playing by the time I put the truck in gear, so I have no complaints.

Is CF slower to load than other front-ends? I don't know. It is not slower than SD 1.0, at least on my system. I can't compare to SD 2.0 because I never used it.

My point is that to get an accurate comparison of front-end load times, you need to do it yourself on your hardware with the way you have your system optimized and configured.
While it's highly unlikely that you could tweak WinXP to the point where you get CF to load faster than RevFE (as an example), you can tweak your system to improve load times so it won't be "slow"... Or at least not as slow...

Bull. On both points, so it makes it double bull.

Both your points are wholly dependent on setup. My DSATX starts the bootup of my system as soon as it senses power on the ACC line. There might be a delay of a quarter second or less.

My system goes through the BIOS in well under 10 seconds. And it's an older setup.

Guys ... I said most not all pc's take around 10-12 seconds to complete bios. I'm pleased you have a fast booting system ... perhaps you'd like to share details of your hardware with the rest of us.

I have 7 pc's on my bench ... all have different motherboards ... all take around 10-12 seconds before the O/S gets a sniff.

My point is choosing the correct motherboard in conjunction with using hibernation will reduce your boot time more than any software choices you may make.

i did! im serious though, his hardware is holding him back so much more then software its not debatable. even though the atom is new architecture, its designed to be extremely low power consumption (and price), at the cost of performance. in my eyes, the atom is too weak for carpc's. for some people they seem to work, but nobody ever brags about how well they perform. hell, even my core solo 1.8 ghz chip runs a steady 40-50% load while im driving (music, gps, net radio...) but one thing is for sure, it doesnt take long to load anything...

Entirely true...slow is subjective...but when you compare it to other front ends you can get an objective fast or slow relative to the group. Thats what were referring to.

Absolutely true....and your post should probably be referenced for the next user who posts a generic fast or slow question. That said I think performance in one set of hardware will be proportional to performance on another set of hardware. While yes things like differences between bus speeds, %data paged, drive seek times, etc. could all skew the results a little bit, in general a more powerful system will show a similar spread of boot times only faster and the reverse for a slower system.

Centrafuse booting in 10secs on my pc, revFE in <2 and OpenMobile <0.3 will not suddenly become revFE 15sec and Centrafuse 3sec when you run them on a system with a slower processor or hard drive. Anyone who wants to dispute that is free to post their own results to prove it.

For now, I plan on getting together basic installs of the various windows frontends for a comparison. Comparing across OS's wouldn't make sense for obvious reasons but I could certainly compare nGhost to OpenMobile on linux if anyone was interested.

NibbleIT:
I'll leave it at get out a watch with a second hand or a stopwatch or something-even on older hardware I think thats an exaggeration.

You're comparing an operating system and a front-end software. The two are completely different.
Never mind that you applied conditions to your statement.


What is so hard to understand?

You can dispute the facts, but to say it "makes no sense?"

Let me try one more time. We're talking about boot/load times? I'm saying XP can be made to boot faster than CF to load.

Fact? I've seen it.

And having seen a few centrafuse installs with 20+sec load times, the whole slower then it takes XP to boot thing could be true.

Exactly.
