about DOM boot speed

[Maverick]

Hi,all

I am using XPe sp1 on my device(CPU is VIA C3 667MHZ), with 512MB PQI's DOM
and compressed NTFS. My image uses WinLogon and size is about
160MB(compressed). But it takes about 3 minutes to boot into desktop window.
After I switch to Compact Flash, the boot time is shortened to 1 minute.

I prefer using DOM on my device, but how to shorten boot time, any ideas?

Gosh Maverick, there are a lot of things that can affect the performance of
these devices. Can you obtain the specs or online docs for each of the
devices and examine things like the internal architecture, the latency
delays, the r/w performance, whether they implement wear-leveling, seek
times, data xfer rates and very importantly if there are specific drivers
you should be using instead of generic system drivers.

I'm just guessing here, but if there's no pertinent instructions that were
missed in the configuration of the devices (meaning you've properly
configured the device), then this may be by design.

I could be wrong here, but a lot more information is needed. Now, none of
this answers your other issue of how to improve performance through changes
in the runtime. Off the top of my head maybe not using compression, but then
you'd probably not fit on the DOM <grin>

Good luck.

Thanks Andy.

Acturally, I've tested the same images(compressed or uncompressed, NTFS or
FAT) on DOM and CF, which shows that the boot speed on CF is 4 or 5 times
faster than on DOM. So I guess the bottleneck is on my my DOM(PQI's
industrial 512MB)'s bad performance. Does anybody using DOM manage to boot
within 1 minute? Or recommend some other brand?
