I checked my result again. Build took 31 minutes. I was using an XO-4 with 2GB RAM, 4GB swap on SD card, 500GB USB HDD. My build was without Sugar activities. I was also using two performance changes: versioned_fs=0 make_tree_tarball=0 I tested the hardware to establish performance metrics: 1. internal eMMC, sequential read, 49 MiB/s, (operating system), 2. USB HDD, sequential read, 27 MiB/s, (osbuilder filesystem), 3. USB HDD, filesystem write, 27 MiB/s, 4. external SD, sequential read, 15 MiB/s, (swap), Sequential read test method for each device was: yum install -y pv pv -i 30 /dev/sda1 > /dev/null -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
Re: Seeking advice to buy ARM system.
Hi James, When I tried building on XO-1.75, it had taken several hours. I didn't know repeated builds could have been that fast. I will try doing repeated builds once again and if the build time comes under 1 hour, that's good for me . So, Using XO-4 seems like the best and safest option for me right now. @list : Thank you all very much for your candid suggestions. I appreciate it. -Basanta On Mon, Jul 29, 2013 at 7:39 AM, James Cameron wrote: > Using an XO-4 and an external USB SATA drive, my repeated builds of > 13.2.0 take about half an hour. > > -- > James Cameron > http://quozl.linux.org.au/ > -- Basanta Shrestha Network Engineer Open Learning Exchange (OLE) Nepal Tel: +977.1.551, 5520075 Ext. 303 Cell: +977.9818 605110 http://www.olenepal.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

Using an XO-4 and an external USB SATA drive, my repeated builds of 13.2.0 take about half an hour. -- James Cameron http://quozl.linux.org.au/ ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

So far I have been suggested Wandboard quad and Odriod-U2. i can tell you that OLPC will be just as interested in any data you collect. all of our ARM builds to date have been done on a donated bare evaluation mother board from Marvell, which conveniently has expandable RAM (3G, i believe) and SATA ports. i would be inclined to exclude the Odroid board based on lack of SATA, and both boards you mention are limited to 2G of RAM. but we've not done much experimentation, so they might not be completely inappropriate. the recently announced Utilite (utilite-computer.com) looks interesting, but isn't available yet, so who knows? paul =- paul fox, p...@laptop.org ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel

So far I have been suggested Wandboard quad and Odriod-U2. We don't currently support the Odriod-U2. The Wandboard Quad is likely a good start and we'll be supporting it in Fedora 20. The other one that is very similar and we aim to support soon is the Utilite [1] which is similar specs to the Quad but nicely packaged.

Seeking advice to buy ARM system.
Hi, We are considering buying an ARM system in order to build Operating System Images for XO(1.75 and 4) laptops. Currently we are doing this under virtualization environment using "Fedora-17-armhfp-vexpress" which is very slow. I am seeking some expert advice on which ARM system/board to buy from the list. So far I have been suggested Wandboard quad and Odriod-U2. Please suggest. Thank you. -Basanta ___ Devel mailing list Devel@lists.laptop.org http://lists.laptop.org/listinfo/devel
