Maybe I'm odd, but boot time is almost completely unimportant to me.I never reboot my desktop and my laptop goes on suspend 49 times out of 50. It's impressive that they have boot time that low now though. Eric John Stoffel wrote: > Mike> all good info. > > Thanks. > > Mike> bootchart doesn't seem to work at all for me.

holy penguins!! my average boot time with various forms of ubuntu on disk or USB thumb drive is about 1 minute. Moblin is 30 seconds!! I'm impressed now.

all good info. bootchart doesn't seem to work at all for me. I apt-get install it which is fine but it configures itself to use /sbin/bootchartd which doesn't get installed. Kind'a weird. Maybe i'm missing something. Moblin is not debian based so I know I'd miss my apt, but I'll give it a shot at some point I'm sure. ________________________________ From: John Stoffel <john(a)stoffel.org> To: Worcester Linux Users Group <wlug(a)mail.wlug.org> Sent: Thursday, February 12, 2009 10:14:21 AM Subject: Re: [Wlug] Lenovo S10 Netbook >>>>> "Mike" == Mike Leo <mleo963(a)yahoo.com> writes: Mike> Short of compiling my own kernel (which I never can seem to do Mike> right), any other advise on how to speed up a netbook's boot Mike> time?

Lenovo S10 Netbook

by Mike Leo

I picked one of these up at Circuit City last week and am looking to speed it up where ever possible. (Reviewed below). It has a normal SATA II drive in it and I know an SSD drive would significantly speed it up, but don't want to spend any more $ on it. http://www.trustedreviews.com/storage/review/2008/05/08/OCZ-64GB-SATA-II-SS… has pretty graphs to compare. I weaseled a RAM upgrade out of my hard ware guy so I have 1.5gigs in it now (max'd). I ran speed tests between booting off the SATA II drive and the same install via USB 2.0 thumb drive and boot times were around 50 seconds for either. I know there are SSD ExpressCards for cheap (http://www.newegg.com/Product/Product.aspx?Item=N82E16820191057) but I read that the ExpressCards are really just USB 2.0 speeds anyway so I wouldn't see any difference from my thumb drive test. Short of compiling my own kernel (which I never can seem to do right), any other advise on how to speed up a netbook's boot time? I will say once booted, everything runs pretty well, though I'm sure I wouldn't mind more speed then, too! grazie! Mike Review: Stopped in to Circuit City today and (impulsively?) bought a Lenovo IdeaPad S10. I've been looking for something to waste my money on/replace the Dell I bought that I ended up not liking and turning over to my wife, so it wasn't extremely impulsive, just a little impulsive. Anyway, it was 10% of the normal price, which brought it down to $370. Not a great deal at that price since online it is like $350 or so, but the one I got has twice as much RAM and hard drive space as online numbers, plus no shipping. Specs: Intel Atom N270 1.6ghz CPU (Intel has returned to multi-threading) 10.2 inch screen 1GIG RAM 160Gig SATA II Hard drive Wired/Wireless NIC cards 3 Cell Lithium-Ion 2.64lbs No CDROM (not a big deal as I have a Lenovo USB CDROM drive anyway) The size: possibly the perfect size...small, light weight without being tiny. 10.2 inch 1024x600 screen and not an impossibly tiny keyboard (though obviously not full sized). It is about the size of a larger hard cover book. The OS: Comes with Windows XP and it ran very well...applications opened fast, web surfing was responsive and I could open several apps at once without much hit to performance. After 27 different questions about my loyalty to Bill Gates, I decided it was time to upgrade. Concerned that the new hardware may have issues with older versions of Linux, I jumped right into an as-yet-to-be released version of Ubuntu (9.04). Booted right up, answered a couple questions and installed like a champ...saw the disk, the RAM, the wireless card, everything...during the install. Upon reboot into Linux though, nothing...it just wouldn't boot. "No OS found". I thought my partitioning might be screwing me up, so I let the installer pick, but to no avail. I booted off live CD's, but when I mounted and chroot'd into my install, the install didn't even see my /dev/sda. At one point I finally got to a grub > boot, but still wouldn't boot to the OS. I tried a Debian 4.0 install, but that didn't see either the wired or wireless nics. Similar to the Ubuntu, Fedora 10 installed, but would never boot. So I tried a Ubuntu 8.10 install and everything was fine! Installed with my partitions (/boot, /, /home and swap) and all is well in the world. Wired, wireless, SATA, screen resolution....everything works straight from the install. I'm still testing and upgrading but over all this is a great netbook and takes to Ubuntu Linux straight away, and for less than $400 a great addition to my daily commute.

Re: [Wlug] Community Training

by Patrick Sawyer

We still kinda do this stuff. Unfortunately my time now gets spent on the job, not allowing much room for this stuff. I still get donations and we still give computers away, just not in the same capacity. I would be happy to go over the lessons I have learned, things that worked, and things we could have done better.

Yes, but it looks like there are also nice performance gains to be had when aligning partitions.

Re: [Wlug] Any ruby hackers?

by John Stoffel

Randy> I am learning Ruby right now. You can also ask your question on Randy> the bostonrb.org mailing list: Randy> http://groups.google.com/group/boston-rubygroup That's a great suggestion. I've been learning Ruby (on Rails) on an off for the past year or so, but this is my first real dive deep into the language and it's expectation. I'm not enjoying it really. :] Guess I'm too hardwired for Perl5. :] Thanks for the suggestions. Basically, I'm trying to extend 'philesight' to be able to recursively descend directories building it's DB of sizes, but with multiple kid or slave processes to spread the work out and have it complete faster. I actually had this working just fine with Ruby Threads, but then I found out that Ruby has a single thread for the interpretter, and jsut emulates real threads. So no performance gain. Now I'm working on forking() off kids to do the work, but the coordination is being painful. Anyone interested in what I've got? John
