I have a significant problem with the <lack of> speed of the OLPC. Even on NAND, if I (manually, in Terminal) copy a 5 MB file from one place to another, it takes seconds and seconds (as opposed to a desktop, where such a transfer happens in the blink of an eye). I have not tried any measurements, but my concern is that with an external device (*particularly* an SD card), access is even slower than with NAND. [And SD cards come in several speed ranges - the cheapest are usually the slowest). Empirically, I haven't noticed 'olpc-update' being significantly faster from an USB stick than over the internet. What raises my concern about treating an SD card as an extension of the Journal is - how fast will the XO be once there are a great many items for it to keep track of? I don't use 'suspend'; but the few times I've tried it - typically when attempting 'resume', my "Power" light stays on for more than three seconds, then goes back to blinking (in other words, the "un-suspend" times out). I suspect some of those seconds are being spent accessing the 100 or so files on my SD card. [Would be nice if the OLPC had a 'Storage Device Busy' light for me to look at.] What will be the performance of the OLPC (including: how long will it take to boot?) when I have several thousand files on my SD card? mikus _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
