i agree, ext4 is not the future like BTRFS. but ext4 is better than ext3. I don't know if the difference is felt in a fastbooting linux like moblin but on ubuntu 9.04 for exemple, without any optimisation there is like 10seconds better boot only switching from ext3 to ext4
by the way Arjan, you probably have an SSD drive i don't know if it has a jmricron based (or worse ? ) , what would be your recommandation for better performance and best lifetime ? ext3 ? ext2 ? reiserfs (who is known to be faster with small files) ? other ? ntfs ? (ok ok this one was a joke) of course a good solution would be to buy a GOOD SSD with at least 64MB cache (and SLC memory) but .... well they are not as cheap as the older generation with jmicron ... 2009/2/19 Arjan van de Ven <[email protected]>: > axel lin wrote: >> >> hi list, >> I found sreadahad (1.0) is independent of the file system type. >> And some report shows Ubuntu 9.04 have much improvement about bootup >> time ( compare to Ubuntu 8.10 ) and it is use ext4. >> I'd like to know to you have plan to use "sreadahead + ext4" for moblin2. > > we don't have plans to go to ext4; first of all it's still a very early > stage > in its maturity, and for us it just does not bring enough difference to > justify that. > Instead we are actively looking at BTRFS (and helping out with that); BTRFS > is looking like it will give a real performance and feature improvement over > the EXTx > series of file systems. > > Having said that, BTRFS is not ready today, so for Moblin 2.0 this is > obviously > not being considered. > > _______________________________________________ > Moblin dev Mailing List > [email protected] > > To manage or unsubscribe from this mailing list visit: > https://lists.moblin.org/mailman/listinfo/dev or your user account on > http://moblin.org once logged in. > > For more information on the Moblin Developer Mailing lists visit: > http://moblin.org/community/mailing-lists > _______________________________________________ Moblin dev Mailing List [email protected] To manage or unsubscribe from this mailing list visit: https://lists.moblin.org/mailman/listinfo/dev or your user account on http://moblin.org once logged in.
