I'm working on the initrd a but so tested a few things today. Once under linux, a cold-cache read of the initrd takes ~300ms, and the decompression about 1s. Changing the compression to '-1' (fastest) shaves maybe 200ms. OFW doesn't like non-gzipped initrds ;-) I'm tempted to say that reading/uncompressing the initrd is to blame only for about 1.3s -- probably 2s if we count cpio's work. This work is being carried out by OFW, which doesn't seem to be any slower -- following the messages on screen, the 'reading ramdisk' step doesn't take more than 2s. m -- [email protected] [email protected] -- School Server Architect - ask interesting questions - don't get distracted with shiny stuff - working code first - http://wiki.laptop.org/go/User:Martinlanghoff _______________________________________________ Devel mailing list [email protected] http://lists.laptop.org/listinfo/devel
