Did some research ... turns out flash disks dont last ... (limited writes) .... the leveling algo distributes the writes among a large group of mem cells. I found out using hdparm -i that the timed reads were significantly faster on the hdd compared with the hdd ... Maybe the spin delay might be eliminated in case of flash. Solution slax toram http://www.slax.org/ How about using tmpfs or ramfs ... to create a fast access folder. improvement possible during compiles ... copy the files to a ramfs/shmfs dir and do the build there. i've made a little incomplete script ... see attach [S,s]teven -- Life would have been a lot more easier if we could look at the source code.
