alkisg: it takes, I just measured it, a little under 6 seconds to start firefox on my laptop from 2011
09:49
but that's ssd, not hdd, of course

fiesh: yeah it's mostly about disk IO, hence my proposal to use local ssds/sticks whenever available
10:33
I managed to exactly pinpoint the nfs issue; it partly affects nbd/sshfs too; so expect nice speedups in the new ltsp :)
10:38
In numbers: booting ext4-over-nfs without the patch required 1160MB traffic, with the patch it requires 221MB traffic
10:38
That's a *big* speed up :)

Good stuff!

(it affects nbd/sshfs too, though to a lesser degree)
13:58
Aaaah, and that's also probably the reason NBD_SWAP sucks so much
14:01
By limiting readahead for all the other filesystems too (squashfs etc), traffic went from initial 1160 MB to 221 MB after NFS limit to 144 MB after all limits. Impressive!
