/work is mounted async, /usr is mounted sync:
; time cp -r rts10 ~alk
time cp -r rts10 ~alk
24r 0.0u 1.3s cp -r rts10 /usr/home/alk
; time cp -r ~alk/rts10 /work/tmp
time cp -r ~alk/rts10 /work/tmp
10r 0.0u 1.2s cp -r /usr/home/alk/rts10 /work/tmp
; time rm -rf ~alk/rts10
time rm -rf ~alk/rts10
11r 0.0u 0.3s rm -rf /usr/home/alk/rts10
; time rm -rf /work/tmp/rts10
time rm -rf /work/tmp/rts10
0r 0.0u 0.0s rm -rf /work/tmp/rts10
I suggest that those timing 'make world' might find it
interesting to compare times doing the build on an async mount.
