I've run again the benchmark with the current screened darcs, on the
same machine as before (which is a laptop, hence probably the slowdown
is accentuated by the slow hard drive), and on a new desktop machine.
Current screened contains these two patches, in particular:
http://bugs.darcs.net/patch1058 and http://bugs.darcs.net/patch1027 :
* (desktop) intel i5-3330, RAM 8 GB, hard drive buffered read speed
130 MB/sec, cached read speed 11300 MB/sec
(Total running time: about 5 minutes).
Without PI With PI
---------- ---------- -------
add 0.25 0.27
amend 14.08 17.74
obliterate 11.94 15.26
record 81.57 102.62
* (laptop) intel i3 U 380, RAM 2GB, hard drive buffered read speed 80
MB/sec, cached read speed 2100 MB/sec
(Total running time: about 30 minutes)
