The results are quoted right above, literally above. Raise your eyes up. message-id 0927bcab-7e2c-c6f9-d16a-315ac436ba98@virtuozzo.com
I write it here again:
with the patch:
best: 9.7G reclaimed
worst: 16G reclaimed
without:
best: 35G reclaimed
worst: 136G reclaimed
Or you asking about something else? If so, I don't understand what you want.
