--- Comment #5 from Jonathan Druart <jonathan.druart at bugs.koha-community.org> ---
Quick benchmarks:

% more /dev/null > /tmp/time;
% export KOHA_INTRANET_URL=http://pro.koha-qa.vm
% for i in {1..10}; do {time perl test.t > /dev/null} 2>> /tmp/time;done;
echo $((`perl -pe 's/.*cpu ([^s]*) total/$1/' /tmp/time| tr '\n' '+'|sed
's/+$//'`))

# Before 16044
git reset --hard ffb17a2914c43e536155856a86fed374b7f26e9c # just before 16044
71.23 (7.389+6.932+6.966+6.937+6.941+6.663+7.827+7.237+7.075+7.259)

# After 16044
git reset --hard origin/master # + last patch on 16044

# With 16140
git bz apply 16140
63.60 (6.952+7.158+6.481+6.424+6.428+6.338+6.003+6.034+6.004+5.782)

# With 16088
git reset --hard origin/master # + last patch on 16044
git bz apply 16088
73.43 (9.092+7.246+7.020+7.053+6.859+7.081+7.045+6.932+7.068+8.037)

# With 16140 and 16088
git bz apply 16140
61.21 (7.403+6.036+6.127+5.881+5.674+5.971+5.779+5.901+5.643+6.794)

The standard deviation is very high and it seems that my laptop is not stable
enough to get correct values. Could someone confirm/contradict them?
