We have faced a similar issue about zebra facet performance, but we have
identified another variables that affect the zebra performance
We were working with koha 16.05.05 debian 8 plack enabled, 4 cpu , 8 RAM + 100
GB on SSD.
>From fresh install, load a database of 225.000 bib records + 300.000 authority
+ 260.000 item record.
When searching we found that stopwords increase the time response up to 12
times...
Koha Search: Felipe Rey España (15 secons)
Koha Search: Felipe Rey de España (110 seconds)
If we turn on queryfuzz and query stemming the speed increase sharply
Koha Search: Felipe Rey España (5 secons)
Koha Search: Felipe Rey de España (20 seconds)
If we turn on zebra facets, it becomes very fast
Koha Search: Felipe Rey España (1,5 secons)
Koha Search: Felipe Rey de España (2,5 seconds)
If we turn off zebra facet and keep query steemming and qeryfuzzy on it has the
same performance behaviour that turning off facets
Koha Search: Felipe Rey España (5 secons)
Koha Search: Felipe Rey de España (20 seconds)
then here we have a mix of issues with stopwords, querystemming, queryfuzzy and
zebra facets.
Hope it helps
