He just got a daughter [coming from Madagascar]. He is in Madagascar for the next 3 months with his wife, then 3-5 months taking care of her, he should be back part time in summer, full time in autumn.

I have made some benchmarks, looks like indexing time is more than twice longer. When there is a lot of circulation, the indexing of zebraqueue can take more than a minute. We know that this machine is not powerful regarding RAM and disk, but it was enough until now. Does anyone have the same problem ? The point is not to come back to obsolete GRS1, but is there a way to optimize DOM indexing ? My tests shows facets indexing does not change a lot. Did you try commenting the facets definition on the biblio-koha-indexdefs.xml file and recreating the biblio-zebra-indexdefs.xsl file? -- Paul Poulain, Associé-gérant / co-owner BibLibre, Services en logiciels libres pour les bibliothèques BibLibre, Open Source software and services for libraries
