Hi Marta, Presumably you are indexing polygons -- I suspect complex ones. There isn't too much that you can do about this right now other than index them in parallel. I see you are doing this in 2 threads; try 4, or maybe even 6. Also, ensure that maxDistErr is reflective of the smallest distance you need to distinguish between. It may help a little but not much. I can think of some internal code details that might be improved but that doesn't help you now.
There's some generic Solr things you can do to improve indexing performance too like increasing the indexing buffer size (100MB -> 200MB) and the mergeFactor (10->20 albeit temporarily and/or issue optimize), both in solrconfig.xml. Changing the servlet engine won't help. Calling server.addBean(item) isn't a problem either. ~ David Simonian, Marta M (US SSA) wrote > Hi, > > We are using Solr 4.4 to ingest geo data and it's really slow.
