I've noticed that solr is using only one of my four CPUs for applying the update. With that in mind, could I submit my batches in parallel, or would that be worse? To be honest, I've never seen what kind of transaction or coherency model is used in solr. I think it's touched briefly by the solr-ref-guide for applying updates to single document fields; but I can't say for sure if it's using an optimistic strategy or if the parallel updates would produce more overhead by pessimistic locking. regards, =1
