Hi, For testing purposes I've been replicating a database (doc_count:24712508, doc_del_count: 769920, update_seq: 135828514) to another Couch instance built from the current 1.2.x branch (pull replication using replicator db, if that's relevant). Both databases are running on virtual machines with similar setups.
However the indexing of the views on the 1.2 couch are considerably slower (maybe 1/10 of the speed) than on the other server. As far as I can tell, its not the hardware that's causing the low performance, because the VM's CPU is hardly active (~20% CPU by beam.smp, maybe ~1% for couchjs, nothing else active) and disk performance seems OK based on some tests. I've already applied some of the performance tips from http://wiki.apache.org/couchdb/Performance but that didn't bring any improvement. Do you have any tips how to analyze performance bottlenecks, or any suggestions on how to improve performance? Thanks! -- Stefan
