I spoke too soon! Wereas three days ago when the index was new 500 records could be written to it in <3 seconds, now that operation is taking a minute and a half, sometimes longer. I ran optimize() but that did not help the writes. What can I do to improve the write performance?
Even opening the Logging tab of the Solr instance is taking quite a long time. In fact, I just left it for 20 minutes and it still hasn't come back with anything. I do have an SSH window open on the server hosting Solr and it doesn't look overloaded at all: $ date && du -sh data/ && uptime && free -m Fri Oct 26 13:15:59 UTC 2012 578M data/ 13:15:59 up 4 days, 17:59, 1 user, load average: 0.06, 0.12, 0.22 total used free shared buffers cached Mem: 14980 3237 11743 0 284 2222 -/+ buffers/cache: 729 14250 Swap: 0 0 0 -- Dotan Cohen http://gibberish.co.il http://what-is-what.com
