Does Solr use some sort of a persistent cache? I do this 10 times in a loop: * start solr * create a core * execute warmup query * execute query with sort fields * stop solr
Executing the query with sort fields takes 5-20 times longer the first iteration than the other 9 iterations. For instance I have a query 'hockey' with one date sort field. That takes 768 ms in the first iteration of the loop. The next 9 iterations the query takes 52 ms. The solr and jetty server really stops in each iteration so the RAM must be emptied. So the only way I can think of why this happens is because there is some persistent cache that survives the solr restarts. Is this the case? Or why could this be? /Tim
