Hi Shawn,Thanks for your response. I have several Solr cores on the same
Solr instance. The particular core with slow retrieve response has 6 gb
data. Sorry for the confusion.I restart Solr and ran same query with rows=0
vs 10000, QTime for both are OK, so I guess it is the retrieving slow? I
also tried return different rows, the more rows, the longer retrieving time.
The machine has 64G ram, I tried 32G for Solr Heap memory, but the
performance didn't improve much. Any suggestions? Thank you very
much!=============================Return 0 rows:232 --.-KB/s in 0s {
