I'm doing some performance testing against an 8-node Solr cloud cluster, and I'm noticing some periodic slowness.
http://farm4.staticflickr.com/3668/10985410633_23e26c7681_o.png I'm doing random test searches against an Alias Collection made up of four smaller (monthly) collections. Like this: MasterCollection |- Collection201308 |- Collection201309 |- Collection201310 |- Collection201311 The last collection is constantly updated. New documents are being added at the rate of about 3 documents per second. I believe the slowness may due be to NRT, but I'm not sure. How should I investigate this? If the slowness is related to NRT, how can I alleviate the issue without disabling NRT? Thanks Much! -Dave
