question about an entry in the log file

[kaveh minooie]

Hi eveyone

I am trying to figure out why calling commit from my client takes a very 
long time in an environment with concurrent updates, and I see the 
following snippet in the solr log files when client calls for commit. my 
question is regarding the third info. what is it opening? and how can 
make solr to stop doing that?


INFO  - 2017-09-19 16:42:20.557; [c:dosweb2016 s:shard2 r:core_node5 
x:dosweb2016] org.apache.solr.update.DirectUpdateHandler2; start 
commit{,optimize=false,openSearcher=false,waitSearcher=true,expungeDeletes=false,softCommit=false,prepareCommit=false}
