[jira] [Updated] (SOLR-6820) The sync on the VersionInfo bucket in DistributedUpdateProcesser#addDocument appears to be a large bottleneck when using replication.

     [ https://issues.apache.org/jira/browse/SOLR-6820?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Timothy Potter updated SOLR-6820:
---------------------------------
    Attachment: SOLR-6820.patch

First pass ... raising this to 65536 as Mark indicated made a significant impact in overall indexing performance in my testing. 

Specifically, with branch_5x my baseline got:
{code}
num docs         secs         docs/sec
9992262          427	      23401.08 (no replication, leader only)
9992262          758	      13182.40 (leader + 1 replica)
{code}

with this patch applied and using 65536:

{code}
9992262          382          26157.75
9992262          710          14073.61
{code}

that's a pretty significant bump in overall performance for an additional 0.5M of memory per collection IMO
