With the Jira 8 release, Atlassian worked on performance optimizations and internal changes, in particular on the search and indexing engine Lucene.
In the release notes, Atlassian gives the following metrics:
Our tests are done on a Jira Software instance:
|Items||Amount of data|
The indexing engine used in Jira is Lucene and it has been updated from version 3.3 to 7.3. This is a huge change since the 3.3 version was from 2011 ! With such a jump in time, we can expect a significant performance improvement. Does it hold up to our tests ? We had 3 use cases :
The results confirm Jira 8 speed :
|Action||Jira 7||Jira 8||Gain||Atlassian estimate|
|Locked reindex||2 994 s||1 883 s||37%||71%|
|Background reindex||1 862 s||619 s||66%||71%|
|JQL search||6,1 s||4,4 s||28%||31%|
The Kanban and Scrum boards are up to 71% faster on Jira 8 according to Atlassian. Our test was done with a board having 61 762 issues :
|Iteam||Jira 7||Jira 8||Gain||Atlassian estimate|
|Kanban board||12,48 s||6,87 s||45%||50%|
|Backlog||11,69 s||6,47 s||44,5%||50%|
These tests show that Atlassian actually worked a lot on improving Jira 8 performances since a reindex is 30% to 60% faster with files 50% smaller too, and a board is displayed 45% faster than with Jira 7 ! We found overall the same performance gain in our testing than in Atlassian announcements.
The new version of Atlassian project management tool gives both administrators and users an improved experience in their daily use of Jira.
