[jira] [Commented] (JCR-3137) Slow repository startup

["Jukka Zitting (Commented) (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/JCR-3137?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13143484#comment-13143484 ] 

Jukka Zitting commented on JCR-3137:
------------------------------------

Here's some rough measurements over recent releases (time between "Starting repository" and "Repository started" messages from RepositoryImpl, plus the total repository size after the default install):

    1.6.5: install 19s, restart 2s, size 4.0MB
    2.0.5: install 20s, restart 3s, size 4.2MB
    2.1.6: install 21s, restart 4s, size 4.2MB
    2.2.9: install 29s, restart 3s, size 6.2MB
    2.3.2: install 29s, restart 4s, size 6.3MB

Not sure what's taking up so much time in the initial install, perhaps it's the time taken by Derby to create the initial databases. Perhaps H2 would be faster?

> On my reasonably fast computer I'm seeing over 30 seconds to start up a new repository from scratch. The startup is much faster if the repository already exists, so this has something to do with the initial setup. Ideally a new empty repository should come up in no more than a few seconds.
