I’ve just updated to Liquibase 2.0.2 from 1.9, and everything runs fine, but I’ve noticed two things:  
1.&nbsp; Everything runs a lot slower.&nbsp; What used to take 3-4 seconds now takes 15, even when there is nothing to update.  
2.&nbsp; I get the message 'Reading from `DATABASECHANGELOG`’ twice.  
  
I’m wondering if there is something I missed during installation (I simply dropped in the jar files and updated the schema), but since everything ran correctly, I’m a little confused.&nbsp; I’ve tried searching the forums, the documentation and even some plugins, but can’t find what may be causing this slow behavior.&nbsp; Is 2.0 simply slower than the old version was?&nbsp;   
  
Thanks

I haven’t done a performance&nbsp;comparison&nbsp;between 1.9 and 2.0 for a while, but from what I remember I wasn’t seeing that much of a difference. Reading from the databasechangelog table is done twice currently and could be&nbsp;optimized, but shouldn’t be taking 15 seconds. How many rows are in your databasechangelog table?

Slightly over 600.&nbsp; I just reverted to 1.9 and after doing a sync-update, the script takes 3 seconds.&nbsp; Glad to hear at least that the dbchangelog is read twice now, and it’s not just me.&nbsp;   
  
Where would I go about finding where to fix this issue?&nbsp; I tried installing the Logging/Log4J plugin, but ran into issues with it.  
Thanks for responding.
