Subject Re: [jira] Commented: (DERBY-1664) Derby startup time is too slow
Date Thu, 10 Aug 2006 18:23:44 GMT
I recognize this bug is too vague, but I wanted to get something into 
the system so we can start investigating it.  If I knew what "fast 
enough" was, then perhaps we could have a measure to close it.

If you were to ask me, "fast enough" is no more than 3 seconds with the 
default configuration.  5 seconds is pushing it.  What do others think?

 From a user's perspective it's irrelevant what component is causing the 
delay, it just takes too long (e.g. when I run 'connect 
jdbc:derby:mydb;create=true').

Also you of course need to describe the hardware configuration.  It all 
gets so nitpicky, when what we're after is fixing a perception.  Maybe 
it can be created as a project on the Wiki with a series of JIRAs 
attached to it?

this affects overall perception of Derby.  This appears to be related to another common complaint
that it takes too long to create tables.  I am marking this as Urgent because of the impact
it has to Derby perception and the fact that the 10.2 release is going to get such wide distribution
through the Sun JDK.
