Subject Re: Initial Performance Measurements of Geronimo Using DayTrader - Bottom Line ... we're gonna mix it up :)
Date Sat, 08 Oct 2005 03:51:42 GMT

Thanks for this.  I think that we have nothing to be ashamed of here  
- M5 is our first fully certified release, and now that we're "in the  
club", we can start really focusing on usability and performance.   
Given that we never focused on performance before, I'm sure there is  
a ton of low-hanging fruit to go after, and we'll see progress in  
leaps and bounds.


(geeze, we even have geronimo slide presentations now!)
