Hi all We are currently considering using Slide for some project, and have done some preliminary analysis and tests on it. The only thing really stopping us is the surprisingly poor performance results we got during the tests. You can find the test report along with the source code to the test tool and domain files here: http://www.team-vision.com.mk/ivan/slide
Slide performance when dealing with objects of size 2-4 KB is on the order of 20 to 70 of kilobytes per second! The tests were done with MS SQL Server and Oracle as backends on a an idle 100 MBps LAN. There we're also some strange exceptions occuring, for instance Oracle's JDBC driver complained about having too many cursors open when the number of iterations was increased to 1000, and the JVM died with an OutOfMemoryError when the object size was increased (it was started with the -Xmx option specifying 512MB heap size), so there are concerns about serious resource leakage in Slide, especially after prolonged use. The tests were done on the Slide 1.0.16 release. The performance was so poor, that I'm doubting my testing tools and procedures, and whether I'm using the API right. I read every bit of documentation available, as well as the examples, and I believe what I have is the only way to fully create and read objects with Slide. The way I'm calling the Slide API is probably not the most optimal, but I think it's close to what a typical application using Slide would look like, which after all is what I'm trying to simulate... Please look at the report and/or the tool source code to see if I'm doing anything wrong. You're also welcome to try running the tool on any setup available to you, I'd be interested in comparisons with other platforms. If there is nothing seriously wrong with my way of measuring Slide, I'll probably do some detailed profiling next to see if I can identify any bottlenecks causing these results. Also, apologies if this has already been discussed to death on this list, I searched the archives and didn't find any detailed discussion specifically addressing any poor performance on part of Slide. All feedback is appreciated, thanks for your time. -- To unsubscribe, e-mail: <mailto:[EMAIL PROTECTED]> For additional commands, e-mail: <mailto:[EMAIL PROTECTED]>
