The recorded webinar for “Prove it: Can ERDAS Really Deliver Terabytes of Imagery Faster than the Competition?” has been posted to the ERDAS Website at the following URL:
This download contains the webinar recording. The PowerPoint presentation used during the presentation and the LoadRunner Performance Report generated during the presentation that reports on the Servers usage and throughput during the load test will be posted tomorrow.
This webinar demonstrates LIVE an ERDAS APOLLO with a load test running 500 concurrent users on it then live use of a web client using this server (simulates being the 501’st user). It also demonstrates several publicly available web sites that showcase our technology in publicly available web sites.
I had to cut short the questions at the end of the recording and we fielded another 20 minutes of questions that were not recorded (I wanted the recording to be 60 minutes and it ended up 75 because of questions).
I'm going to reproduce the demonstration with 1000 users next time, try and put a heavier load on the server. 37% resource usage is nothing!
Chris Tweedie of our ERDAS Australia Region has recently reproduced the FOSS4G raster imagery performance benchmark tests using ERDAS APOLLO to compare the results and has published them on his blog:
We've all been really busy with the Recent APOLLO 2010 Release, but Chris made it a priority to get these numbers completed and published. Nice work Chris!
Chris did a great job of providing graphs for Image Format performance for each Map Server and graphs for Throughput and Response Times for each format with each Map Server to make it comparable by Server or by Format/Server.
Some analysis of the results:
1. ECW imagery format is a "performance purpose" built imagery format. The throughput of ERDAS APOLLO with the ECW format is 2.5 the Open Source Servers at a 150 user load and can support a much higher load than 150 which wasn't represented in the this test scenario. The throughput curve had a steep positive slope even at 150 users where the other servers were peaked out with throughput at the 150 user measurement.
2. ERDAS APOLLO outperformed each Open Source server on every image format with the highest Throughput (transactions/second) and lowest Average Response Times (the time that it takes to get the image on your map). ERDAS APOLLO outperformed open source with every image format in the test.
ERDAS will be providing several webinars and whitepapers regarding the subject of "Raster Imagery Performance" to showcase the ERDAS APOLLO 2010 and it's performance capabilities.
Keep in mind that these numbers do not even showcase our faster imagery protocols that we provide with ERDAS APOLLO....
ECWP and our Optimized Tile Delivery are MUCH faster and support much higher user loads compared to the WMS protocol (THOUSANDS of users on a standard server). In short, we can produce maps MUCH FASTER than these numbers published with the "slowest" protocol provided by the APOLLO 2010.
