More results from the load testing. Previously I had just been testing with a server which only had 5 users registered on the LD system and 2 Units of Learning, and I was only load testing with 3 concurrent users. This morning I added more users and UoLs, so we had 20 users registered and 10 UoLs. I then tried the load testing but still with only 3 concurrent users.
For the first set of testing (with 5 users registered) we had average response times of 11-12 secs for Sled player and 2-3 secs for CopperCore player. Though as I mentioned earlier – it;s difficult to compare these two directly as they are measuring different things – I’m really looking at the relative differences, not the absolute figures. Then when I tested with 20 users registered on the server (ecah assigned to 10 UoLs) the speed decreased quite dramatically to 30-35 secs average for Sled and 9-10 secs for CopperCore – so both players were about 3 times slower with a very small increase in the number of users registered.
For info, I was doing this testing on an old laptop (about 4 years old – PII, 200MB ram) and with a default installation of CopperCore and Sled. I also restarted the CopperCore service before the start of each test.
We’ve also found another little problem that is affecting the player, and that is that if someone double clicks a link in the activity tree menu (so clicking again before the server has had chance to return anything after the first click) this is generating a blank page (just the Sled header and footer) – so I’ll need to see what is causing this problem!
