I was starting to perform some tests on the beta grid with Mono. My current interests are with encryption. Encryption can slow down the execution speed of a script if it is very strong. I am considering using the XTEA encryption algorithm for my current development efforts. It starts running into degredation problems depending on the stregnth of encryption, or the amount of data being encrypted.
I ran over to the beta grid to run some tests against my implementation. Through regular LSL script execution, I was seeing it take roughly 48 seconds to execute. I compiled the script for Mono and saw immediate results running at 2.5 seconds. That’s around 20 times the speed of old- school LSL!
Inflated Results
But wait – something was odd. Over on the main grid, it took 21 seconds to execute LSL. This really has me scratching my head. Has their been a slow- down of LSL on the preview grid to inflate the performance increase that Mono offers? I notice that the mono information keeps referring to LSL2. Perhaps LSL is running slower on the beta grids because they are running 2 virtual machines (Mono and LSL). I ran to another sim and found that the LSL script ran in 57 seconds (even slower!).
Script Latency
Another possability could be that there is a lot of script latency. Not quite! On the main grid in Woodbridge, I had 3378 active scripts running with about 36,000 IPS. A regular sim on the preview had only 1 acitive script (mine) and about 7,000 IPS. A mono sim had 371 active scripts and 0 ips. Well, I suppose ips only counts for LSL scripts. Perhaps this “LSL2″ virtual machine doesn’t broadcast itterations to the region. Perhaps mono can not even record IPS.
I suppose the next question is, when will Mono make it to the main grid? According to the Mono page on the Second Life Wiki, we shoudl see Mono deployed … yesterday!
