How to assess player computer speed?

[Karlovsky120]

I'm creating a chunk pre-generator and I'm running into trouble with "Already decorating" exception. I figured it was because I was calling the methods to populate and generate chunks too fast. To fix it, I put a delay before each call (about 250ms works for me). However, I don't want players having to decide how fast they would allow for terrain to generate.

 

So my solution to this would be to have somkind of a fast benchmark which would be ran everytime before I try to generate, to see what their computers are capable of, and that use that info to set the appropriate delay. But I have no idea what method I could use or call that wouldn't really affect anything, and would be intensive enough to have a somewhat reliable results.

 

On a related note, whenever I generate a chunk, I immediatley save it, drop it, and unload it (unloadQueuedChunks()) . Could it be im getting the error because I'm (in theory) having no adjacent chunks loaded? I know  Minecraft loads chunks when decorating cross-chunks, but I'm just no that familiar with the mechanic.

 

Help please?
