Performance improvement #35

Open chrissy25 opened 8 years ago

chrissy25 commented 8 years ago

Hi,

for Chrome and Firefox the library is working fine, but for IE I have some performace problems, especially during the initial load of the map, this takes very long and the IE will freeze for some time.

I would like to know what does the library do in the initial load? What is the most time consuming operation? I would like to have a look into the code to check if it could be improved, but wanted to cross check first, if you already know what the most time consuming parts are :)

There is a way to generate the map traversal in advance and cache that which speeds up the load process greatly. We haven't documented that part well yet, but are using it in production.

Could you describe me how to use it or give me a hint on this? We would like to use it for relativly big maps and the browser which is used most is the Internet Explorer for us ... so we need to improve the performance a little bit^^

The https://github.com/ucdavis/wayfinding/blob/master/tasks/datastores.js file can be used to pre parse the maps, and in the test folder there are examples of this in use https://github.com/ucdavis/wayfinding/blob/master/test/datastore-test.js
