Performance question here : my Galaxy Nexus is really slow right after I connect it to a WiFi network after long periods not being connected to the internet. That doesn't happen on EDGE or on 4G, and after a while it goes back to normal.
My first guess for the culprit is : the low latency of WiFi networks, combined with the (potentially large) number of apps waiting for a connection to wake up, can spawn a lot of threads, which get data almost immediately, and start processing it right away, all at the same time (unlike EDGE where data can take a while to download). Which obviously clog the CPU and RAM. Is there an app or conmand-line tool (phone is rooted and running CyanogenMod 10, btw) that can show me which ones are doing too much work?
Off-Topic: As a developer, do you know of any tricks that can minimize that effect when syncing in background? Other than not doing it when unnecessary, of course!
