Today I noticed that I have (what seems to be to me) a lot of data being sent/received even when I have very few applications open and am not doing anything strenuous. By that I mean when I just have iTunes, Chrome (only 2-3 tabs), TextEdit, and Finder running.
Right now I seem to be peaking at around 3-5kb/sec when idling, and apparently have received 5.16 GB of data and sent 257.7 MB. I do watch a lot of Youtube and browse Tumblr (and often upload gifs to Tumblr), but I don't know that that fully accounts for it. What on earth could need me to send all that data?
When I'm browsing Tumblr, data sent/received can peak even higher, once peaking over 600 kb/sec! Once, while on Tumbr, I saw it peak to 100+ packets/sec, with more packets being sent than received.
Activity Monitor indicates that I'm even occasionally sending/receiving data (382 bytes each) for a few moments after my Wi-Fi is turned off.
Can anyone give me any info on normal network activity and/or tell me whether or not what I'm experiencing falls within expected network activity? Could there be something nefarious going on?
