How to track down the source of Internet ‘crawl’ on a MacBook?
Is there a way to figure out whether Internet slowdowns are caused by ISP inefficiencies -or- by lack of free memory and/or high CPU usage?
I experience extended periods of slow-to-very slow Internet access on a daily basis and would like to find out what’s causing these.
Symptoms:
• Slow (as well as momentarily frozen) webpage loads
• Delayed appearance of typed text
• Non-response to mouseclicks or mouse/keyboard navigation commands
• Spinning beachballs
• Extended fan usage
All are very common. A day doesn't go by without some or all of them occurring.
Re: memory usage, with only the browser running, it rarely takes very long (usually under an hour from power on) for Activity Monitor to show little-to-no ‘free’ memory and high levels of ‘active’ (over 50%) and ‘inactive’ (around 25%) memory.
I do tend to have a lot of tabs open, but (as far as I'm aware) the better part of 2 GB is a lot of memory for a 'browser' to use up all by itself.
What's the solution?
Thanks.
