All internet-based apps suddenly slow; fan speed high

JimmyCMPIT,

(1) Thanks for responding.

(2) I reset the SMC

(3) I booted into safe mode

(4) I rebooted normally

The behavior continues. Worse,...

(5) Now some websites are not either (a) not loading or (b) not loading correctly (e.g., webages load raw-text without images, styling, etc.).

I'm not familiar with etrecheck.com. It is loading now. It might be awhile until it loads and I can do something with the website.

I also just tried all the data/cache clearing recommended by Linc Davis here: Re: Safari Web Content not responding - Yosemite.

The behavior continues.

More detail:

- ping times are all over 400ms.

- (I will post a few dozen lines of log when I use another web-based app)

Here are the logs from around the last time I tried to load a webpage in Safari.

It was around 11:24:40 (plus or minus a bit). The webpage took a long time to connect (almost 100 seconds) and the fan kicked on.

Logs:

One more log from another instance of the behavior (aside: discussions.apple.com is displaying a minimal non-styled text in Safari as I write this):

(I'll stop posting logs until I hear more instructions)

I've decided to reinstall the OS (without restoring any users or settings from a Time Machine backup) — using this method (more or less): http://www.thesafemac.com/how-to-reinstall-mac-os-x-from-scratch/

I've been rebuilding things from scratch since yesterday evening.

Everything works again (so far).

Thanks for those who tried to help.

I'm now having this problem on a *second* machine. I've resintalled and migrated everything but settings, but it's still an issue.

How can I locate the problem in the user to fix it? I don't have time for another fresh install like last time.
