Been there...so much for AI...

Yep, even with a registry cleaner, I'd have to blame the interweb...comcast used to be the quickest but now, not much better than the rest.
At work, it's like the days of: "You Have Mail"...log on, go eat supper, come back, punch in an isp and go have desert, come back and MAYBE...you'll get to where you wanted to go...

So far the only slowness I have noticed is on my ipad. It’s taking three to five times longer to boot up from a cold start. Annoying. Not doing any of the cloud stuff -ever , but who actually knows what these contraptions are really programmed to do.

my apologies, typing on my cell phone leads to auto-correct words I wouldn't have used.

I just got on line today...been trying for three days. But I notice it is running really slow. I actually could not get on line at all previously. The whole world must be on line.

At work i'm responsive for no less that 75 pcs, 15 mac's, and a dozen servers. I've seen slowness. There is has been a steetp uptick in hack and malware attempts identified by my firewalls and my Anti virus platform. The trouble is the internet, more people are using it than ever and companies are scanning everything they can to try tot weed out undesirables in social media. This enhanced scrutiny by the major players takes processor cycles and memory away from systems which route things across the web which causes things to slow down, sometimes to a crawl.
The slowness I see across my systems is with updating and prefetching and not so much at the workstation level. Still when a server is bogged down those requesting info from it receive delayed retrieval times. Fortunately were generally running 10g across the backbone and 1g to each desktop, but I notice the extra weight in my management tools

I've been noticing a lot of that lately. I've opened diagnostic tools to try and figure out what is going on, but haven't had success. I have Apples and I've said if Jobs was still alive he'd be rolling heads over this!

The odd thing is, I can't identify anything eating up CPU time or Network time, yet the system acts like it's struggling for resources it can't get.

Side note: On my MacBook Pro I've caught several versions of something from Google trying to do "updates" without my permission when I don't use anything Google. After force quitting that crap, things seem to run a little better. I don't have that problem on my iMac desktop. I'm working on it.
