Why is it so slow?

I have 3ghz, 6g ram, right out of the box, and the HD video clips in PE8 are skipping and slow. When it's not playing video it's also mad slow.
The regular windows video editor has no problem playing HD.
Any way to speed this up?
thanks

Welcome to the forum.
First, please tell us all about the source media files, and then please give us more info on your system, especially the I/O sub-system, i.e. your HDD's, their speed, size, controller type, free space and how they are allocated.
With all but AVCHD material, the I/O is the most important aspect. With AVCHD, the CPU is the more important factor in the equation.
To get the most out of your system, the tips in this ARTICLE might prove useful.
Good luck,

Why does Photoshop keep slowing down?

I've been using Adobe Photoshop CS5.1 for two years now, and for some reason it seems to have the problem of slowing down after using it for a while, so if I'm working on a project I have to keep closing it and reopening it to get it fast again. It's weird because it doesn't seem to matter how much stuff is on the canvas, it's just how much I've drawn and hit undo and erased or did anything, After like 5 minutes of straight work it just gets too slow for me to work in, like when I switch tools or change the color it takes a couple seconds to respond. So literally every couple minutes I have to restart Photoshop and open the same file.
What's really odd is that sometimes Photoshop will work perfectly fine and stay lightning fast for hours. Like, for the last couple of months it's been 100% fine, but since a few days ago it started to have this "slowing down" issue again. Every couple months it seems to decide to be perfectly fine or just really annoying. I didn't change anything in my computer.
It can't be my computers specs or my settings in Photoshop, but I will tell you all of that anyway.
OS - Windows 7 64-bit
CPU - Intel Core 2 Quad Q6600 @ 3.0GHz
RAM - 12GB DDR3 @ 1333MHz

There is no malware scanner running, in fact I have tried closing out all other applications and unnecessary processes to help improve performance. No luck.
Also, my post actually wasn't quite finished, but my internet shut off on me last night and I guess that just automatically posted whatever I had done before then. What's even better is that the forums won't allow me to edit it. What great features!
Anyway, here's the FULL spec sheet of my computer...
OS - Windows 7 64-bit
CPU - Intel Core 2 Quad Q6600 @ 3.0GHz
RAM - 12GB DDR3 @ 1333MHz
GPU - NVIDIA GeForce GTS 450 1GB
Storage - 1x 128GB SSD (OS installed on), 1x 750GB HDD, 1x 160GB HDD
I have the 64-bit version of Photoshop CS5.1 Extended, installed on the SSD. Here's the settings I have in the preferences:
Memory Usage - 100%
Scratch Disks - All 3, SSD 1st, 750GB HDD 2nd, 160GB HDD 3rd
History States - 100
Cache Levels - 8
Cache Tile Size - 1028K
I have fiddled with these settings and restarted Photoshop countless times. In the end it's the same exact result: Photoshop slows down after a few minutes of work and I have to restart it. I have about 50GB free on the SSD, 150GB free on the 750GB, and about 140GB free on the 160GB.
I don't understand why it gets so slow even when my RAM usage only makes it up to about 45%. Why doesn't it just utilize ALL of the memory like I told it to?
I've tried setting cache to 1, 2, and 4, same result. Cache tile size to all the different settings, same result. History states to an extremely low level like 10, same result. I just don't understand why Photoshop is doing this, especially because it decides to speed up on its own every couple of months...

Why is Start up slow on MacBook Pro after Lion installation?

I've noticed that it takes a while for my MacBook to turn on and start-up since I installed Lion. Any ideas why or how to correct? Thanks!!

Your machine is likely too dated to run 10.8 adequately.
Apple makes it easy, doesn't mean it's right match for your hardware.

Why Portal will be slow when we work on Theme Editor

Hi Experts,
Why Portal will be slow when we work on Theme Editor in Creating new Theme or modifying existing one.
Note: Since i have done Branding for 6 to 7 Clients i fell same , portal runs very slow.
Thanks
Vijai

Hi,
use the Eclipse Theme Editor. No need to be logged on in the portal, hence: faster. You'll only have to upload the theme afterwards to the portal.

Why is internett so slow with Airport express???

Hi!
I have a mac mini and a pc.
I sometimes think that my mac mini is so slow when I use Internett.
There is a norwegian page that I have tested it on... and the answere was alarmin:
My pc had a connection of: about 4000 kbit/s connected to wireless and airport express... and about 6000 with out wireless.... hmmmm I tested it many times...
My mac mini (which is in my livingroom) had a connection at only 919 kbit/s????
why is it sooooooo slow???? can I do anything to speed it up????

Great Henry,
That was great advice, I have been unofficially been working in WiFi for my school and this is one of the most clear responces I've seen from discussions. Anyways some things that I do believe that you forgot was cordless phones 2.4Ghz range, microwave ovens, DSS (Direct Satellite Service), Electrical things like power lines, Other airport/WiFi stations, and moving objects made of metal between the computer and base station. Those are all broad things. Usually things like that won't effect it but it really depends. For the cordless phone you just need to change the channel on the airport. I hope that helps, Good Luck!
Jon
PS I have found that sometimes its just plain wackey, usually cause of wires and such things in the walls

Why is facebook so slow on my Iphone with IOS 8?

Why is facebook so slow on my Iphone with IOS8?

Here is the article explaining why.
Developer Steve Streza, iOS devices are programmed to ping a test URL upon connecting to a Wi-Fi network to see if it’s protected by a “captive portal.” And that test page has been down all afternoon…
Here’s more on that from Errata Security:
“When an Apple iOS device (iPhone, iPad, iPod) connects to a WiFi network, the first thing it does is make a request to the URL http://www.apple.com/library/test/success.html.
The purpose of this request is to discover if there is a “captive portal” in the way. A captive portal is when, after connecting to the WiFi, any web request you makes gets redirected to a login/ToS page. In order to continue, you must either login with a username/password (or sign up, then login), and/or access the Terms of Service.”
Anyway, it sounds like Apple was able to correct this issue on their end, so no update will be necessary. But if you’re still having Wi-Fi problems, you can try the following:
Toggle your Wi-Fi off and on – Settings app > Wi-Fi OR
Set your device’s HTTP Proxy to Auto – Settings app > Wi-Fi > Blue icon next to the network you’re connecting to > Scroll to the bottom
One of these methods should cure your iOS 6 Wi-Fi troubles. If not, be sure to let us know in the comments below.

Why does Lion seem slower than Snow Leppard?

It's anyone's guess. Startup and shutdown as well as application launches take longer in Lion than they did in Snow Leopard on the three Macs that I "upgraded," and I also see the spinning beach ball more often than I used to. Add to that the HDMI-related crashes on my Mac mini...
Quite frankly, I have yet to see where I have gained any advantages after upgrading to Lion, and I definititely have problems that I didn't have under Snow Leopard. Of course, all of it must be my fault, as Apple would never ever relase an upgrade that was less than perfect.

There can be several reasons:
You have a slow Internet connection
You Tube is experiencing connection slowness
Anywhere in the route between you and You Tube is experiencing slowness
I'd start troubleshooting with the Internet connection. What upload speed are you paying for? What upload speed are you getting?

Send Apple feedback. They won't answer, but at least will know there is a problem. If enough people send feedback, it may get the problem solved sooner.
