Does auto statistic slow down inserts?

I found some code on the web to loop through my table's columns dropping indexes so I could do fast inserts overnight. The table has five million records.
The loop threw an error on one of the indexes:
"Cannot drop the index 'ACCOUNTS._WA_Sys_0000000F_31EC6D26', because it does not exist or you do not have permission."
which I gather is an auto-statistics index. Do I need to find a way to drop this index? Currently my INSERTs are still not terribly fast (even though all the indexes showing in the Indexes window have been dropped).

The hypothetical column has zero per this query
select * from sys.indexes AS i
left JOIN sys.index_columns AS ic on ic.object_id = i.object_id
where i.object_id = object_id('Accounts')
object_id
name
index_id
type
type_desc
is_unique
data_space_id
ignore_dup_key
is_primary_key
is_unique_constraint

The id 837578022 is the same ID showing in the original query so I'm pretty sure it's the same index at issue.
As long as it's not having a significant impact on my INSERTs, I have no quarrel with it. I guess I'll just presume the best, for now.

Hi. I am going to be buying a macbook air 2012 soon with 4 GB of RAM and wondering how much memory space does norton AV take up and does it drastically slow down the mac. Thanks a lot :)

Hi
I am going to be buying a macbook air 2012 model with 4 GB ram soon. I was wondering how much space (memory) does Norton AV take up and does it drastically slow down the computer. Also, I am going off to uni so will predominantly be using the laptop for surfing and MS office.
Thanks a lot

Sorry to disagree mende1. In this age of email attachments and social networks, it is actually a good idea to have a good antivirus on your system. {I realize that this is a religious argument and I will say no more}. With that said, the general concensus is that Norton AV is terrible. It is intrusive and uses up a lot of cycles.
There are a lot of better AV clients out there. I use ClamXav which is free and uses the clamav antivirus that is open source.

Why does project save slow down over duration of project life?

I notice when I'm editing in a project in Premiere Pro CC, the auto save or even if I just save, the save slows down over time. You can slowly see the save bar going slower and slower over time. Even if I don't add any new media or import different files the save still goes a lot slower overtime. Sometimes the save bar will hang at a certain point for 20 secs or so and then continue. I understand if I add more media, files, pics, music etc... the save will take longer. But why does it do this if I'm just editing with some effects? Is it something to do with the cache folder getting too large or that I have too many auto saves? Should I clean out these folders? Also if it hangs at one spot for 10 secs or so is it because there is a corrupt file somewhere?
I just find this very frustrating if you are saving every 5 mins and you have to wait for 30 secs for a save.
My specs: Mac Pro 2009
Processor 2 x 2.26 GHz Quad-Core Intel Xeon
Memory 32 GB 1066 MHz DDR3 ECC
Graphics NVIDIA GeForce GTX 680 2048 MB
Startup disk SSD

I can answer some parts:
The auto save works as a five project silo. Once the list gets to 5 saves, it starts to write over. Also the auto-save only saves the project--no assets, no renders, thus the file is relatively small.
applying aneffect (filters transitions, etc) causes the program to create a new file as Premiere does not modfy the original asset. The more effects that are used, the more files that are created. When you finally export, the AME creates a single file, once again, not affecting the original assets.

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...

Copy and paste, does the process slow down if...?

What is the optimal way to copy and paste multiple tasks?
My question is: Does the copy/paste slow down if I have multiple copy/paste processes at the same time?
Or, should I wait until each is done to continue the next task?
I have about 3 hard drives I'm trying to copy and paste to and from each other. Each transfer can range between 30-300 gigabytes
thanks for your input!

You have to remember that copy and paste means that the OS must cache the data you're trying to copy, and this in turn means that it has to have enough free space to do so.
If your hard drive is almost full, OS X will have to move small files or file fragments around before it can cache chunks of the files you want to copy and paste somewhere. It has to cache them, in case you (or an exterior cause) interrupts the copying and pasting, so as not to damage the files.
Moving files is another matter, since the files don't actually change places, they're just indexed as being moved to a different folder or directory.
Bottom line is, the bigger the quantity of data you want to copy and paste, the more free space you need.

Why Does My Mouse Slow Down?

Lifetime Windows user recently switched to Mac. I plugged in a USB mouse and as I get close to whatever I am looking to click on and naturally slow down, the cursor slows down exponentially. I read something about this being how macs are, but want to verify that and see what can be done about turning that off if it is the case. It is just awful in my opinion.

Trey B wrote:
So you can minimize LabVIEW 8.5 and the speed returns to normal? What operating system are you using?
Yes, if I minimize LabVIEW (or switch to another program), my mouse speed returns to normal. I'm running Windows XP w/ SP2, and using a Logitech Trackman Wheel.
Marc A wrote:
I noticed this once with Google Earth. Turns out my mouse drivers were set to disable acceleration in games. This slowed the mouse down when Google Earth was in focus. I'm not sure if any drivers treat LabVIEW as a game, but it's worth a look.
Your fix worked for me. I turned off the "Disable Acceleration in Games" setting and it worked great. I don't program at home, so it's not an issue for me, but I imagine this could be an annoyance for anybody out there that also does any gaming. Just an idea for NI.

Why does my Macbook slow down every 4-5 seconds?

I am a big gamer nerd, and recently i have been moving over from x-box to computer.
I have recently noticed when i am playing high graphics games, or any game that takes a good amount of graphics, my computer seems to slow down alot every few seconds.
For Minecraft, i can play it on all the best settings and it will run perfectly fine for 3 seconds, then i get about 8 fps for one second and it repeats. It gets really annoying especially when it is in an intense moment, (or when it makes me fall into lava) This also becomes a big concern on games like Left 4 Dead, it makes these games (that my computer CLAIMS it can handle perfectly) almost unplayable.
This seems to become more apparent as my computer heats up.
Why does my computer do this? and Is there a way to make it stop?

Good that "big gamer nerds" are starting to use the Mac. Not long ago, there were hardly any good games around. Going backwards, yes, it's going to make the MBP run hotter. It's using the max amount of everything running.
To really help you, we would need the exact model of MBP. For example, if you have 15 or 17", you need to make sure you're running with the discrete video card (nvidia or AMD) instead of the integrated Intel version (which is good enough for TV viewing and web browsing). Also, you need to make sure you maximize memory. When I play a game (I only play Starcraft), I shut down all other programs, especially anything that runs in the background (like a twitter feed, though that really doesn't use too many resources). You can use Activity Monitor (it's in your Utility folder) to see what's sucking resources on your computer.
Remember, the game companies want to sell as many games as possible. So they give computer spects that will just barely run the game if you tweak every setting. You want to be way over the minimum settings in processor speed, memory, disk space etc.
Minecraft has known framerate issues on the Mac port of the game. It has nothing to do with you, your Mac, or anything, but the quality of code from the developer.

Why does my MBP slow down throughout the day?

If I reboot my MBP it will run very fast, nice and zippy. But as the hours go on it seems to slow down to a crawl. I am noticing this in particualr in PS where I can run a program called Portraiture (for example) that will run almost instantly after a reboot and then hours later will take as much as 25 or 30 seconds to run.
The only thing that I have noticed is it does seem to correspond (possibly) with an external hard drive I attach to it frequently. I did this morning again and noticed it starting to slow shortly after. Ejecting the disk and unplugging it doesn't help, but ejecting it, unplugging and rebooting does help. (Though I don't kow if it is just the reboot that is helping and not neccesarily the disk) This ext HD is one that was used with my PC and is now being used to transfer files from the old PC to the new Mac. Could this be the problem? Have you ever heard of this being an issue?
I just used a tool called the band aid tool- this is something that is used for retouching. When using this tool it is typically instant but just now it took about 45 seconds for it to do it's job. I looked at the activity monitor and it was showing only 2% memory usage at the time.
This seems a bit odd to me.
MBP, Lion, 2.3GHZ, 8GB RAM.

Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Appearance/Themes).
* Don't make any changes on the Safe mode start window.
See:
* [[Troubleshooting extensions and themes]]
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Why does my animation slow down in safari?

i've created an animation at 75 fps. when i open the .swf
file with safari the animation is slowed down. why is this?
also, Explorer can't even open the file. i suppose i need a
flash player for Explorer. I should probably also upgrade from 5.2,
huh? hahahaha

And yet I have built an entire career on animation with
flash. I will admit, being a toon boom user,
the difference is huge - TBS has a lot more desireable
features - but flash is flash - it is pretty
convenient that the entire world browsing the internet has
the flash player - and flash does have
one of the most intuitive timelines ever. TBS is still in the
dark ages with exposure sheet style
animation - it's traditional and that's fine, but serves very
little purpose in regards to
computer-based animation.
The general statement that flash is not an animation tool is
like saying that a ferrari is not for
driving.

Does LR 3 slow down when there's a lot of photos?

I've been adding a ton of photos into my catalog recently (I now have 23 thousand photos) and I'm wondering if having a lot of photos in my catalog will slow Lightroom down.
I've been recently worried about the speed of LR because it has been slow to respond lately, and It's now consuming 850MB of ram when I open a 14Mp Jpg without any adjustments of any kind.
Thanks, and if you have any suggestions to how to make Lightroom faster, send them this way.

Some has slow process when a large number of photos are available but I think it's most related to their OS configuration ? Actually it would be a good idea to "optimize" the LR configuration : good RAM value is 4 Gb, memory cache have to be as large as possible, HD's (not all on same disk : system and pictures), SSD and/or RAID aso.. Minimum values indicated by Adobe are really the VERY LOWEST to use. And as other already told : optimize your catalog regularly.
You'll find on many sites good tips to make the best possible configuration, avoiding in principle a slow response of soft.
An experienced professional photographer, Martin Evening, has published a (cheap) book about LR3; it could be considered as one of the LR3 bibles. There are many tips given, difficult to transmit in detail on a forum like this one.
I never have found any problem with slow down of LR. But my biggest library, personally I use several libraries, is under 40000 !
Cheers.

Why does Firefox performance slow down after starting Jack server?

Hello,
I started configuring my audio on my system. So, I want to have jack working (not jack2, to work with wineasio) with best sound quality with all sound routed through jack. When i start jack server with this command and settings:
killall jackd;killall pulseaudio;jackd -R -t 1000 -d alsa -P hw:0,0 -r 48000 -n2 -D
Firefox slows down, opens new pages slow and the scroll down is very very slow. I had this issue with other distros too. I suspect that it has to do with realtime ( which i need for my audio related apps like traktor through wine, ardour, ableton through wine etc) without being sure about it. Any idea why this is happening?

zabrielza wrote:I had this issue with other distros too.
This smells like hardware problem. Do this:
1. Kill pulseaudio, jack, and make sure they are killed
2. Make sure you do not renice anything or apply other such tweaks
3. Run jackd -d alsa
4. Use your system
5. If unsatisfactory, try jackd -d alsa -p 1024 -n 3
6. Use your system
Jack runs with realtime priority by default (no flag required), and we still use the audio group to provide that privilege. I also do not advocate the realtime kernel, but you may try it. Jack not functioning well (i.e. hampering other tasks significantly) on a standard kernel is cause for concern.
You can read/grep your dmesg and systemd journal for suspicious messages. You may try running real-time audio tasks in another operating system with your hardware, and upon success may proceed to debug the problem on Linux, possibly with the help of the alsa developers.
Or better yet, grab a supported semi-pro external audio device if jack is important for you. However, this may not help if the problem is somewhere deeper, e.g. at the hardware interrupt level.

Does an Ipad slow down as you use up its storage capacity

I am thinking about getting the ipad 3 that's coming up on march. I will get a 64 gb Ipad and will put a lot of music, movies and apps

There has been no confirmation that there will be an iPad 3 in March.
In general, filling up the storage capacity will not slow down the device by a noticeable amount. I speak from experience

Why does my footage Slow down and loose audio when imported to after effects cs6?

Whenever I import video of any kind into after effects, it slows down and looses audio. It happens for every video. The weird thing is, it seems like it doesnt happen to anyone else on the internet. CAN SOMEONE PLEASE HELP ME PLEASE!!!! I am about to cry. I cant do anything with this stupid software! If there is a solution please tell me. Its really annoying.
extra info-
On Mac
mov. Files
H.264 codec

Slows down when? When you preview? Do you know how to preview?
If you are pressing the space bar to preview the video then the behavior you are seeing is normal. AE will not playback in real time with autio unless you do a ram preview (look it up). You must learn to use the software.
Start with the three videos on this page: Basic Workflow
Or check out these resources: AE Basics

Why does my application slow down?

Hi,
I'm designing a LabVIEW PDA application which has to receive, display and save data. One data is received every 30ms through Bluetooth (the other side is a microcontroller). My problem is that after about 5 secondes the LabVIEW application slows down and my system is not real-time any more. Is it because of the shift registers? I don't have a lot of knowledges in LabVIEW and I hope somebody will be able to guide me toward a solution.
Thanks in advance

Your image is not good enought to really see what's going on, but nothing seems very efficient from what I recognize.
You don't need the flat 4 frame sequence structure at all. Simply delete the read globals in the fourth frame and use a wire from the value a few frames over. Now execution order is fully determined by dataflow. Delete the sequence.
What's all that song and dance to get a DBL from a string? (looks like "string to byte array...split string...combine...delete from array(?!)...to DBL") I think all you need is a "typecast" and a "to DBL". (I've see that before but it is very hard to comprehend why people use "delete from array" and then only use the "deleted portion" output to get a subset. What's wrong with "index array" or "array subset"????)
You are growing four arrays without bounds, this is very expensive. Do you have any idea how long the arrays will get in the worst case scenario?
you are reading the dt global four times with each iteration. I doubt it will ever change during the loop, so read it once outside the loop and wire it to all users.
Why are you constantly building new waveforms? You might as well just graph the arry direclty and set x0 and dx once with a property node before the loop.
What determines the loop rate?
Why are you bundling the four arrays into a cluster at the end? Keep the datatype simple! For example you could use a single 2D array.
What is going on in the other frames of the big sequence?
Why on'y ou attach your program, it would be easer to inspect.

Why does my ipod slow down playback?

I have a 3rd Gen iPod Classic which has worked flawlessly until just recently. It has started to play back my mp3 files at a slightly slower tempo but enough that it is really disconcerting. Does this mean that the unit is dying? Like maybe the hard drive is on its way out? I know newer versions have a speed control. Not mine. Has anyone out there had a similar experience? Any help here would be greatly appreciated.
