IMac with 4GB - Parallels partition slowing down

I have an iMac mid 2007 with max memory of 4Gb. I run Windows 7 in a Parallels partition. on both sides I do little else than browse and use Office. Since installing Mountain Lion, the Windows system has been runing slower and slower. Advice from Parallels is to clear the temp folder. They don't seem concerned about the size of the partition.
My question is: is there something I can do to get the performance back up to reasonable speed? Put another way, how can I tell whether the hardware I have simple will not support Mountain Lion and Windows 7 together. I have avoided moving to Windows 8, but do have Office 2013, and it drags.

Upgrade the RAM, 4GB is a minimal amount of RAM these days. To see how you RAM is being used, carefully read Apples instructions on Activity Monitor. You can find them by clicking:

Just upgraded an iMac with 4GB Memory and Intel Processor from 10.6.8 to Mavericks and Quicktime plays m4v files with stuttering audio

I just upgraded an iMac with 4GB Memory and 3.33 Ghz Intel Core Duo Processor from 10.6.8 to Mavericks. I now have Quicktime 10.3 which plays m4v files with stuttering audio. This is a nightmare as I use Quicktime a lot in my research. I have seen similar threads but so far only reporting the problem. For now I have installed Quicktime Player 10.7 (which appears in utilities, leaving Quicktime 10.3 in the main applications list) which plays the same videos with no problem, but it would be good to know if anyone has managed to find a workaround at all, or know if Apple have plans to do anything about it?

Slow performance after installing Yosemite on an older Mac is often caused by inadequate memory. Although you can install the upgrade on a Mac with 2 GB of memory, experience has shown that at least 4 GB is needed for full performance.
Select About This Mac from the Apple menu. If you have less than 4 GB of memory, and your model has upgradable memory, install as much as it can take, or at least that much. Any reputable RAM vendor will have a web form in which you can select the Mac model and be directed to compatible parts.

Since downloading OS X Yosemite I have been having issues with Netflix. Video slows down which causes the audio to go out of sync. Netflix plays ok on ipad which makes me think it's the software which is the issue. Has anyone else had this issue?

Try this:
Go to System Preferences - Bluetooth. Delete the keyboard from the list of devices by pressing the "-" button. Take the batteries out of the keyboard and reinsert them. In Bluetooth Preferences press the '+" button to add the new device. If the keyboard begins to pair, click the word "pair" and type in the passcode. Press return. The keyboard is now paired.
If the mouse is not pairing, try this: shut down the computer completely, unplug any USB mice, then turn off the power to the bluetooth mouse. ONce the computer starts up again, wait for the pop-up looking for a mouse. Turn on the power to the bluetooth mouse. It should work normally now.

Will having another OS on partition slow down my computer?

I have an early 2013 iMac (base 8gig RAMs, 1 TB harddrive, 2.7 GHz) that came with Mountain Lion. I want to partition my harddrive to install Mavericks. Will this slow down my computer's performace in any way? Also, if I keep going back and forth between Mountain Lion and Mavericks, will it harm the computer? Thanks in advance.

It may slow down your system slightly, depending on how full it is. With a spinning hard drive, it's the fastest at the outside, which is where the Mountain Lion partition is. So the Mavericks partition will be slower, but it may only be 10% to 15% slower for disk-related activities (assuming the disk isn't all that full).
But you also need to decide how you're going to handle your data: If you have a home directory on each partition it's going to be a pain. However if you DON'T (and attempt to share it), then applications that update their database (i.e. Mail, Notes, etc.,) may have data loss or otherwise corrupt things. So that's a risk.
Any reason you want to partition the drive? For the vast majority of users, Mountain Lion to Mavericks is a smooth upgrade. My recommendation would be to have a FULL backup (Time Machine, AND make a clone with SuperDuper! or Carbon Copy Cloner to an external drive). Then just upgrade. On the off chance that things do go terribly, you can just clone your drive back.

Windows 7 Pro on iMac (mid 2011) and network slows down

We have an office with about 8 mid 2011 21" iMacs running Windows 7 Pro courtesy of Bootcamp. The machines boot quickly and all programs open quickly. They each have from 2 - 4 mapped network drives to a 2012 Windows Server 2008 R2 HP GL380 server on-site and are wired with Gig Ethernet HP business class switches). The users' Documents, Desktop, and a couple other directories are re-directed to the file server using an Active Directory Group Policy Object (GPO).
A couple of the computers will regularly start to slow down after only 20 or 30 minutes of use. The rest have occasionally experienced it but it's always independent of others experiencing the slowdown. The computers with the more regular slowdowns I've also booted into OS 10.7.x and the transfer rates to the same file server are fast and consistent. BTW, all computers are current on Windows updates and Apple updates.
I've tried some of the suggestions I found here: http://www.neowin.net/forum/topic/950538-running-windows-7-via-bootcamp-on-mac-m ini-slows-down-over-time/
1.)
Disable all property's that has something to do with "Offload" under advanced on the nic properties.
Also disable "Recieve Side Scaling".
And set "Speed and Duplex" to auto.
2.)
Turn off windows feature "Remote Differential Compression" (Uninstall) under "programs and features".
3.)
Run fallowing command in cmd:
netsh int tcp set global autotuninglevel=disabled
netsh int tcp set global chimney=disabled
i ran disabled on every setting i could.
so it looks like this now:
C:\Users\tab>netsh int tcp show global

Chimney Offload State : disabled
NetDMA State : disabled
Direct Cache Acess (DCA) : disabled

4.)
Uncheck fallowing under your local area connection properties:

With all of that said, do any of you have any suggestions of what to check?

Tethering with AT&T, any slow down with increased use?

I am between buying a Iphone4 and a DroidX. The tie-breaker likely is going to be tethering. Apparently on a DroidX with Verizon, after 5 gigs, the intenet slows down to a crawl, something I can't live with. I gather there is no slow down with AT&T, you just pay more, $10 per gig. Do I have that right? Does tethering the Iphone4 work as well as a wireless card? Thanks.

It works fine...did I mention it was EXPENSIVE!

Really stuck with speeding up and slowing down clips

Hi gang,
I have been reading the Final Cut manual for the last hour and fooling around with my clips, but I can't get the effect that I want.
I have a clip (CGI of a star field moving towards the observer) that I want initially to be frozen, then I want the clip to accelerate rapidly, and then end at about double normal speed. I thought I would be able to use keyframes and specify the playback rate at given points, but that option doesn't seem to exist. I have been playing with variable and constant speed settings, but these don't seem to work either.
Ideally, the clip would go like this:
1) first frame of original footage is frozen for 2 seconds.
2) the original footage then begins playing, accelerating rapidly from frozen to double speed over 2 seconds.
3) remainder of original footage plays at double speed until complete.
I feel like I am missing something obvious, but I can't get it to work!
Any suggestions appreciated.
Cheers!

Dude, I have the same problem. I found a picture/text tutorial on how to slow down, speed up and reverse all in one clip w/o chopping it up, but it was for FCP 4. I have 5 and when I ramp the green line down it speeds up, doesn't slow down. Is it just me or is the effect changed from FC4 to FC5.
I'm looking for a great video tutorial for FC5 or similar on how to slow, speed up and reverse a clip using the Time Remap Tool in FC.
If it's a DVD I have to buy so be it.
Thanks everyone.

The Internet connection with WRT54GC V2 is slowing down about time.

I upgraded the router to the newest firmware (1.01.0), but the connection with time still slowing down. I turn the router off and then on, and the connection is fast already. After 1 or 2 days the connection slowing down again. What can I do?

Connect your computer straight to your modem and check if you face the same problem...If you don't face any problems through the modem, hard reset your router...
Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...If you still face the same problem get your router replaced...

SharePoint with 100 custom Features slow down?

Hi,
i am developing SharePoint features and after i deploy to my local maschine around 100 custom features the sharePoint slow down until timeOuts.
My dev maschine is an i7 2.5 GHz, 16 GB ram, SSD
My SP is an SharePoint 2010 SP2
Why this happened? is this normal?

Typicall depends on what the featuers do. If you enable developer dashboard (
http://msdn.microsoft.com/en-us/library/office/ff512745(v=office.14).aspx ) you'll find out if there is anything specific causing the slowness.

Tip for upgrading from MBP to iMac with Leopard & Parallels Boot Camp

Here are some pointers based on my recent experience upgrading from a MacBook Pro to an iMac, under Leopard and with Parallels using a Boot Camp partition for Windows.
First, you do not need to create a Windows partition on your new computer. You will use Boot Camp Assistant to do that - it can dynamically resize your existing Mac OS X partition without destroying it. (I initially used Disk Utility to create a Windows partition but it wasn't recognised properly by Parallels and also the Mac wouldn't boot from it).
A great way to simplify getting your old installation across is to make a Time Machine backup onto an external drive. Yes, you could also use start up your old Mac in Target mode (hold down T key when you start it), then start the new Mac and copy your settings over. But in my case, the new iMac (a refurb) came with Tiger installed on it while my old Mac had already been upgraded to Leopard.
I started the new Mac using a Leopard install CD (holding down the C key while starting). Then I chose to restore from a Time Machine backup instead of installing from CD, and soon had a functioning Leopard installation on the new Mac. Well, almost.
Next I used Boot Camp Assistant to create a Windows partition on the new drive. The old Mac's partition was only 10 GB in size, but I made the new one 31.9 GB in size (so I could stay under the Windows limit of 32 GB for FAT partitions). I then quit without installing Windows.
On the old Mac, I used an external drive formatted as FAT and used Disk Utility to 'restore' my Windows partition to the external drive. Next I plugged that drive into the new Mac, and restored the external Windows partition to the new Mac's Windows partition. So far, so good. However, Parallels would not start this installation of Windows, and the new Mac would not boot into it (holding down the Option key at start-up did not show me a Windows drive).
I tried doing a repair of the Windows installation using a Windows install disk but that did not work. What did work was the following: I booted from the Window install CD, then started a new installation. I asked Windows to format the Windows partition on the new Mac, then powered off the new Mac as soon as Windows started copying files. Next, I rebooted the new Mac into Mac OS X, started Disk Utility, and again did a restore of the Windows partition on the external drive to the Windows partition on the new Mac.
The final step was to reboot the new Mac into Windows directly so that I could load drivers from the Leopard install CD. [I haven't done that yet, so I'm not sure it's necessary].
Hope this helps!

Sounds solid to me. If the Glyph was connected on a firewire port that is. This would free up the bandwith that way but actually it is hardly an issue with the Duet considering the limited inputs. But using the Glyph as a backup for your projects is good wise idea anyway.

Will creating two boot partitions slow down a HDD?

Hello,
I'd like to have 10.8 and 10.10 on my Mac Mini 2012 for two reasons:
- I have stuff that only runs under 10.8
- I find 10.10 slower (or don't you agree?) in normal use, even the Finder, opening folders and apps etc.
I don't need 10.10, but I would like to have it there, to play around with it and explore it some more over the years to come. But I only need 10.8
Will making two partitions on one Hard Drive make the HDD slower? If so, I would either omit 10.10 or use an external for 10.10.
Thanks.

@ BobHarris:
Would you expect that the RAM can mess up several Headers on the Volume, so that Disk Utility even says, it can't repair it, I need to format the drive?

I am in Germany and bought it at a big chain of electronic store's here. But it was and is still available everywhere in Europe from internet stores as well. I have the i5 2012 model (the i7 models of 2012 were just sold out, they are clearing the shelves. Then two exemplars reappeared in Germany, but at a ridiculous price of 900-1000,-EUR, while the Initial price was something around 829,- (it even dropped to 650,- after one year, very crazy. And I am speaking of the i7).
If you are in Europe (for work or so):
2012 i5 http://skinflint.co.uk/eu/apple-mac-mini-md387d-a-late-2012-a856420.html?t=alle& plz=&va=b&vl=de&hloc=at&hloc=de&hloc=pl&… (prices in pounds, for EUR, go to their partner price comparison pages). You also have to change the shipping destination.
If you scroll down here, soue will find the i7-models of 2012 as well http://skinflint.co.uk/eu/?fs=mac+mini+2012&in=
If there is no such comparison site in the US, then you could try to find one shop, that you can talk into importing it the US. With older Macs (PPCs) I remember there was a small button to change the AC-power form EU to US, I don't know, if the Mini maybe adjusts automatically, or if they produce a central european and british version (British power adapters/sockets have another shape then in the rest of the EU, so they would at least include another power cable).
For a private person, the shipping costs from Germany to the US would be about 35,-EUR (x1.06 = USD), so I guess an online store would not have much higher shipping costs. Problem will be the customs duty taxes, I guess?

Problem with InDesign server - Server slows down fast

My javascript code iterates the pages of the InDesign Document and searches for the text frames with some special character style.
I found some samples from Jongware :
sourcelist = app.activeDocument.findText()
and
sourcelist = app.activeDocument.pages[p].textFrames[f].findText();
if I use the first variant the memory goes to ca. 1.2GB (the server has 4GB), the search is completed in ca. 2 minutes but InDesign Server works incredibly slow.
The problem is I have to find a page for each text found.
If I use second variant the memory goes high slowly and so each iteration needs more time.
After 300th page InDesign Server needs up to 30-40 seconds to process the page.
(First pages are processed 3-4 per second)
I tried several possible implementations, like
for each page
     var actualPage = pages[i]
     for each frame
          var actualFrame = frames[i]
          var sourceList = searchText(actualFrame)
               parseText(sourceList)
or
var actualPage=null, actualFrame = null, sourceList = null;
for each page
     actualPage = pages[i]
     for each frame
          actualFrame = frames[i]
          sourceList = searchText(actualFrame)
               parseText(sourceList)
I've tried functions with local variables. Nothing changes.
Processing of the first 50 pages is really fast, but the test document has 630 pages.
And I have no ideas how to make InDesign continue to work fast.
Have someone had similar problem? Any ideas?

To clarify my comment on pages:
JavaScript objects referencing a native InDesign object have an internal representation for their "address" in the DOM, a textual form (similar to an XPath) is available via toSpecifier(). The specifier starts at the document and then follows collections (e.g. pages) and collection accessors (e.g. itemByID()) to finally reach the same object.
You can see that the specifier of the document before and after the close/open roundtrip changes in CS5 or later (different document ID), where CS4 used a different specifier form (itemByName() for the document) . The renumbered document ID renders previous references to the same page invalid - see the isValid property. If you want to revive such a stale object reference across close/open, you can remember the page ID and use your reopened document's myDoc.pages.itemByID() method to get to the same object.
Regarding your other performance problem: print the output of the ExtendScript helper function "$.summary()" before and after the code sequence in question, or compute the differences. You may want to precede that with two explicit calls for the garbage collection "$.gc()" - yes, double invokation seems to be more thorough. Sometimes you find memory leaks that way, for example caused by the javascript "closure" design pattern (all those "Workspace" objects).

Thunderbolt with Pegasus R4 heavily slows down boot performance of internal SSD

After connecting a Promise Pegasus R4 Raid with a Thunderbolt cable, my Mac Book Pro 2011 (Snow Leopard) needs about 60(!) seconds longer to boot from the internal SSD. Without the Raid connected, my MacBook Pro needs about 20 seconds to boot. When I press the power button, the display of the MBP is more than 20 seconds black before the bootsequece starts. I shorly can hear the CD drive beeing checked after pressing the power button - as usual. The RAID is the only periphal connected via Thunderbolt. No softwareupdates are available. Raid and SSD are pretty fast after the system booted. Is this behavior normal?

Mrvoeg,
I appreciate you posting that information. Here is what I got with my setup.

Old house with plaster and lath slowing down airport express?

My airport express worked fine in my previous house. I recently moved and my new (older 1920's) house construction seems "thicker" and the wi-fi drops all the time. The house also may be a bit bigger but it seems like such a radical change from how well everything was working at the previous place. When I play itunes over the wi-fi to the living room surround sound it drops on and off as well. I have to go into the hallway to get a connection for my ipad from the bedroom. This is all driving me nuts! Do I need to get an airport extreme? If so will it really make a difference?

Plaster and metal lathe walls are like steel for a wireless signal.
Unfortunately, this is a "worst case" scenario for wireless in a home. In this type of constuction, you really need to have line-of-sight between your wireless router and wireless devices....or very close to it.
or
You need to run Ethernet cabling to the areas where you need more wireless signal and add AirPorts in those locations to provide more wireless coverage.
If you cannot run the Ethernet cabling, it is possible that Ethernet powerline adapters might be able to send a signal over the existing AC power lines in the home....but I'm not optimistic about this if much of the wiring is "original"
A different router will not help since the signal power of wireless routers is limited by law...they are all about the same.
If it were me, I would call in an IT specialist who can come out to survey the house, take some measurements with test equipment, and propose the right system for your needs.
Otherwise, trial and error can result in a lot more headaches..and more expense as well.
