Snow Leopard slower than Leopard??

Hi
On 5 year old macbook with 1GB ram leopard was upgraded to snow.
Since the upgrade the macbook is going slower... What can be the reason for this?

Under some circumstances it's may be possible that Snow Leopard appears slower than Leopard. One technique to boost power in Snow Leopard is to transfer compressed data from the hard drive in to the RAM, Cache and CPU environment. Apples ulterior motive behind this idea was, that in the past the CPU performance grow bigger than the transfer performance from hard drives. In other words Apple thought that the additional benefit of transfer data quicker from a hard drive yield more profit than the cost the CPU have to "pay" to decompress the data. In an old system, e.g. with a single core CPU, this benefit maybe isn't present and the result maybe turns in the opposite direction and you notice a decrease of system performance.
Bye Tom

Snow leopard slower than ever

Hello there,
Since I've installed Snow Leopard ( one year ago...) my mac is slower than ever at the launch ( more than 40 seconds).
I did my best to clean it with Snow Leopard Cache Cleaner, OnyX. ( It fixed my problem of the multicolored circle which was boring me on iPhoto or When i was on Internet...).
I've checked and fixed the disc, it looks ok.
I've delted the soft which started at the launch
I'd like to upgrade my mac to Lion... but first I need to find what makes it slow.
What's wrong please?
Looking forward hearing from helpers

Check this out... Closing down is very fast... here are the errors for the launch
How can i do? Thanks

Leopard Slower than Tiger?

I've noticed a definite difference in start-up time - Leopard 27-28 seconds, Tiger 16-17 seconds. Also general navigation and reaction times seem slower to me. Anyone else notice this? And is this to be expected?

Hi tksuther;
Journaling is a process of keeping track of data being written to a disk. It provides protection in case of sudden shutdown of the system so that the disk can be restored to a valid state.
When journaling was introduces to OS X, I did some very extensive testing in an effort to see if journaling was taking up noticeable amounts of resources on the system. After doing my testing I discovered that the difference between disk with journaling turn on or off was so small I could not realistically measure it. The difference was smaller then variability in the test on the disk. Hence I say that it not measurable and I alway leave it turned on.

Anyone else's Snow Leopard running slower than version 10.5?

My hard drive crashed a few weeks ago and I decided to have the Apple Store upgrade my operating system to 10.6.3 and I have found that it's slower than the previous version. Also, Adobe InDesign doesn't print from the new version.
Is anyone having these problems?? This could make me revert back to a PC

Well, yes, if it was a new HD and your old drive was dead, they would have had to do an install from scratch.
If the old drive was still running they would have done an upgrade & migrate unless you told them otherwise. Problem with migrating is often higher powered apps like CS3, Final Cut, Aperture, etc. don't run well if at all and you end up having to do an erase & install anyway.
What is the exact model iMac you have, and how much RAM? What HD did you buy?
CS3 is old at this point and my understanding is Adobe does not support it on Snow Leopard. Are you experiencing the slowness just with CS3 or with everything (say, Safari, Office, iTunes, etc?)

Snow leopard is 30-50% slower than Tiger???

I've recently upgraded from Tiger (10.4.11) to Snow Leopard (10.6.4) and to be perfectly honest, I'm real disappointed. I'm a game developer and the first thing I noticed is that all my games now run 30-50% slower than in Tiger. I've read that this is caused by SL's OpenGL drivers.
1. Is anyone else experiencing this?
2. Is Apple working on a fix for this, and if so, how soon can we expect to see it?
3. Short of buying more hardware, is there anything I can do to fix this?

Sorry if I wasn't clear, the issue is that the games (and the game editor) run 30-50% slower on MY computer (specs below). My development machine has become 50% less useful thanks to SL.

Why is Mac OS X 10.7 so much slower than Snow Leopard? It isnt smooth, applications are slow and most dont respond, and dowloads take hours, minutes.

Something is seriously wrong with your installation or you are critically low on RAM, like below 2 GB.
How much RAM is in your machine?
Have you tried a Recovery?

File sharing on a MacMini with Snow Leopard Server slower than on a G4

We've decided to replace our old file server, a G4 2x450 (running Mac OS 10.4.11 (client!) with 640 MB of RAM) by a MacMini Server, running Mac OS X Server 10.6.2.
The Mini runs the OS out of the box (I re-installed it to avoid mis-configurations). What's frustrating is that the Mini is slower than the G4.
Attached to the Mini is a RAID 0 MacPower Taurus with 2x1,5 TB SATA drives. The G4 is sharing a 650 GB P-ATA RAiD 1 internally attached via a 64bit ACARD.
While the G4 receives about 32-35 MB/s over the network (using a 5GB file for the test), the MiniServer doesn't exceed 25 MB/s.
A local copy of the same file isn't much faster on the G4, but on the Mini the copying speed is more than 70 MB/s. So. on the Mini copies over the network are only little more than 1/3 of the local copy speed!
So the problem is not the speed of the drives, the speed of the network - it's the data transfer from the network interface of the Mini to the FireWire interface.
The network is well configured, using a HP ProCurve 1810 managed gigabit switch. Both servers were tested under same conditions in the same network.
I would appreciate any help or idea?

I have the same experience.
But did you try to write to the local MacMini drive or to the Fire attached Raid?
I found, that my internal MacMini drives are fast over the network, but as soon as it comes to Firewire drives on the MacMini over the network, it's only half speed.

Does Snow Leopard have a lower version of Safari than Leopard?

I'm just about to upgrade from Leopard to Snow Leopard and browsing through the booklet that came with it I saw that it says it contains "Safari 4." They advertise this as though it is an improvement, but I currently have Safari version 5.0.6. Is it possible that Snow Leopard uses an older version of Safari than Leopard does? If so, will it downgrade my version when I install it? How could I prevent that? Or could I upgrade Snow Leopard after installation to run Safari 5 or more? Is there a big difference between the two versions? The whole pont of the upgrade, of course, is to get better, newer versions of everything.

You are looking at information issued when Snow Leopard first came out. Your install shouldn't downgrade your Safari but if it does you can simply update it using Software Update. The highest version of Safari which runs on Snow Leopard is 5.1.10

Leopard much slower than Tiger and buggy

Hi,
I run Leopard on PBG4(1.67MHz) with 1GB of ram and iMAC G5(2.1) with 1.5GB of ram and I am experiencing incredibly poor performance.
Booth machines are slower than usual and I cannot find reasons why. On my PB I am constantly getting spinning beach-ball and interestingly my fans are running all the time. Something that was not the case with Tiger. Importantly: I did not install any new SW. I use only MS Office and iWork/iLife.
When I did a little bit of investigation I found out that Safari is taking up a lot of processing time. Even when is idle it takes up to 40%-50% of CPU time. And that is the case with PB and iMac.
Furthermore I have encountered strange behaviour with PowerPoint and Excell and here is one line from console.log:
5.11.07 13:14:58 [0x0-0x49049].com.microsoft.Excel[591] Mon Nov 5 13:14:58 Jabucek.local Excel[591] <Error>: The function `CGPDFDocumentGetMediaBox' is obsolete and will be removed in an upcoming update. Unfortunately, this application, or a library it uses, is using this obsolete function, and is thereby contributing to an overall degradation of system performance. Please use `CGPDFPageGetBoxRect' instead.
Are we having serious problems with Leopard? Was this product premature to be released on the market? I am seriously thinking to downgrade back to Tiger.
Do you have any similar experiences?
Matej

Hi,
I only came to this thread because I was searching for items on a similar Console message:
"/System/Library/CoreServices/SystemUIServer.app/Contents/MacOS/SystemUIServer: The function CGSDictionary is obsolete and will be removed in a Tiger update. Unfortunately, this app, or a library it uses, is using this obsolete function, and is thereby contributing to an overall degradation of system performance."
As you can see, I'm still running Tiger - and I'm worried that installing Leopard will not make this odd message go away - It and another two with a similar message are generated everytime I start up..

It's been a while since I upgraded my system. Is there anything I should do before upgrading from 10.5.8 to Snow Leopard other than backing up my files? The transition should be pretty seamless, right?

How to Install OS X Updates Successfully
A. Repair the Hard Drive and Permissions:
Boot from your current Tiger Installer disc. After the installer loads select your language and click on the Continue button. Then select Disk Utility from the Installer menu (Utilities menu for Tiger and later.) After DU loads select your hard drive entry (mfgr.'s ID and drive size) from the the left side list. In the DU status area you will see an entry for the S.M.A.R.T. status of the hard drive. If it does not say "Verified" then the hard drive is failing or failed. (SMART status is not reported on external Firewire or USB drives.) If the drive is "Verified" then select your OS X volume from the list on the left (sub-entry below the drive entry,) click on the First Aid tab, then click on the Repair Disk button. If DU reports any errors that have been fixed, then re-run Repair Disk until no errors are reported. If no errors are reported click on the Repair Permissions button. Wait until the operation completes, then quit DU and return to the installer. Now restart normally.
If DU reports errors it cannot fix, then you will need Disk Warrior (4.0 for Tiger) and/or TechTool Pro (4.5.2 for Tiger) to repair the drive. If you don't have either of them or if neither of them can fix the drive, then you will need to reformat the drive and reinstall OS X.
B. Make a Bootable Backup Using Restore Option of Disk Utility:
Open Disk Utility from the Utilities folder.
Select the destination volume from the left side list.
Click on the Restore tab in the DU main window.
Check the box labeled Erase destination.
Select the destination volume from the left side list and drag it to the Destination entry field.
Select the source volume from the left side list and drag it to the Source entry field.
Double-check you got it right, then click on the Restore button.
Destination means the external backup drive. Source means the internal startup drive.
C. Important: Please read before installing:
If you have a FireWire hard drive connected, disconnect it before installing the update unless you will boot from this drive and install the update on it. Reconnect it and turn it back on after installation is complete and you've restarted.
You may experience unexpected results if you have installed third-party system software modifications, or if you have modified the operating system through other means. (This does not apply to normal application software installation.)
The installation process should not be interrupted. If a power outage or other interruption occurs during installation, use the standalone installer (see below) from Apple Downloads to update. While the installation is in progress do not use the computer.
D. To upgrade:
Purchase the Snow Leopard Retail DVD.
Boot From The OS X Installer Disc:
Insert OS X Installer Disc into the optical drive.
Restart the computer.
Immediately after the chime press and hold down the "C" key.
Release the key when the spinning gear below the dark gray Apple logo appears.
Wait for installer to finish loading.
E. If updating:
Download and install update(s)
Use Software Update, or
Download standalone updater(s).

Why does Lion seem slower than Snow Leppard?

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.

Leopard SLOW on PB

Hi all,
I posted a similar thread about this time last year, when Leopard was introduced. I found it to be painfully slow on my 1.25 AL PB. Unfortunately, none of the tips really got me anywhere, so I went back to Tiger (which runs GREAT on my PB) and left it at that. It's now been nearly a year, and there have been several updates to Leopard, so I thought I'd give it another shot. This was a fresh install of 10.5, then all the updates installed bringing it to 10.5.5. It is still PAINFULLY slow! I've disabled Spotlight indexing, Dashboard, and used Cocktail to trim down anything I don't need. Now, I know others have said that they installed Leopard on their G4 machines (some even older and slower than my PB) and said they've had no problems or slowdowns at all. I've ran XBench with both 10.4.11 and again with 10.5.5, and found some interesting results. Scores for nearly every category relating to processor, memory, and graphics performance was cut IN HALF after the installation of Leopard. I'll throw some numbers out for example....
CPU Test
Floating Point Basic - 1.04 GFlop/sec (Tiger), 585.79 MFlop/sec (Leo)
AltiVec Basic - 6.41 GFlop/sec (Tiger), 3.17 GFlop/sec (Leo)
Floating Point Library - 6.62 MFlop/sec (Tiger), 3.82 MFlop/sec (Leo)
Thread Test
Computation - 1.10 MFlop/sec (Tiger), 622.03 KFlop/sec (Leo)
Memory Test
System Copy - 394.66 MB/sec (Tiger), 193.25 MB/sec (Leo)
Quartz Graphics Test
Open GL Spinning Squars - 90.02 Frames/sec (Tiger), 43.44 Frames/sec (Leo)
User Interface Test - 273.76 refresh/sec (Tiger), 34.48 refresh/sec (Leo)
Overall Total - 50.69 (Tiger), 20.60 (Leo)
These are just some examples that show the most extreme differences, but the score for every category (with the exception of the disk tests) showed a significant drop with Leopard. A let a friend upgrade her 1.33 GHz 12" PB with my Leopard disk (I have the family license), and her PB was also affected with dismal performance after the upgrade. So, I know it's not just my computer, and how others with PBs and other G4 machines can say that they've noticed no performance difference makes no sense to me.
To get to my point...there has to be something going on here with the OS that's causing such a disparity in the numbers. What on earth is going on with Leopard to cause my systems performance scores to be reduced by half? There are no processes hogging any processor time (and yes, I looked system wide, not just "my processes"), I made sure there we no applications running, with the exception of XBench, and I made sure the processor speed was set to highest under the power prefs. Keep in mind, I'm not basing this solely off the XBench numbers. I can clearly see the performance problems even in normal, everyday tasks. Simply opening a new window, moving the pointer over the Dock with magnification turned on, moving a window around the scree...all are rough, jagged movements with visibly noticeable dropped frames. Opening any of the "i" applications takes a lifetime compared to Tiger (for example, iCal takes 6 hops to open on Leo, on Tiger it was 1 hop)
If anyone knows what could be causing this, has any solutions, or can tell me that Leopard just wasn't designed to run on such old, outdated equipment, I'd really, really appreciate the input. Thanks much in advance for any replies!

I tried leopard on my pb also, and wondered why the drop in performance is so dramatic. On my G5, I can set performance to highest with Leopard, but I can only select "better performance" on the laptop.
I wonder if Leopard is throttling down the cpu even when its set for "Better".
Is there a way to measure the actual cpu frequency?

Shutdown is ultra slow in Leopard, any fix?

I did a wipe and clean install of Leopard. I find the boot somewhat slower than Tiger but then shutdown is really really slow. It seems the process simply stalls as there is no HD activity and the logs simply says:

According to this the shutdown takes 3 seconds. This is far from the 60+ seconds that it really takes. Sometimes I see the "Apple-thinking" gear...
"shutdown -r now" reboots the mac in about 2 seconds. However this will not give me warnings about unsaved material. But there is no way in **** that should take 1-2 minutes to do.
Anyone got an idea on how to fix this? I got no TM/external drive or anything attached to the computer. I got a WINXP partition but this issue was here long before that. I also got some NFS mounts but the same applies to that.
Is there anyway to get a more extensive log output that what is written in system.log right now? Something must be happening???

Go to Utilities>Disk Utilities and repair disk permissions. If this fails, boot off the Leopard disk, when the language screen appears, in the menu will be Firs Aid, chose this and chose repair drive. Restart.
If the issue persists, reset the PRAM: Resetting PRAM and NVRAM
Shut down the computer.
Locate the following keys on the keyboard: Command, Option, P, and R. You will need to hold these keys down simultaneously in step 4.
Turn on the computer.
Press and hold the Command-Option-P-R keys. You must press this key combination before the gray screen appears.
Hold the keys down until the computer restarts and you hear the startup sound for the second time.
Release the keys.
Try these harmless tips and post back if it's still slow.

Leopard slow.

All, I purchased Leopard. Bought ext. HDD GUID formatted all OK with Time Machine. Backing up regularly, nicely.
My Mac Mini 1.25GHz 1GB now runs very slowly:
login/logout times very slow (Restart...45 mins)
Disk utility very slow - 40 minutes etc. as opposed to 2-5 minutes.
Installed 10.5.1. Same problem.
This was a machine that before Leopard ran faster than a P4 24 GHz Windows machine; much to the envy of my friends...
I am fastidious about fixing perms and rebooting before any update before installing.
What gives?

Same goes here, dead slow everything from boot to programloading..
iMac core2duo 2.0Ghz, 17"... not THAT old..
First time an OS upgrade is slower than the previous..

Need help removing Snow Leopard and Installing Leopard

Snow Leopard was a waste of time and money. Time I could have used for much more productive work.
How can I remove snow leopard and reinstall leopard. I have the installation disc for Leopard. Can I simply install it over the top of snow leopard?
That would solve my problem for one machine (the iMac) but how do I go back to leopard if I don't have the disk? I suppose there is dmg somewhere but I haven't looked so I apologize in advance if the answer is obvious.

Insert leopard install disk-select install.
It will wipe the drive and install Leopard-all data will be gone.
You must have a legitimate, legal copy of leopard.
If you backed up the leopard dvd, you would have to burn it or figure a way to do a network install.
