I have a new iMac and an older iMac. New one's fine, the older one is horribly slow. If I knew what to look for with Activity Monitor, maybe I could spot what processes are dragging down response times. The older iMac has a bazillion files to keep track of. Ordinary mouse clicks and changing from one running application to another takes between 10 and 20 seconds to register the change. Curiously, when the two Macs are connected to each other (older one as a Device on the newer one), I can access the older iMac's folder structure via the new iMac and response times are normal. What does that indicate? Both running OS X 10.10.5, 24" iMac mid-2007, 27" iMac late 2013.
Run etrecheck on both devices -- if you see that some modules were killed - means you are running too many applications on that device - for the amount of RAM memory you have.

Yosemite changes the way both RAM and VM are used. If you are used to having open a certain number of applications on your desk top in earlier releases with no problem - loading the same applications with Yosemite may cause Memory pressure.
Yosemite puts your entire application into RAM - unlike earlier releases where it put some in VM (pages in) if you see pages out swapping is occurring.
In order to keep active applications in RAM (those that have activity) Yosemite may compress parts of memory -- if its still not enough for active processes it Kills processes that have had no activity in a certain amount of time, only as a last resort will it swap active processes to VM.
I see 2 downsides to Yosemite: First Killing processes: Some applications may crash because the caller of a process opens it with initialization of some field then tries to call the same application after it has been killed - but is assuming it is running. Second: Compress of Memory - compression of information has one quick - very rare - the data compresses into an instruction that signifies end of data when it really isn't. Both problems would not occur if you have enough ram to run everything you have open.

Nov 25, 2015 6:32 AM in response to ckuanby PeterBphoto,Thank you! That's one of the things I needed. I'll start learning more about AM and how it can help me. I appreciate your help very much.

Nov 25, 2015 6:45 AM in response to notcloudyby PeterBphoto,Thank you for the EtreCheck recommendation and comments about Yosemite changes. The slowdown on the older 24" iMac began immediately upon upgrading it from Mavericks to Yosemite, so its symptoms fit with your remarks. The first-time report issued by EtreCheck tells me 12 System Launch Agent processes killed due to insufficient RAM and 10 System Launch Daemon processes killed due to insufficient RAM. Total RAM for the machine is 4 GB. Other aspects of the report are OK. I guess that tells me the first thing I need to change to improve the performance. I appreciate your help very much!

Nov 25, 2015 6:51 AM in response to notcloudyby PeterBphoto,Unfortunately, my mid-2007 24" iMac cannot accept more than the 4 GB RAM it currently has, according to Apple's Support documents.

Nov 25, 2015 12:21 PM in response to PeterBphotoby rccharles,OWC asserts you can get 6gig in the 2007 imac. Lots of time a larger memory chip comes out after Apple announces the machine. OWC and other try larger memory and see if it works. I'd give owc a call and verify more memory will work.
http://eshop.macsales.com/shop/apple/memory/iMac
look in activity monitor for the memory hogs. Don't run as many apps at once.
Consider downgrading. 4gig isn't enough for yosemite in my experience.

Nov 25, 2015 12:21 PM in response to PeterBphotoby Eric Root,Can you post the Etrecheck report please.
It can probably be upgraded to 6 GB. Check the OWC site.
I have purchased RAM several times from Other World Computing and have always been very satisfied with the product and service. They have on-line instructions on how to replace the RAM. OWC has also tested RAM above what Apple states is the maximum. I now have 6GB installed on a early 2008 iMac supposedly limited to 4 GB and noticed an improvement.

Nov 30, 2015 8:18 AM in response to Eric Rootby PeterBphoto,Thank you for the numerous suggestions to check out. I'm in the process of doing some of the things that apply. More maintenance and cleaning out to do. OWC Chat rep says their testing reveals usability of 6GB RAM, desp
ite Apple's assertion 4 GB is the ceiling. EtreCheck report is at this link:

Nov 30, 2015 8:57 AM in response to PeterBphotoby Eric Root,As I posted above, I'm using 6 GB of RAM on a computer Apple says only supports 4 GB.
Could you post the Etrecheck report in a reply or on Pastebin?

Dec 1, 2015 8:50 AM in response to rccharlesby PeterBphoto,Thanks for the tip. I did a chat yesterday with tech support at OWC, and the woman there said they've tested & confirmed 6 GB will work in my mid-2007 24" iMac. From what I understand, as long as the 'About This Mac' overview recognizes and reads 6 GB (rather than 4) for memory, then the machine can make use of it. I have a couple maintenance and cleaning up tasks to do first, then I'll get the additional RAM. I appreciate your help!
