Thanks to all. My objective was to find the source of my slow early 09 IMac. I deleted old large files which helped and I'm planning to up from 2 to 6 or 8 GB based on your collective comments/advice.
Re: "cabled connection": I have the Comcast modem connected to my new Airport Time Capsule. The desktop, and assorted other OS and IOS devices are users via wifi. This config works but would connecting the desktop to the Time Capsule (or other config) improve the speed of the IMac?
If you had provided that 2GB memory information earlier could have replied better. Poor thing is being throttled. Also how much free space is available on the hard drive and total capacity?
- yep, would have helped from the beginning to know the specs on your computer; also, please provide which OS X is installed - if you have upgraded to one of the most recent operating systems, 2 GB of RAM is like driving your car w/ two holes in the floor for your feet to reach the ground; e.g. Apple claims that 2 GB is adequate to run Yosemite but twice that if not even 8 GB (which is on my MBPro) is recommended. SO, indeed, add more memory - OWC
(Other World Computing) is a good source of purchasing more RAM.
In addition, concerning you cabled connection, the Comcast signal coming into your modem is likely going to be your 'bottleneck' (as explained in my post) for your internet speed - as a check, simply plug your iMac into ethernet and use Speed Test
to check your DL/UL speeds, then bring your laptop on Wi-Fi next to the router and check its speeds - both will likely be similar and probably lower than you expect. My older generation AirPort Extreme router on 802.11n is transmitting a signal to my laptop (next to the router) of 240+ Mbps, although when I run a speed test, I'm still getting only 20 Mbps (now that is Time Warner's lousy cable service into my home).
