Q: Why is Safari so slow and does not block pop-ups??

OK, I walked through the TextWrangler suggestion and found that my code matched exactly the paste-in Host code, so I just left it as it was.  I also followed the Wacom driver suggestion and deleted my Wacom Tablet driver for good measure.

Bottom line

I seem to see slight improvement, but as I began typing this post I once again was confronted with the bouncing ball and had to wait to continue typing.  On webpages that are long Safari still locks up, but not as bad as it was prior to the driver deletion.  Further webpage testing reveals that pages continue to freeze without getting the bouncing ball.

This all very annoying and am not certain that I have made any real improvements to this problem.  Time will tell, I suppose.

Thanks!

I just shut down Safari and re-launched it while watching the Activity Monitor and was shocked to see that on start-up Safari used 7 GB of ram.  The Safari Networking is using 23.6 MB of ram.  My iMac now has 32GB and wonder how  Safari got by when I only had 8 GB?

After Safari launched its 'Real mem' value is 3.78 GB of ram.  That seems excessive to me since I only have two webpages open, so apparently Safari needs lots of ram to operate with.

@John Galt

Thank you for your post.

I did as you instructed, but could not loan any websites because Safari claimed that I was not on the net when indeed I was when I shut my iMac down.  So I could not load any websites to check Safari's behavior.

I have also downloaded and run EtreCheck and will post those results below.

Thanks again for your help.

Here is the results of the EtreCheck scan.

Just out of curiosity, this is one of the website pages I am having so much trouble with.  It is an iOS keypad tutorial and Activity Monitor shows it to be using 2.27 GB of ram.  This seems excessive to me, but it does have lots of ads.

Thanks!

Sorry for that.  Here is the link I intended to attach earlier.

Thanks!

@John Galt

I restart my iMac holding down CMD-r and found the wireless icon to the right of the flag icon.  It was nearly impossible to see it was so faint, but I did get on the net.  Safari ran flawlessly save for a strange 'translucent' horizontal bar than ran across the web page.  I tested Safari on several pages and it never locked up nor did I see the beach ball.

Now I will go back and read the link you provided earlier.

Thanks again for your help.

Oh, BTW, I turned off the only two Safari extensions that I am using.  This made no difference.

@John Galt

HOLY COW!!  I followed the instructions from the link you provided : If Safari is slow, stops responding, quits unexpectedly, or has other issues - Apple Support.

and Safari is screaming fast now.  Here are the details of what I found in the Library:

---

in Library >

Folder > Internet Plug-Ins

  had a folder entitled Disabled Plug-Ins

  contained one plugin :  QuickTime Plugin.plugin

  and one file :  nsIQTScriptablePlugin.xpt

  I moved all to the trash save for these per the instructions as follows:

  Don't remove Default Browser.plugin,

  nslQTScriptablePlugin.xpt,

  Quartz Composer.webplugin, or

  QuickTime Plugin.plugin.

Folder > Input Methods

  This folder is MT

Folder > Input Managers

  contained one folder :  SIMBL > contained two files:  Info and SIMBL.bundle

  Moved all to trash

Folder > ScriptingAdditions

  Contained two files:  Adobe Unit Types and Adobe Unit Types.osax

  Moved all to trash

---

The only odd thing was that the > Internet Plug-Ins folder had a folder entitled 'Disable Plug-Ins'.

Also in the Library was another similar folder entitled 'Internet Plug-Ins (Disabled)'. This folder contains 1 item: 'Flash Player.plugin'.  I left that as it was.

Must I replace all of these folders to find the 'bad' one?  I probably already know the answer to that.

Thanks again for the link and your help.

@ Eric Root

Thank you for your post.

I have followed the instructions via the following link:  If Safari is slow, stops responding, quits unexpectedly, or has other issues - Apple Support

and as noted earlier, Safari is running flawlessly fast once again.  (I have yet to begin replacing the files to determine which is/are the corrupt one(s).  But while I had the Lib folder open I thought I would follow your instructions as well.  That said, I removed 'Cache.db' to the trash.

Both of my Extensions have been disabled as well.

Thanks again for your help.
