Maybe the slow display of folder contents in Finder, random brief beachballs, and general instability with app crashes will be addressed in this update. But I have a feeling that will start to be sorted in 10.9.4 or so.
Is it a delay of 20-21 seconds when displaying folder contents? (I think this mainly occurs in Open/Save dialogs, but maybe in Finder too.) If so, see here.
 
I completely agree with you here, but about all MBPs have been suffering from lag issues ever since 10.7 at least and Apple never fixed it.

Although Mac OS X improved a lot between 10.0 and 10.6, dropped a lot in 10.7...

This might answer your question.

1. Bertrand Serlet
S.V.P. OS X Engineering
10.4-10.6

2. Craig Federighi
S.V.P. OS X Engineering
10.7-10.9

I applaud 10.9 for [finally] addressing SMB2, multiple displays, OpenGL 4.0+, memory management, and other power user related issues developers have filed since 10.7, it is still a far cry from the OS X installments under Bertrand Serlet. Couple this with iOS engineering focus and Apple's increasing insistence on moving engineers off OS X to iOS development instead of actually hiring more capable engineers, and you might see a pattern.

True, my Macbook has been suffering from lag issues in various situations.

In Mavericks, just after a couple of days the Mac is on (either being used or sleeping), the changing spaces and mission control animations get jerky to the point where I have to restart the computer. I'm using MBP mid-2010 13".
 
Well so far on my Unibody 2009 this has to be the most stable and fluid version of OS X I've used since 10.6.3.

Quite happy now, looking forward to GM.
 
Airmail app solves this problem ;)

But that's what that postage stamp thingy sitting in my Dock is for. No need to pay for something that's not working and is part of the core OS. :p

If Apple can make a super duper mail client for the iPad why can't they get the OS X Mail App working without the need to buy an App?

When you look at rival e-mail clients, you realise how basic the native one is. I still use the native client as my primary as I use Gmail, but I do have an Outlook.com account and I never got it to work properly with the Mail app.

Neither have I and what's baffling is how sublime the iOS version is. At least I have Mac Outlook to handle my Hotmail accounts but it would be nice if Apple cleaned up and fixed the built in Mail app.

I guess I just have the slow Finder problem, but on multiple machines, all of which have fresh installs of 10.9.1. Thanks for the link; there is a link in that link to a possible fix. Hopefully Apple fixes all Finder related slowdowns soon.

iOS uses Exchange which is perfect, with OS X users are forced to try and configure Hotmail/Outlook manually (IMAP). Apple & Microsoft do not make it easy.

Assuming your problem has the same cause, the simplest fix is to switch to DNS servers that don't hijack (which is a good idea anyway). I mentioned Google Public DNS, but if you're using your ISP's DNS servers and want to continue doing so, they may have a way to opt out of their "domain helper" (or whatever they call it). I think some ISPs' opt-outs work only for HTTP, though, which won't help with this problem.

To verify if you're experiencing the problem I mentioned, ping backups.backupdb and post the result.
 
what else then?

Lots of things, particularly bug fixes. Most OSX point updates are only bug fixes, no new features at all.

Every beta release, someone looks at the release notes and assumes that absolutely nothing is fixed beyond what is listed there.

I don't normally follow these threads but do Apple always release this many betas?

Sometimes. People like to obsess over whether a particular update is too many betas or not enough betas, but there's not much to read into it beyond they ship it when they think it's ready to ship.

I have a MacBook Pro early 2011 - it has been awful with lag in 10.9 betas. The GM was okay, but still lots of lag. The newest beta is working much better for me (not sure if its the beta or the 16g of RAM I just installed - had 4).

ah ok. So 10.10 would be new features but 10.9.2 or 10.9.3 would just be bug fixes?
 
....

Doh ! I know its not Apples style but surely the whole point of a release note is to tell you what they think has been fixed. A good one would even tell you whats not been fixed.

I had 4 gbs of RAM installed on my 2012 MBP, and it was crawling on Maverick. The difference I have seen since installing 16gbs is night and day. I still see a lot of beach balls though, although they only last a few seconds oppose to minutes now.
