Maverick runs slow.. the following solution work for me

Question

Launch Terminal and enter the following command:
sudo nano /etc/auto_master
Enter an admin password when requested, then find the line that says “/net -hosts ….” looking something like this:
/net -hosts -nobrowse,hidefromfinder,nosuid
Use the arrow keys to navigate to the front of that string, and then place a # (pound sign) in front of the / to signify that it has been commented out, it should now look something like this:
#/net -hosts -nobrowse,hidefromfinder,nosuid
The modified /etc/auto_master file should now look like this, the #/net has been highlighted:
Now hit Control+O to save the file, then Control+X to exit out of the nano text editor and return back to the command line.
Now you must flush the automount cache, so type the following command string:
sudo automount -vc
Now you should be good to go, so exit out of Terminal and try to access any Open, Save, or Export dialog box window again. The slowness should be gone completely, and you’ll be back to speedy file interactions through the dialog windows as expected.
This bug has been encountered and reported enough that we can assume a solution from Apple is likely to be due in a future OS X Mavericks update, be it 10.9.1 or otherwise. If you do use this automount workaround, remember to remove the # from the /net entry in auto_mount if and when an official bug fix arrives from Apple.

Thank you.
I am not going to try again with 10049.
I tried using the Install.esd from RecoveryImage folder and it busted my Win10TP partition claiming I did not have enough space to finish. I had 13 GB available at the time, and I had less than that when I did the same thing on 10041before they released
the ISO. 
In the process, I had to remove the dual boot Win10TP partition, recreate a new partition, clean install 10041with the ISO , then upgraded back to 10049.
I had enough  excitement for a while.
One last comment I would like to make......
MS has been warning us about using the beta version and said something like it is only for testing by computer well-versed users.
However, I would like to submit that for every
computer well-versed user, there are 10  who are just "regular" users. Just read the threads in these forums and you have the proof. Most of them do the straight upgrade via WU. Some wouldn't know where to find the ISO or the Install.esd.
We have this Dism /SFC issue since build 9841. SFC in particular is commonly used by all users, more so by "regular" users. Sfc is their basic, and sometimes the only, app to fix things.
MS should have it fixed by now ..... for majority of Win 10 TP users. No excuse they sit on their hands.
