Toad for Oracle version 12 startup very slow


I’m running TOAD for Oracle version 12.12 on a Windows 10 VM.

The Windows 10 is 64bit, the Oracle client is 64bit and I’m running the 64 bit version of TOAD. TOAD is very slow to launch/startup. I don’t automatically connect to any databases, I’m referring to the time it takes from double clicking the Toad for Oracle icon on the desktop to when the list of database connections are presented. I recently worked on a different VM that had a older version of TOAD installed (version 11 something) and the startup time was much shorter which made me realize that the issue I’m facing appears to be version specific.

I was going to upgrade to version 13 and saw another thread in this forum where someone indicated that 13 was slower than 12 (

I set DEBUG=1 in the toad.ini file, and below is the output of the ToadDebug.txt file. I double clicked the Toad icon at 12:04:00. Notice that the debug log doesn’t show anything until 12:05:06 and it finally came to the point where I can select a database to connect to at 12:05:40.

I’ve worked with TOAD support on this before and we checked the usual suspects, McAfee, etc., and none of that was the problem. I’m hoping that someone here can help me figure out what might be going on.

Hi Abe,

It looks like the majority of time is in refreshing the client files. In this process, Toad is simply copying key files from its installation folder to your local user files folder (listed in “AppData Location” in your debug file). My first set of questions would be:

  1. Do you still have a previous version of Toad installed on the same machine that you can try the same startup process?
  2. If so, does that version also start up slowly?
    Internally, we have noticed situations in which Windows 10’s file copy ability is significantly slower than it was in previous versions of Windows. Other people have reported similar problems online (Google “copy file slow windows 10”). There are, of course, lots of proposed solutions out there; but perhaps something from the following Microsoft pages may help in your situation:


If they don’t, you can also try to reset your user files in Toad to a clean set by selecting “Utilities -> Copy User Settings -> Reset to a clean set of user files from the base installation”.

Let us know if it continues to be a problem.




I’m still experiencing this problem. I’ve upgraded to version and I’ve reset the user files per your suggestion but TOAD is still very slow to launch.

I don’t have older versions of TOAD running on Windows 10. I have v12.5.1.1 on a Windows 7 VM and it launches quickly on that VM. I also have v12.11.0.95 on another Windows 7 VM and it is slow to startup. All VMs are configured with the same amount of memory, CPU and diskspace.

I believe it was sometime after I upgraded from v12.5.1.1 that I started to notice a slowdown when launching TOAD and it has gotten worse with later versions.

Are you not experiencing the same problem internally when launching TOAD on Windows 7 or Windows 10 VMs?



Hi Abe,
I am also facing the same issue for a while.
What I have found using Procmon is that most of the time in TOAD startup is spent in writing to a “.tmp” file in the AppData\Local\Temp folder. Quite a bit of time is also spent opening and closing sechost.dll file.

In my case opening TOAD took 10.3 secs out of which 7.2 secs was spent writing to the tmp file and .8 secs was spent in sechost.dll.

I have reset my User Files but still TOAD is very slow to open.
I have If Quest provides me PDB files then I can share the stack trace where all the activity is happening and this issue can be resolved more quickly.

Abe… if you need help using Procmon please let me know. Most likely you have the same issue as I do.


You can probably look at that TMP file with notepad to see what’s in it. Let me know and I’ll see if there is something I can do to speed that up.

We don’t use PDB files, I don’t have any to offer.
