I am posting this as I figure it might help others who find that SPlat takes ages to load and also have a Malwarebytes Premium sub.
 
For a long time I have found that Sonar takes up to 2 minutes to load (that's before it starts to scan any new plugins). I have taken to just accept and live with it as I tend to load SPlat once and keep it open all day.
 
I have also been a Malwarebytes Premium subscriber for a long time but when I tried to renew recently the renewal failed and I still have an unresolved support call with them so the subscription has now lapsed. 
 
Since the day that the premium sub lapsed suddenly Splat now loads within a few seconds. Malwarebytes Premium includes realtime Exploit, Web, Malware and Ransomware protection so I suspect that this was interfering with SPlat loading.
 
If and when Malwarebytes sort out the subscription renewal I suspect the answer will be to exclude SPlat folders from realtime protection although that does bring a small risk with it. Just a heads up for anyone else who has slow load times.

Yup I posted this yesterday on some thread, maybe you read it.

If you've got startup speed problems.

1) Temporary disable your virus scanner see if that helps.
2) If using hard drives (not SSD) defrag.
3) Check taskman / process explorer for processes that may be taking a lot of CPU when starting Sonar.
4) Check file I/O with process monitor.

Latencymon may give a clue as well.

If you are excluding folders from your virus scanner (I always do this) don't forget to exclude the application and project folders... and where your samples are stored. Also don't forget to exclude processes (such as SONAR.EXE or whatever).

+1 to that.
 
I always do the same and the plug in manager is another one I exclude in AV.
Once they made changes a year or so ago. Many of us started having issues and it turned out to be a reputation scan issue. Meaning the file was new and not logged with anti viruses so it set off a red flag and blew up sonar to crash.
I exclude everything possible.

I exclude processes (Sonar and other DAWs, Melodyne , etc.) as well as folders (Projects, Audio, Melodyne temporary). Most important folders into which new files are written. F.e. with Melodyne (also as ARA in Sonar), that speedup notes detection by a factor of 100 on HDD.  

Yes, this is a given. I would have figured most did this. I have been for many. many years.

Also wait a bit after boot up for things to load and settle down.  A quick look at Task Manager will show you when it's time you can load something serious.  It will also alert you when Malwarebytes, for example, is using the computer and you should go get a cup of coffee first.

I would venture a guess that many weird unsolved PC issues could be attributed to the vast variety of security configurations in use on systems.
 
I have even had cases where turning off real-time protection was not enough to fix my issue, but required a clean uninstall of the faulty security app due to a process or driver continuing to run in the background.
 
I think exclusions for audio program's executables and processes, as well as complete sample drive paths, etc., is the first best step to avoiding any issues in a DAW environment.

Hiya,
 
In MALEWAREBYTES open settings down left and the select the EXCLUSIONS tab.
 
Now ADD Exclusion and then exclude a file or folder, NEXT and then select folder.
 
Now exclude all Cakewalk folders and VST folders. In windows i have excluded the Sonar install folder, the cakewalk folder in Documents & in the hidden programdata folder and the cakewalk folders in program Files / Program files x86. Also my VST folders inc the default steinberg / vst folders in Program files and Program files x86.
 
Maybe REBOOT
 
See if that sorts your issue?
 
Might be worth doingb similar with any other Anti Virus software you have. Look for the exclusions section in that AV software settings.

Nice. If you run the free version of Malwarebytes it does not so real-time scanning so you don't need to exclude anything.

I must be lucky, I don't see any of the general Windows 10 problems others see.  I use the built in Windows Defender and a paid version of Malwarebytes.  Neither affects my PC operations or DAW operations.
