It takes a long time to load sonar filled with VSTi instruments.    Generally, that's probably not Sonar's fault ... however
 
would it be feasible to NOT show the name of every single instrument as it is loaded?     On my system, it's all Kontakt, and there are approximately 5 x 16 x 40 = 3200 instruments loaded (kontakt .nki files, organized in kontakt .nkb banks).   While the names flash by very quickly, still that's a lot of display output for no benefit at all -- they go by too fast to read easily, but it takes a long time to put it all on screen.  
 
This might be a Kontakt function about which Sonar has no control - don't know. 
 

I may not have noticed those names but I don't recall seeing them. What I have seen is the loading of samples that go very fast as a rule. Then I may have up 10 instruments in Kontakt nowhere near the number you are loading.  

I imagine loading a few goes so fast you don't even see the screen.   Maybe the way I configure instruments is out of the ordinary -- there tend to be very many lightweight instruments so that articulations can change very frequently depending on the music. 

Besides, if this were improved it would get me more seldom on this forum ... the 5-10 minutes of loading time are too long for making a pot of coffee, so I have to do something. 
 

 All hail the block tool.....

I don't think that showing the Kontakt loading screens in any way slows down the loading of projects. 

The time required to load instruments comes from pulling the samples (probably at least several hundred megabytes) from where they're stored and either a) shuttling them into RAM if you stream from RAM, or b) separating just the attacks and shuttling them into RAM if you stream from hard drive. The display is just running in parallel with the loading process.

And displaying strings is negligible anyway in terms of overall processing time.

Move your most often-used libs to a solid state drive.  Otherwise, be prepared to take a lot of coffee breaks.

As discussed in the IK forum, the new Miroslav 2 library now takes 5-6 minutes to load just the keyswitching versions of the string sections! OUCH! The same project with the old Miroslav library loads in about 10-15 seconds! A deal breaker if you rely on loading and un-loading those librarys on stage.
Maybe we can change the way live performance is done!!! Instead of a 15-20 minute break at the end of a set we could just take a 5 minute break between songs while the next song loads. It could average out for the night for the same amount of time if we're lucky!!! LOL!
