labview 8 splash screen

I just fired up LV8, and it took over 1 minute to get to the "getting started" screen.  I'm not sure if it did this at day 1, or if it happened more recently.  All my apps are still in 6.1 and 7.1, so have not developed in 8 yet, but I didn't recall it taking this long before...  Not sure...

I do remember trying to cleanup the list of processes in Windows Task Manager, and noticed there were a lot of NI processes in there, so may have shut some down that maybe should be left running to speed up the startup of LV8.  Or alternatively, maybe shutting down some of those resident ones would help speed up the launch.  (There are at least 3 that start with "ni" and at least 3 that start with "lk".)

another thought: Maybe it is looking for a TCPIP server.  Can you change a setting to make it NOT look for a server?

Mike Neal just posted a detailed analysis of the LV8 startup and causes for possible slowdowns.
 
Read all about it in the following thread:

Im pretty sure what I am seeing is not load times. I am seeing literally a 5 MINUTE delay. It isnt loading anything at the time. No CPU, no hard drive light. Nothing. Just sitting there like its waiting for something. Then all of the sudden it starts to load all the VIs and its fine. That 5 minute delay happens everytime labview 8 is loaded. it does NOT get better with subsequent loads. I think what i am seeing is something different than just overhead. Its clearly waiting for something and times out after 4-5 minutes.

Your situation sounds simlar to what I was seeing on my machine at home.
 
One of Michael suggestions (in the thread linked by Christian Altenbach) was to defrag the hard drive.
 
I have to try this out to see if it helps for my machine. I do know that at about the time I was loading up LV8 on my machine, I was getting pretty low on disk space. This (in my mind eye) lends credability to that theory in that it is very likely my LV8 files are fragmented.
 
The suggestion to shutdown my virus checking durring LV8 load times is alos a good suggestions that I can try at home but not here at work.
 
Composing this reply inspired another thought. How is our disk space?
 
The following may be old news to some and new to others.
 
When I see a Windows type application taking a long time to do something but at the same time the CPU is NOT at 100% then I have to suspect an I/O of some type is taking place and the process is probably in an "IO_Wait" state (Note: My terminology may be wrong for Windows. The last time I chaced OS internals it was VMS).
 
Three likely type of I/O waits that I would suspect are;
 
1) Waiting for the file to be read
 
2) Waiting for virtual memory to be allocated (still disk I/O but initiated by the OS)
 
3) Network I/O
 
Last first. I unplugged my network cable and it did not make a difference.
 
The other two items can be tracked by using the Task manager and adding more statistics to the views. Page Faults, etc.
 
Now for my own sake (I do not know if it helps you) but I seem to remember in one of those virus-check/ Anti-Spyware things giving me the option NOT to check this in specific folders. I may try that as well.
 
So I realize that none of what I have said here helps you right now. I also suspect it will take me weeks to fully investigate all of these possibilities.
 
The only other thing I can say at this time is "If I fugure this out, I will let you know!".
 
If you happen to find something that works for you, please share.

I would think if it were a defragmentation or disk space or memory issue we would see the hard drive light on- which is not the case in my experience. Once the splash screen goes away, the project loads quite quickly.

Pulling the network cable makes no difference.

Im currently un installing. Im going to try a fresh install. Im spending so much time staring at the splash screen that the re-install will be a drop in the bucket time wise.

I just finished the re-install. Clicked on labview 8 in the start menu, and it CRASHED on startup. I tried again, and its taking 5 minutes.

Sure am spending a lot of time watching the splashscreen...

"Sure am spending a lot of time watching the splashscreen... "

I wouldn't mind the load time IFF the Splash screen displays current news headlines, stock quotes, weather.. maybe even some LabVIEW tips while loading!  Smiley Wink

NEWS FLASH!!!!!!


I just emptied my user.lib folder and restarted labview. It started INSTANTLY. Wow!!! I can work again!

The only problem is, my projects all rely on my libraries...

Can anyone else whos been having problems test to see if emptying your user.lib (just rename it) solved your startup delays?

Maybe NI can work on a solution if they know this is the problem....

This is interesting... I can placed my libraries back in to user.lib one by one until the splashscreen started to hangon me.

Heres what i found:
    I had placed shortcuts in my user.lib folder linking back to my project folders, and shortcuts in my projects main folders pointing ot the library so that i could nevigate quickly between them when browsing for VI's. When i deleted the shortcuts from the user.lib folder the Labview startup time went from 5 minutes down to under 5 seconds!

I wonder if Labview follows the shortcuts when building the user.lib pallets... Vi's in the shortcuts dont show up in the pallets, but when i deleted the shortcuts to the larger projects the load time got significantly shorter, whereas deleting shortcuts to smaller projects did not reduce the start time much... wierd...

For now im going to move my shortcuts up a folder (in the LabVIEW 8.0 folder) because they are very handy for navigation. Hopy my babbling helps someone else.

One more  thing... I use Subversion for source code control, which puts folders called ".svn" in every folder in the project to hold the versioning information. Labview is probably traversing into these folders when building the user.lib pallet, causing longer startup times. Maybe LabVIEW can ignore folders that start with a period AS WELL as an underscore?

Also, of course, supporting Subversion as a source code control utility natively would be SWEET- its open source, its easy to use, and it gives the big guys like source safe a serious run for their money. (nudge nudge NI)
