Not Responding

There's a current ongoing thread where people are discussing performance problems, which have been an issue all along for people with less than the top-end machines (though even I have the occasional "Not responding" even with a very fast machine. I don't know of any reason why it would suddenly have gotten slower than it was for you a couple of days ago, unless perhaps your Internet connection is compromised temporarily (your ISP having a bad day, or someone else in your household using the bandwidth to download a movie at the same time or something like that). Logos does do a lot of connecting to the Internet for the purposes of Sync. If you set "Use Internet = No" in Program Settings, and restart Logos, it should speed things up somewhat for the time being, but you will have to sync manually every so often (by typing "sync now" command in the command bar), to ensure your user data is backed up.

Here are some other suggestions for improving performance: http://wiki.logos.com/Logos_Running_Slowly

EDIT: BTW, are you on Mac or Windows? Here's another thread where someone reported scrolling has slowed down noticeably in the latest release on Mac: http://community.logos.com/forums/t/32522.aspx

Complex visual filters and an excessive number links between panels are the biggest causes of Logos slow down in my experience. You might want to adjust your layout if you using either of these features.

It's not really a single "glitch" in the program, I'm afraid. Logos is built on top of Microsoft's WPF (Windows Presentation Foundation) which is notoriously slow all around.

It all depends on your point of view.  I believe building an item on a bad foundation is a "single glitch."  If people who have a "super-fast computer" are having performance issues, then the solution for the issue does not lie with users buying faster computers as implied by Bob when he states that L4 was designed for the future.  New computers will only mask the underlying problems.

Logos gambled when they took the risk to develop L4 on a promising but untested development platform.  If you ask me, Logos lost on this gamble.  Not only has WPF has not performed as promised, there are rumors of internal conflict at Microsoft over the future of WPF.  There are issues with .NET3 that are solved with .NET4, but L4 cannot be moved to .NET4 because of there are other issues with .NET4 & L4.

To quote Kenny Rogers, "You've got to know when to hold 'em, Know when to fold 'em, Know when to walk away, Know when to run."

IMHO, it is time for Logos to fold on WPF and to run away from it.  There is no reason to continue to throw away any more good money into this losing situation.

Turning off the internet has transformed the program.

I wonder if a future release will include code to reduce the Internet activity when the program is busy...

Sometimes a reboot of the machine can clear things up. Conflicting software, malware, or a fragmented harddrive are major factors to consider. If Logos is the only program that uses considerable resources that is running slow, then try disabling history via the control panel, unlinking some of the note files if they are linked.

Peace, Lynden!                      *smile*

              Thanks for an excellent post.                 Particularly in giving me the idea of clearing my history now and again!            Perhaps the performance gain is minimal, but a little "tinkering" never hurts, eh?

It's just a question of linguistics. I think the word "glitch" implies a tiny problem easily fixed, whereas we are talking something massive here, even though I agree with you it is a single problem -- the choice of using WPF as a platform. So I would not call it a "glitch."

I agree, and I think they are aware of that.

Since I'd complained and stirred things up yesterday, I thought I should inform you that my Logos 4 is working as normal this morning, I'm even connected to the internet and there are no 'not responding' warnings.

What's changed? I removed a little utility designed to give me an xp like start menu instead of the windows  7 one. I only installed it this week and it wasn't working properly, now it's gone, so are my troubles with Logos 4.

That is very interesting. I'm glad you figured out what was causing the problem in your situation. I wonder if you could tell us what this little utility is, because Logos developers might be able to determine if what this utility is doing to your machine is something common to other programs that other users who are having performance problems with Logos are running.

Logos4 writes lots of updates back to "The Cloud", which I think is at Amazon. Maybe some of the performance issues are to do with some outages at Amazon? Just asking ... I really don't have any facts on any of this, so just asking to see what comments from those better connected ...

sync.logos.com is hosted in Bellingham, not with Amazon. As far as I know the Amazon outage is only affecting ftp.logos.com

I also cannot get onto my User Account page

Hi Rosie,

i am able to get into my User Account page in Logos (i.e. see which books i have in Pre-Pub)

I also cannot get onto my User Account page, so those must be stored on Amazon's server farm as well.

No need to say sorry. That's a great list. Thanks for doing that research!

I added it at http://wiki.logos.com/List_of_known_public_Logos_servers before I read your post.

No Problem [:D], i do that sometimes too.

Would you please add the floating right box of links to your new page when you get can get around to it? (i know its very late where you live)
