2015.02.05 less responsive
I think the pausing might be proportional to the number of dependent files
when auto reload is on.

Not easily because it has lots of dependencies but the render in short

does it.

That doesn't looks like a Mendel90 part. Could you share that design?

That is curious. I get ca. 5 fps on the full Mendel90 design here.
Which hardware are you using?
Also, you’re comparing to 2013.06 (which is ancient). How does 2014.03 relate to all this?
I don’t see a noticeable difference between the versions.

That would make sense. The auto-reload is checking for any changes and this feature was improved to pick up changes in dependencies too.
The dependency walking apparently takes a bit of time on some systems. We should look into using OS-specific file change notification services as they’re likely a lot faster, at least on systems which offer such services.
Anyway, I’ll have a second look at this in case there’s a bug which causes excessive checking.
Just to clarify: Does turning off Auto-reload resolve all the performance regressions you reported?

Yes, with auto reload turned off the latest version is actually much more
responsive than the old one with the full model loaded.
Older versions are fine with it turned on. The latest I have is
2014.02.25. Do you want me to try 2014.03?
I have never updated from 2013.06 because it does everything I need. My
only desire was concat, but that didn't make it until this last one I
believe.
It seems like it is nothing to do with rendering but something to do with
looking for file changes. It doesn't rattle the disk so the file stats must
all be cached so I don't see why it would be slow.

We did fix a number of automatic reload issues in 2014.03 - I think you initiated the bug reports which led to those fixes.
This was related to burst-writing of files, as well as correctly picking up dependencies.
I’m pretty sure that the performance issues was introduced in that release.
If you could verify that 2014.03 and 2015.02-RC2 behave in the same way for you, that would indeed be very helpful.

PS! In 2015.02 we have some features which may work for you, in addition to concat (and list comprehensions):
o View All in GUI
o Ability to write to camera parameters in the .scad file
o Much faster hull() and minkowski() for common cases
o Much faster 2D pipeline
-Marius
OK I will try 2014.03.
2013.06 does slow down appreciably when the full model is loaded and auto
reload is on but nowhere near as much as 2015, so I hadn't noticed it.

2015.02 reduces the first render time from 20 minutes 27 to 17 minutes 20
second, which is worth having.
The view all seems to shrink the Mendel90 excessively, perhaps because it
is tall and thin.
I noticed the load directory is no longer relative to the file that is
currently loaded. It seemed to get changed by opening a file in another
instance. This is very confusing for me because I have nearly identical
development and release directory structures so I ended up loading the
wrong version and when it takes 17 minutes that is not good. Also it is
hard to spot as there isn't much difference.

Would this be on a Windows system?
I've been bitten in the past by the brain-dead way that MS handles
directory structures. Parent (and grandparent, etc) directories with
large numbers of entries can effect access times for files.
I don't know if they have fixed that recently, but it used to be the
bane of my existence.

Probably not if you are dealing with tens or hundreds of files only and
those files are currently in use or regularly accessed. All the stat data
will be cached in memory. The one exception would be networked file
stores (where generally notifiers don't work anyway).
If you are opening the files to re-check them then depending upon the OS
and the configuration you may well cause disk writes (updating last
accessed times), which if they spin the disk up can add odd delays.
