 1056 QCAD (main)RefactoringVery Low Dead and wrong code in RSPlatform.cpp Closed
100%
Task Description

I am considering pushing the following diff:

--- a/src/core/RSPlatform.cpp
+++ b/src/core/RSPlatform.cpp
@@ -205,25 +205,6 @@ int RS::getCpuCores() {
     cores = sysinfo.dwNumberOfProcessors;
 #elif defined(Q_OS_UNIX)
     cores = sysconf( _SC_NPROCESSORS_ONLN );

-    cores = mpctl(MPC_GETNUMSPUS, NULL, NULL);
-#elif defined(Q_OS_IRIX)
-    cores = sysconf( _SC_NPROC_ONLN );
 #endif

(truncated list to manage size)

I see that most of this was put in there as a kind of a note-to-self originally, however _SC_NPROCESSORS_ONLN is implemented by every realistically possible targets anyway, so for all practical purposes, this is dead weight.

A couple of questions remain, though:

  • #ifdef Q_OS_WIN32 should probably be Q_OS_WIN, so as to include win64 as well.
  • Assuming the real purpose for this function is to determine how many parts a particular task is to be split into in the future, if and when QCAD gets the need to split expensive tasks among multiple CPUS, “core” probably shouldn’t be static - CPUs are hot-pluggable today, and while one probably doesn’t do that on a laptop, it’s not unfeasible in, say, a VDI environment.

Thoughts?

Task Description

Loading any larger dxf file takes very long because of this line:

The call to std::locale is very slow. File-loading can be speed up by approximately factor 5 times on my system when replacing it. I just removed that line and instead added the following in DL_Dxf::in so it is changed only once per file:

std::locale oldLocale = std::locale::global(std::locale(”C”)); // use dot in numbers
while (readDxfGroups(fp, creationInterface)) {}
std::locale::global(oldLocale);

 1662 QCAD (main)Performance IssueLow Select > Select Contour: slow for complex drawings Closed
100%
Task Description

Hi!

when working with files containing many not connected elements (non-poly-line elements) a double click can cause a coffee-break easily. The search for connected entities easily takes over 5 minutes on an up to date machine ([email protected]) with files that are pretty standard in size (2 or 3 MB file size ascii dxf). Adding an interruption-method would be suitable (for example by pressing escape).

attached a file with a polyline of 13000 entities and a second file with just everything duplicated. When exploding the polyline and double clicking an element it takes quite a while until all elements are selected. (this is not an extreme example, I had sometimes 10 minutes of waiting with slightly bigger files, accidently double clicking something).

also an improved algorithm for the search would help to speed up the selection. (e.g. divide the area in smaller parts, do the search there, or an option to search only in the visible view port of the document)

Task Description

QCAD Professional
Win7pro Win-Installer
Version: 3.26.4.5 (3.26.4.5)
Internet: QCAD.org
Build Date: Jul 20 2021
Revision: e596276
Qt Version: 5.13.2
Architecture: i386
Compiler: Unknown

Trimming With AX slows down with many text entities.
Seeing the same lagging with D2 on Circle entities.

Also seen on Windows 10 Pro 3.26.4.0
Forum topic: https://qcad.org/rsforum/viewtopic.php?t=8729

Attached files:
TrimAuto_1.dxf ... 11 entities ... trimming instantaneous
TrimAuto_2.dxf ... 11 entities + 1936 LINES ... rather instantaneous
TrimAuto_3.dxf ... 11 entities + 1936 ARCS ... less than 1 second
TrimAuto_4.dxf ... 11 entities + 121 TEXT ... over 3 or 4 seconds
Slower for larger Arc / Circle

The questions here are:
Should AX trim at text entities?
Can this be optional?

Regards,
CVH

2021QCAD (main)Performance IssueVery LowCannot work with big dwg filesAssigned
0%
Task Description

Openning a big file or doing any action in it, takes minutes to load.
Even dragging the scrollbar slightly left or right, takes mintues to redraw the canvas again, which makes QCAD un-usable for professional use.
Is there a way to make QCAD usable, after loading completed:
- Like suppressing edit until user says so,
- or taking snapshots of rendered canvases to another file and use it, as windows uses thumb.db ( for negative latency :P )

PS: I wish I could help a bit, but my hand are tied. I am just a java freak, I am opt to any idea of porting it to java, if she is still alive.

2063QCAD (main)Performance IssueLowBad performance while zooming inside layout block with ...Assigned
0%
2 Task Description

Zooming in and out is lagging to the point of unusable. This is happening in a layout block with the cursor pointing inside geometry with hatches. When the cursor is pointing outside the geometry zooming works as expected.
The attached file has a very simplified testcase that shows this problem almost in the same way as a more complex drawing with multiple layers and hatches.

edit: I also attached the more complex drawing because it is a bit unclear to me where the lagging stops. Outside the viewport or outside the paper.

I just noticed the selection box has the same problem!
