Delayed line drawing/slow JOSM

[jumat@…]

Bei der aktuellen/neuesten Version von JOSM ist mir aufgefallen, dass das Zeichnen von Linien mit deutlich wahrnehmbarer Verzögerung zwischen Punkt zu Punkt erfolgt. Klicke ich in die Karte um einen Node zu erstellen, ziehe dann die Maus weiter, bemerke ich leider deutlich, wie verzögert der Cursor dann den Mausbewegungen folgt.
Das ganze wird umso schlimmer, wie mehr (neue) Nodes ich gesetzt habe bzw. je mehr Daten in der Datenebene liegen.

In the newest version of JOSM I recognized, that drawing lines is delay recognizable between point to point. If I click into the map to create a node and move the mouse I see very obvious the delayed mouse movement following of the cursor.

The whole gets worse the more (new) points I did set or the more data is in the data layer.

English please

Can you please disable "New_basic_style_for_JOSM" and tell us if it improves the situation?

[jumat@…]

I have disabled this style, but it does not improve the situation unfortunenatly.
When working with JOSM for more than 30min, it becomes slower and slower. The delay between one click, mouse moving and the other click is around 1sec in the meantime.
With previous version this issue don't occur so strong.

[Don-vip]

You're running out of memory, see Download#Outofmemory and Help/CommandLineOptions#Javaoptions how to increase the memory allocated to JOSM.

[jumat@…]

Ok, thanks for notice.
I have checked this sites. But where do I have to add the command lines "-Xmx..."? Can you explain this in detail?

[jumat@…]

BTW: how many MB or GB should I reserve for Java/JOSM? What is your recommendation to get the programme working fine?

[Don-vip]

2 GB is a minimum to work correctly. You can set up to 3 or 4 GB if you're working on large datasets.

[jumat@…]

I have increased RAM usage to 3072MB, so 3GB.
I've done this at: Preferences > Java > Java Control Panel > Java > View... and in the column "Runtime parameter" I've added "-Xmx3072m.
Is that correct?

[Klumbumbus]

You can check how much memory is assigned to JOSM via Help -> show status report -> Memory Usage:

[jumat@…]

Ok, I have checked this, see below:

No you still have the default amount of memory:
Memory Usage: 644 MB / 910 MB (356 MB allocated, but free
It means 1 Gb is allocated to JOSM and you have only 356 Mb of free memory. That's not enough and probably the cause of your performance issue.

[jumat@…]

Yes, but obviously I my trail in the java settings has no effect on the memory.
How can I this on a Mac computer? This description linked above does not help me in fact, beacause I do not know where I have to add this suffix -Xmx2048m or similar.

[Don-vip]

For the macOS package I guess you must change the default value in Info.plist file?
It is set at <string>-Xmx1024m</string> we should probably increase it. It was defined a long time ago when computers had less memory.
I don't know how macOS works, if the file is copied somewhere in your user directory, or if a shortcut is created.

[anonymous]

Thanks for this note. I could increase the memory to 3 GB. I hope, this will solve the problem. So I will observe it and keep you updated.

In 13722/josm:

see #16260, see #16311 - increase default memory options to 2GB

[jumat@…]

Do you mean the Version number by 13722?
I have increase memory in the file Info.plist, exaclty as you have written above. Do I have to change other string?

[friedl]

Same problem here. After each node it takes about a second (or even more) until I can continue editing. Therefore this version is not useable for me.

@friedl: From what version were you upgrading? Can you please share a session file where you notice the performance problem?

[friedl]

I've fixed the problem on my computer:
It seems that one of the plugins (or the chached data of a plugin) caused the problem when using a newer version of JOSM.
There was no problem when using josm-snapshot-13629, but with josm-snapshot-13640 I had the performance problems.
After unsinstalling all plugins and then reinstalling the plugins the problem is gone.

Since I have a backup of the enitire JOSM installation I will try to find out which of the plugins caused the problems.

[friedl]

I'm not sure anymore if the problem has anything to do with the plugins. The problem gets solved after opening the settings (without changing anyhing but saving the settings) and restarting JOSM a few times.

Note: I'm using a portabel version of JOSM using this script to start JOSM:

set APPDATA=.\PortableApps\JavaPortableLauncher\Data\AppData
.\PortableApps\CommonFiles\Java64\bin\java.exe -Xmx3G -jar .\Josm\josm-tested.jar
rmdir /s /q %LOCALAPPDATA%\JOSM

[Don-vip]

Hum that's very strange. And I can't find anything in the recent changes that could cause such a major performance hit.

[jumat@…]

I have also tried to uninstall all activated plug-ins. But, there is no change at all.
If I use the JOSM in another country (usually I'am mapping in Austria, but sometimes also in HUN and SLO) it's even lower than in Austria. Hungarian mapping is really tough, because the delay is nearly 2 seconds!

[Don-vip]

Same question, can you please share a session file where you notice the performance problem?

[jumat@…]

Where is this file located in detail? Name?

[Klumbumbus]

You should reproduce the problem and then click on File -> Save session as...

This saves all your current layers in one file. Attach the file here so we might be able to reproduce the problem.

[friedl]

I found out that the problem reoccurs on my computer if I delete the file "%LOCALAPPDATA%\JOSM\cache\left-right-hand-traffic.osm".
Deleteing any other file (or all other files and subdirectories) in the cache directory does not influence the behaviour.

[Don-vip]

Replying to friedl:

the problem reoccurs on my computer if I delete the file "%LOCALAPPDATA%\JOSM\cache\left-right-hand-traffic.osm".

Thanks! I can reproduce the problem and confirms it occurs the first time JOSM is launched after deleting the file.

[Don-vip]

First problems found. The operations performed to optimize the left-right-hand-traffic dataset create a LOT of commands which stay in the command stack dialog even after the deletion of the temporary dataset:

This causes a massive CPU usage to refresh the command stack tree each time a new command is added (in draw mode, after every click):

[jumat@…]

Can you solve this problem/issue with the next update?

[Don-vip]

Sure.

[Don-vip]

In 13729/josm:

fix #16260 - fix major performance problems seen during first JOSM launch:

• new API to notify about undo/redo changes
• use this API in Command Stack dialog to alter lightly the undo/redo trees instead of rebuilding them entirely at each command (very costly operation for large trees)
• purge the command stack after computing the left/right traffic data to avoid starting JOSM with already many thousands nodes in undo/redo trees
• avoid memory leak with JoinAreasAction when computing the left/right traffic data

[Don-vip]

In 13736/josm:

see #16260 - fix build

[Don-vip]

In 13739/josm:

see #16260 - fix spotbugs serialization warnings

[anonymous]

I have now uploaded the requested, exported file (session save aa..), when JOSM became working slowly.

[jumat@…]

I have now started JOSM and edited approx. 150 objects. I observed, that the cooling of my mac is working intensively, so I think, the CPU-load is high. Just JOSM is opened/active (and Google Chrome). The delayed line drawing is visible.

[Don-vip]

Did you update JOSM?

[jumat@…]

I'am using latest stable JOSM-Version 13710, which is shown on the starting page of JOSM. Where can I get the latest version?

[Don-vip]

Here: josm-latest.jar

[jumat@…]

In the meantime I have installed latest JOSM Version (13878) and the problem with line drawing occurs again. Namely, after the first upload of data to OSM-server as I have observed.
e.g. I draw lines, points etc. and do tagging. Usally after 500-1000 points I do an upload to OSM into a new changeset. After this step, JOSM becomes working slowly and the problem with delayed lines occurs again.
Before upload, my settings in JOSM are set to check properties of adresses, streets etc. (Settings > OSM data checker > property rules).

[jumat@…]

I would like to make the notification, that this issue (delayed line drawing/slow JOSM) is currently discussed in Austrian subforum of openstreetmap.org. (​Post 130 onwards).
It occurs on various platforms (Mac, Linux, Windows), so it really seems to be a problem in JOSM/Java using resources of the computer.
