Modeller responsivness really slow and lagging when selecting, moving items

I have been having this issue for some time now (even on the latest 3.2.6.094 64bit version). As I am documenting a process I would sometime need to re-organise the direction of the process flows, which often involves multiple selecting items and moving and aligning.

What has been plaguing this app for me is that sometimes the process is incredibly slow. Anyone can easily replicate this issue:

- Start with a blank model,

- Create 10 linked tasks in different places,

- Select them all,

- Press align horizontally,

- Press align vertically

Expect this last action to take around 40 seconds to complete. It also doesn't matter if it's vertically first then horizontally after, this is just an example to get the modeler to change a number of items at once - that amplifies the fact that it's quite slow per item in general.

If (let's assume) you performed the above steps and the align vertically was pressed by mistake, the undo function takes just as long.. I do not think that a time interval of nearly a minute and a half (+40 sec and + 40sec) in case of a mistaken button press is acceptable.

As for specs, I think these are more than enough:

OS Name Microsoft Windows 10 Enterprise

Version 10.0.16299 Build 16299

System Model HP EliteBook 840 G3

System Type x64-based PC

Processor Intel(R) Core(TM) i5-6200U CPU @ 2.30GHz, 2400 Mhz, 2 Core(s), 4 Logical Processor(s)

Installed Physical Memory (RAM) 8.00 GB

Any suggestion on how to solve this issue would be helpful.

I need to know something about this soon please. Our company works with Bizagi and I need to work in a process right now, but the speed to move flows and other elements does not allow me to do almost anything. This happens since the last update I installed. I do not understand why but I have not found a solution on the web or on their own site that allows me to solve this. Please indicate if it is an issue that is still under investigation or in a phase close to delivering a certain type of solution for users. I understand that the software is free but I also believe that it does not imply that this type of error occurs. I have been working with bizagi since I was in college and before that I thought I was a great process modeler. After modeling issues were added, it seems to me that the BPMN approach that was previously available was lost and delivered a simple but powerful tool to document all kinds of processes.

I leave my personal mail please to keep me up to date if they manage to find an answer or solution or simply to return to the last previous version of the program that did not have this type of error.

I am very attentive to your comments.

I await your answers

Dear Kevin and Miguel,

We have improved the performance of the modeler. Please proceed to download our latest installer which includes some FIXES including this one. Version 3.2.6.098: https://bizagi.sharefile.com/d-s4a475fce8cd4fd78

Juan,

Thank you for your reply and assistance. I have installed the modeller version as you instructed and tested it out.

Quite rightly, Aligning is now very responsive and quick (hooray!). Unfortunately, the underlying performance issue where manipulating objects on the canvas sometimes makes the application unresponsive is still there.

Within version 3.2.6.098, you may replicate the issue which persists on other actions, such as:

- On a blank model, create 10 tasks all linked to each other,

- Align vertically,

- Select all 10 tasks

- Drag items to new location

Result is that the modeller will become unresponsive for around 40 seconds. I have noticed that after this, if you drag the items again, there is no such delay. The issue seems to occur on the next action exactly after an align or distribute action.

Please let me know if I can be of further assistance.

Hello Juan,

Thank you for your assistance and information regarding the fix. I have installed the version you mentioned and can confirm that in fact align and distribute buttons work well.

The issue with slow responsiveness is still present though through other actions.. In my original e-mail I mentioned the align action to illustrate the issue, however the scope of the issue is wider than just the align actions. In the latest 3.2.6.098 version for instance I noticed that in the same scenario as in the OP (i.e. create 10 processes) the first item movement following an align or distribute results in the same unresponsive UI as before. i.e.

- on a blank model, create 10 processes,

- select them all, align or distribute on any axis,

- with the items all selected, drag them in any distance in any direction.

Result is the same 40-50 second wait of unresponsive UI.

I hope this helps to stamp out any usability issues that other users seem to also be having. Let me know if there's anything I can help with.

Regards,

Kevin

I can confirm on Kevin.

Same situation here.

Tried different old versions -still the same.

My system:

i5-6200U 2.4GHZ

AMD Radeon M430 2GB

4GB RAM.

Blank new process tab (non-other tabs) + 10-20 elements. Allign/draging/copy paste lags veery much.

PC power settings forced to maximum performance (minimum processor state 100 percent, priority set to High in task manager) - lag is still preset.

Bom dia,

Desde que atualizei a versão mais recente do bizagi (semana passada - Maio 2018), o mesmo está tremendamente lento. Todas as vezes que vou mover ou deletar uma seta o sistema fica rodando e demora demais para responder. Causa desconforto no manuseio pois estou atualizando na frente do usuário e a ferramenta se tornou lenta demais na resposta.

Alguém pode me auxiliar no problema?

Grata,

Izabel Nascimento

Is there any update on this? I am on the latest version (3.2.7.242 64bit) and the response is horrible when selecting any artifact in a flow to edit or move. Please don't ask for step! Create a diagram, create a simple flow, select an artifact to edit.

Dear All,

Although you have a fast machine with excellent technical characteristics, you may experience these performance and visualization problems because you are using a 4K monitor or maybe the resolution of your screen is not appropriate for Bizagi Modeler.

Please verify your screen resolution and change until you find the one which accomplishes the expected behavior. Thanks for your understanding.

Best regards.

Dear Andres,

May I assume that you have actually bothered to replicate the issue described above on higher resolution screens then successfully cleared the issue by lowering the screen resolution? If so, can you please inform us what resolution worked for you?

Also, as per https://help.bizagi.com/process-modeler/en/index.html?bm_requirements.htm, the minimum supported resolutions mentioned are 1280x720 *or higher*.

I am still failing to see what an apparent bug that manifests immediately after aligning a group of icons (see http://feedback.bizagi.com/en/topic/modeller-responsivness-really-slow-and-lagging-when-selecting-moving-items#comment-5610) has absolutely anything to do with screen resolution.

Concordo plenamente com o Kevin.

esse tipo de resposta demonstra que a simulação não foi estressada ao extremo. No passado tive problemas com consumo de memória pois costumava usar as teclas de seta direcional para movimentar os elementos e com isso o bizagi cria um "desfazer" para cada movimento, chegando a consumir gigas de memória da maquina em um simples fluxo. mandei o arquivo, expliquei no detalhe e nunca obtive uma solução conveniente para o problema, quando percebo que vou ter que fazer muitos movimentos nos elementos tenho que perder a precisão e usar o mouse.

Resumindo, lentidão no manuseio dos elementos de um diagrama é um problema crítico com a plataforma.

Hello,

Lag during manipulating objects is still present - with any objects, e.g. task, object, etc. It's freezing for a long time.

Bizagi version: 3.4.0.062.

System: Windows 10 Version 1803 x64 (KB4493437).

Processor: Intel Core i7-7700HQ 2.80 GHz.

RAM: 16 GB

Graphic card: NVIDIA GeForce GTX 1060 Max-Q Design.

Any help would be appreciated. Changing high resolution DPI between System, System (upgraded), and Application doesn't help. It's a nice software overall, but it would be a pity to change, because now it's unbearable.

Best regards!
