Creating Kanban is slow

[marshall-2004]

After using it for a week, a new Kanban can not be created immediately. It needs to wait for a few minutes for the forced refresh to succeed. Refresh immediately, Kanban creation failed.
The foreground page is always in the refresh state and no results are returned.

Do you mean creating a new board?

How much RAM Wekan server has? Is it swapping? You see with free -h

[marshall-2004]

Hi As you said, I encountered this problem when I was building a new kanban. The Ram information is: Thanks.

Hi,
you did not add any RAM information.

Wekan is SPA (Single Page Application). That means, when first loading Wekan webpage, you need to wait for Javascript, HTML, and board data to load, and after that you should not reload page, you should use navigation at Wekan. That Javascript contains all the huge amount of features Wekan has, and Wekan really needs all that to load to work, and that loading time is really required, it's not a bug. After loading Wekan usually works fast.

So the question is, after loading Wekan board once, after that, does Wekan work fast?

Hi When I create a new Kanban, I don't have to refresh it. I have to wait about 5 minutes for it to be built. After building, check the Kanban, there is no waiting delay, only when creating a new one. However, when it was used a week ago, there was no such problem. The difference is that during this week's use, there was an increase in data. I recorded the size of the files on the server. Please see the attachment. I found a strange phenomenon I switched to English for the Chinese display of web pages. I found that creating Kanban was normal. I switched Chinese again and found that there was no such problem. I didn't make any adjustments to the server. I'll continue to observe this phenomenon. Thanks.

What webbrowser are you using? What webbrowser version?

What operating system are you using? And operating system version?

How much RAM you have in your computer?

I'll try is really Chinese language selection causing 5 minutes for creating a new board.

Hi I use Chrome browser, the browser version information is: 86.0.4240.198 I use win10 professional 64 bit operating system, memory is 8g. I don't think it has anything to do with my browser and PC, because I tested it on Mac Book air, and the same problem will happen. This phenomenon has now disappeared, and I will continue to observe the test. Thank you for your support.

In Wekan, using webbrowser and Chinese in Wekan, try:

1. Right click webpage / Inspect / Console
2. Copy all text from there (could be errors etc) to your reply, if there is any text.

You could try clear browser history or cache, like images, etc temporary files, and close extra tabs if you have many tabs open. There is no need to remove cookies. Maybe that browser history slows down browser?

[marshall-2004]

Hi I just tested again, but the problem appeared again. It has nothing to do with the change of pronunciation. I changed it to English, and the problem is still the same. I cleaned up the browser cache and the problem remains.

How many boards you have at All Boards page?

In my own Wekan, I have about 300 boards. Opening All Boards page takes 3 seconds. Creating new board takes 2 seconds.

I am running Wekan server on my computer that has SSD disk.

[marshall-2004]

Hello, my wekan server is running on ordinary SCSI disk. I'll try a virtual machine migration. The number of Kanban I tested is only a few, and the total number of Kanban may be about 300.

[xet7]

There is huge speed difference between SSD disk and normal SCSI disk. SSD is much faster.

[marshall-2004]

OK, I migrate to a better disk for testing. It may be a disk problem.

[marshall-2004]

Hello, it's really a disk problem. I migrated the virtual machine and used a better disk. There is no such problem. Thank you for your support.

[marshall-2004]

I'm sorry. Today, after I moved the virtual machine to a good disk, there was no problem. I waited for a few hours to test and found that there was a similar problem again.Now the server is an SSD hard disk. Is server deployment supported on esxi virtual machines? Thanks.

[xet7]

@marshall-2004

I currently use bare metal servers for Wekan installs. I have not used esxi. Virtualization is slower than bare metal.

[niconori]

We use wekan-Snap on esxi with netappstorage (hybrid aggregate with sas and ssd drives) and it runs verry smoooth like forever. Dont think that this is your Problem.

[xet7]

It would be nice if someone could do performance profiling on Wekan, about what part is slow, and maybe even provide pull requests for fixes. For example, if Wekan loads too much data at once, limit amount of data requested, etc. Or add/remove indexes. I don't yet have ideas about what part of Wekan is slow.

[marshall-2004]

Hello, after these days of testing, Kanban tools still occasionally get stuck when creating kanban. I migrated the common folder to other physical machines for testing, and found that two machines would be stuck at the same time point. In other words, when there is a problem in creating Kanban cards in the virtual machine system, there will be problems with the physical machine. I can send the common file to you. Will you do the verification test? Thanks.

[xet7]

@marshall-2004

Yes I can do verification test.

For sending securely, I recommend you create free email account to https://protonmail.com that does automatically encrypt email and attachments to [email protected] , that is my support address at Protonmail.

Because max file size per email is 25 MB, here is how to create attachments in 20 MB pieces:

sudo su

cd /var/snap/wekan

sudo apt install p7zip-full

sudo snap stop wekan

7z -v20m a common.7z common/

sudo snap start wekan

And then send those common*.7z files at /var/snap/wekan/ with Protonmail email to [email protected]

Ok it seems that feature Admin Panel / Global Webhooks makes creating new board very slow. That Global Webhooks feature sends all boards actions to some URL. I will think would it be possible to make that feature faster. When Global Webhook is removed, creating new board works fast.
