is there any suggestion how i solve this problem? i cant install background worker since our hosting not provided it. thanks for your help

I wouldn’t be surprised if Group_Assign is slowing down your interaction on the board, to some degree. I doubt it is your only culprit though. Improvements have been implemented in the past, to help reduce queries, but its a beefy plugin, and kinda is what it is. I have never really noticed a difference on my test machines though, so how much it would affect your speed, I couldn’t tell you.

If you can do without some of your plugins, look towards the ones that are modifying the board or interacting with the database regularly, i.e. Group_assign, Customizer, BigBoard, Boardcustomizer…

You could simply, turn off every plugin, and see if your speed comes back, then start activating them one by one to see which ones are really affecting your speed.

Not sure how much they are affecting you, it could just simply be your machine/server limitations. I’ve seen complaints about speed of Kanboard without plugins before, so, it’s possible the plugins themselves really aren’t the main reason, could be disk i/o.

Your DB version is also behind, there are new releases…something else to consider.

Probably not a major reason, but your linux kernel is quite old as well. I feel like mine is old at 4.14.

Another factor, you say 5 projects, 5-6 tasks each, but how many projects from the past that are closed…those add up. Could maybe try purging those old ones, back them up somewhere else if you need them for records.

hi creecros. thanks for your reply. ill try to find which plugin affect this delay. coz i remember when we first use the kanboard with projects and without plugin its very responsive.

at first its feel slower when we set all user got all notification in email. its resolved when we changed smtp to mail.

in the meantime, would you help determine which plugin producing this query?
