Hello everyone!
I am new on ubuntu 20.04.
I have a server that runs ubuntu 20.04, we have a web application installed on. But two of their features take a lot of times to complete. However, they were running well since few weeks.
Please, could someone come in help?
What changed? Are you certain that nothing with the application changed? Or what about the network? Or the client connecting to the server? If you can eliminate all of those possibilities, then it might be something to do with the base server. You could look at your apt logs and see what has been updated and you might be able to figure out what the culprit is. There will probably be a fair amount to wade through, so that’s not going to be easy. For those reasons, I’d start with assuming the server is not the issue.
I checked the log, there are some automatic upgrades related to: docker, libpython3.8, libfreetype6, libfstrm0, etc.
Removed: lunix-modules-5.15.0-130-generic, lunix-header-5.15.0-130-generic, lunix-hwe-5.15.0-130-generic, etc.
Do you think any of these changes could affected the speed of the web app service? Thank you for your help
Any involved application could be related. Figuring out which one isn’t going to be easy.
How are you measuring this slowness?
The problem is that when a user performs certain tasks within these two features, the requested page always takes at least 15 minutes to load. And a week before that, it wouldn’t happen.
How long did it take then?
Did you look at the logs both for the application and the server? Where is it getting stuck?
have you run top while the web app is being used? any process using 100% cpu, or much greater than anything else, might be a suspect.
