Very slow bash prompt in Rocky 8.4

[kjy5]

I often have to interact with a server running Rocky Linux 8.4 and I noticed recently that after logging in it takes almost a minute for the Oh My Bash prompt to show up. After it does, it behaves normally for a while, but will occasionally get stuck (like it's waiting through a timeout period) before showing the prompt again. This is most noticeable when I run cd to get back to my home directory.

I've replicated this on a fresh install with no addons, themes, or plugins.

Thanks for your help!

Yeah, oh-my-bash (actually the whole oh-my-* project family seemingly is) is very poorly optimised, I actually just bench marked it, you might want to switch to some other plugin manager https://blog.ari-web.xyz/b/comparison-between-the-oh-my-bash-and-baz-plugin-managers-for-gnu-bash/

@TruncatedDinosour So have you identified and solved the reported issue in Rocky 8.4? What was the cause and what is the solution? The delay in the original report is about one minute, but the delay of oh-my-bash in your benchmark is about 0.1 sec, which is different from the reported delay by an order of magnitude. Also, the one-minute delay does not seem to be observed in other environments. So it seems to me that there is a separate issue from the basic design of oh-my-bash as a plugin manager.

Oof wasn't trying to make you angry

Maybe it's from resource usage ? And as oh-my-bash is already quite slow to load, if system load is high it might be sloww on anothner level

Hm, how's your resource usage while it takes long to load ? @kjy5

Also, can you provide me with your bash binary ?

Maybe https://superuser.com/questions/166359/why-is-my-ssh-login-slow is related if you're using ssh, wait let me get a rocky linux vm

How did you recreate it, I'm unable to on rocky 8.4: Rocky Linux 8.4 (Green Obsidian) x86_64

It might be ? I get 1-2s if I compile rust code on the guest

This might be one of the reasons why it slows down Colours are taking a bit too
