It's (mostly) snappy once it's started. Which takes something like 5-10 seconds on my PCs. But it keeps previous files in tabs over restart. And with each new geany installation, snappiness deteriorates soon and tabs accumulate until i have a clean up session. Might be an user issue, but this is my primary geany experience.
What are you talking about?
I've never seen that. Many years and many machines.
You've got something weird misconfigured somewhere like a plugin trying to do a failing dns lookup or something.
However I have seen mystery hangs in general, which can happen to almost anything.
I had a machine one time where a self-built version of midnight commander would always hang for several seconds on startup. Never saw that before or since. You can not say "mc takes something like 5-10 seconds to start up" even though it did on that machine that time.
I don't remember the details, but it turned out to be some combination of environment/context ie a particular terminal on a particular client sshing to a particular server where mc itself was, env variables, and/or setting in a mc config file. Might have been something to do with locale or TERM, or.. . I really have no idea anymore.
But the hang was fixed by hunting down the config problem, and I've never seen it before that, nor since.
One of the releases from a few years (or months) back had this issue of slow startup whenever a certain number of files was opened. I experienced this a few months ago while installing the version included in Debian stable.
Following Geany updates fixed the issue, as far as I remember.
If you've got tens of files on an old machine that's probably to be expected. It's efficient with large files, written in C, and on a modern computer could open that many easily. My six year old laptop opens ten files from an encrypted drive in 2ish seconds.
I suppose it could load the interface first, then load the files, then parse and highlight them after the window is up, but don't feel like it would make a lot of difference until its done.
You may find projects useful. Can open the dozen files for one project, then close it, then open the next group from another project. Instead of every file you potentially might want to work on.
