XF 1.2 [SOLVE] Addon installation take too long time



I have migrate my forum in a new dedicated server (i3 / 16gb/ssd) on a fresh debian installation, since, addon/extension installation take too long time (usually more 1 hours ! )

The admin.php?tools/run-deferred run good but i don't know why so long.

I don't have any errors in the server log and also don't have a lot of extensions.

What do you think about that?

What steps are taking long? (What text is it showing specifically? The number of "." at the end of specific steps is relevant.)

Generally, this simply indicates that your disk write speed is really bad. There will be some CPU dependency, but disk writes are the most significant here. This can be tuned in MySQL or even with some /etc/fstab changes (but that's much more fundamental).
