Speed up Cloudron Apps startup? especially wordpress sites

[Supaiku]

It takes a long time for the multiple wordpress sites, and apps in general to get started when cloudron is restarted. The sites are inaccessible for a long time yet server load is low.

Is there any way to speed up the inital startup time?
Why does it take so long?
What factors impact speed the most?

Hello @supaiku
Are you using the @wordpress-managed or @wordpress-developer app?

[Supaiku]

@james both for different sites.

I do have a a lot of them - like 20 or so, but it takes a very long time to startup despite low CPU usage.

There's always all these processes in the D mode - is this perhaps a slow hard drive issue?

This screenshot is even from after they are going, but ususally there are these and then some more explicitly wordpress related processes to match the apache ones.

Check the speed of your storage in MB/s.

In some shared VPS environments this gets low when the server array is overprovisioned.

@Supaiku in addition to your high load average you also have two apport processes at the top of your list. So something has crashed or was killed and ubuntu is currently collecting logs for this.

I killed the apport proceses and that helped the server load and since restarted the server as well, but it seems likely that a failing SSD that I let go way too long is likely the culprit (sdb1 was were most of the apps were stored)...

We'll see once everything is migrated and I try restarting... it's that initial boot up that seems to consistently take forever for the WP sites.
