ScreenConnect on CentOS is sluggish
-
@JaredBusch Cool, if they had it out on that in 6-9 months I'd be thrilled. Our performance has been okay with Mono, but the whole Mono-wrapper thing is an unnecessary bit of overhead. I'm guessing the Linux server will surge forward in speed once they get that working. Hopefully no major roadblocks.

Alright, upped the memory to 4gb for testing and wiped the sessions.db file.
So far only a single high CPU warning right at boot time, so going to expect/accept that.

Session.db changed dramatically.

Question on that - Do you have the system do DB maintenance?

It wasn't set on the NTG system at first either. But once set, and allowed to cycle it's kept the DB in check. If you set today, it's likely that it won't process until the next run time, which will be Tuesday Night / Wednesday Morning....
At least that is what SC Support explained to me.

I have a clean Session.db, so nothing there now anyway. Debating if I should put the old one back and let this run.
-
ok, just moved the new session DB out and copied the old one back in. going to setup the maintenance task and see what happens.

big ba-da boom

Put the new one back and it start up just fine /sigh
-
Well at least the new one is still okay... would be a major pain otherwise.

A week later, the database file is still small with 157 devices having reported back in.

Worked perfectly this time..

Going to run the DB maintenance on this and see what happens.
You can only choose one thehour inthe drop down, so the next hour is 17:00.
Currently 16:12 here.

Well, that made just a small amount of difference..

Little follow up to this as SC on CentOS was discussed in abother thread.. DB size is still small.
