Help improving performance

[bryandoyle]

I have an older internet switch.....maybe that is the issue?

In addition to CPU, look at Disk and Network.
Recording and watching recordings are both Disk and Network intensive.
Comskip is CPU and Disk intensive.
Daily guide updates are CPU and Disk intensive.

Both Disk and Network look ok.

I am getting buffering without any com skip running.

I am starting to think I have a bad drive…..I tried copying from it and the copy is running very slow.

@bryandoyle

I am having a buffer issue. Any ideas.....I don't see anything in activity monitor.

I believe the 1 client is the DVR trying to record to disk and the disk can't keep up with the source stream.

Thanks….what do you mean by ‘1 client’?

I am going to swap out to another drive.

And here's one where it was the network switch.

Can't Solve Constant Buffering Issues

Running Channels on my Synology DS216Play with recently upgraded 8GB WD NAS drives. It will work great for awhile (days) then suddenly bog down with unwatchable buffering. Doesn't matter if I'm watching live or a recording. Though I have a 4 channel HDHomerun, I only record a handful of shows so would rarely have more than one recording at a time. My log shows there was a show successfully recorded about midnight last night and the commercials identified. Six hours later I woke up to watch the n…

Another one, disk related

What are these Errors?

I got the logs. It doesn't appear that the DVR crashed at all. That message that you saw was harmless. I did notice that you had a number of log messages that looked like this: 2020/02/28 01:00:08.330788 [WRN] Buffer for 131AEEA1 ch1250 is more than 99% full (clients=1, len=33219788) for recordings around that time. It appears the only thing "watching" that channel was a recording, which would indicate that your disk is unable to keep up with how much you are trying to record. So, your disk …

Thanks for all this….trying new disk soon and probably updating network switch.

My gut says disk is going bad. Everything has been working well with no other changes.

Since you are are wanting to use a drive that is going to get a lot of usage and maybe constant usage you might want to consider looking at a NAS grade drive. Yes, it's going to be more expensive but should be better for your use case. honesty if you find our current drive to be bad, you prob can buy an internal NAS HDD and install it in the current WD enclosure. if you are that savvy that is.

Thanks for everyone’s help here…..it was definitely a drive that was was having some performance issues….perhaps failing. Upgraded the drive and r/w speed and buffering and all other issues are gone….also turning off spotlight helps.
