NRECORD Process Makes Computer Slow On Cold Boot & Reboot

[BTJustice]

I was trying to figure out why my "System Idle Process" was so high as the hard drive light on my computer is constantly on for about 20+ minutes after a cold boot and a reboot.

I came across this link...

One of the replies said to look a the next process (I assumed sorted by CPU usage).

What was #2? NRECORD.EXE so I ended it by using "Stop NPVR Service" and my hard drive light settled down.

What is NPVR doing after a boot or reboot that requires so many resources for so long of a time? Is it trying to reload the EPG or something?

Why are you complaining if "System Idle Process" has a high cpu percentage? It's supposed to. That's the percentage of time that your CPU is idle, so it will usually sit at 90-99%. When NRecord starts up it does do some basic housekeeping, reloads the recording schedule and sets wakeup requests for every pending recording. This all takes a few seconds. I doubt NRecord is responsible for whatever you think you're seeing.

I know about "System Idle Process". It still seems silly to me there is a process for idleness. You missed the point I was making of it being so high when something was going on.

Anyway it was part of the elimination of what was going on upon booting up. I disabled "NPVR Recording Service" from auto-loading on boot. MUCH BETTER NOW! Now I just go to the NPVR Program Group folder and start it from there. Seems much quicker for whatever reason.

Sounds like pure stupidity to me, Nrecord has things to do when it starts from scratch, like the things johnsonx42 mentioned, checking the database for sanity etc. Stopping it puts your whole system in jeopardy. And for what purpose? Does it bother you that Nrecord does its job?

Windows' sluggishness when cold starting, or rebooting is the reason why I stopped using shutdown. I just hibernate, and reboot it every other week. Anyway, that sort of hdd activity is not normal... have you checked the Nrecord.log after setting down to check if indeed it was NRecord the one responsable (if it was, you should have entries throughout that timeframe)? It could be another process, and disabling NRecord simply freed resources for it.

Not as stupid as your reply. Seriously you ought not reply to posts if it is of no help. The problem is now fixed as I stated earlier.

Good points. All I did was sort the processes by CPU usage. NRECORD was the culprit.

If you're on 7, you can use Performance Monitor rather than Task Manager so get a more detailed look. IIRC you can see "who" is using the disk. Might provide some insight. 20 mins of disk activity sounds high, my machines don't act like that, but then the dedicated HTPC has nothing on it but NPVR.

Post the nrecord.log showing these 20 minutes of disk activity and I'll take a look. A you sure it wasn't recording at time, or updating the EPG?

I disabled "NPVR Recording Service" from auto-loading on boot.

Ok, but dont come complaining when find a recording didnt happen

Do you have any anti-virus software on the server? It might be that the NPRV Recording Service (or one of the sub-processes/threads that it creates like the web server or the MVP/NMT server(s)) is "touching" recording files (to verify they exist or something?) and that is triggering the anti-virus software to do a complete scan of the recording files.
