Set windows service priority c#

Can you clarify what you mean? Question is if AV software could be slowed down by controling process which have priority below normal. All these processes are chcecked by AV software, AV software check what they do which file are they handling and so on.

But AV works with High priority. Could happend that AV software with High priority is controlling process whith low priority and because of controlled process with low priority working slow, AV software is also slowed down.

Thanks a lot for your view. Process priority is not specific to these processes, so any difference that there may be would be felt anytime this type of scenario would arise. The behavior or experience in general may vary from AV package to AV package. If a performance concern did present itself, of course one could revert any changes to see if they in fact played a role.

Indeed the issue that prompted this article is itself a performance concern, so one may, in that scenario, need to choose between the lesser of two evils Post a Comment. Experimental - let me know how this works! More possible 0x8ddd fixes. Another 0x8ddd fix? Yet another potential fix for 0x8ddd? My 0x8ddd Experience. Part 1 Part 2 Part 3. My Green Paste, Inc. The thread has reached a final state, such as Aborted. The value specified for a set operation is not a valid ThreadPriority value.

The following example shows the result of changing the priority of a thread. Three threads are created, the priority of one thread is set to ThreadPriority. BelowNormal , and the priority of a second is set to ThreadPriority. Each thread increments a variable in a while loop and runs for a set time. A thread can be assigned any one of the following priority ThreadPriority values:.

Skip to main content. Just hobby code I'm fiddling with, thought somebody here might have made a service in C before.. Take a look in your event log. Event log just said it timed out. Not sure what I did partly because I was accidently testing an old version for a few compiles, doh! Could the query be narrowed? You can do some really nasty crap but really I would go with the WMI stuff. If you're asking these sorts of questions you definitely shouldn't be doing the hooking of system calls, and it's dodgy whether or not you want to do what you're doing anyway.

Can you not set the IO priority of the process doing the transfer lower? That is surely the desired behavior. Also look at using the Background Intelligent Transfer service instead. The other thing is that the nasty crap that you do and can get to work while you're debugging as a user, potentially even an admin may not work when you drop back to running with the local system account privs.

If you're looking to throttle the amount of bandwidth that your background process uses, are you already using a ThrottledStream implementation? Lowering the process priority is possibly not the best proxy for making your intent clear to the system. Interesting read shuggycouk, but yea I'm not looking for anything like kernel hooking, you'd probably risk bumping up against Kernel Patch Guard since I'm running x I just wanted the best legit way. The program actually does drop priorities of the transfer program, by which I meant robocopy, not network transfers, in addition to raising priorities of more performance critical apps.

I suggest learning how to use BITS. You learn more useful stuff. But by all means have fun with the original plan. WMI will almost certainly be your best bet, for all its ills it's pretty language agnostic. I've played with BITS in the past, using powershell.

It's a neat concept, but my issues are with local machine traffic, robocopy-ing from say my D : to my F: drive, while watching high bit-rate Blu-ray backups movies from D :, will result in stuttering without priority adjustments.

I think it just introduces pauses between each - I tried it locally and it slowed it down a ton? Obviously that's not as nice as dynamically throttling the copy as required for other activity. But you could always just do that via a batch script.
