cpu limiter

[sharp]

I don't really understand how the cpu limiter works? if you can create a tutorial for that that would be great.

- the percentage that I entered is just for one core? What if I have more that one core and I want some thing like "one server will be only using 1 core to run?)

Refers to : "CPU limit (%age of a core):"

- For max percentage isn't suppose to be 100? How doesn't that work?

Refers to : "set between 1 and 800"

- Is it just going to effect the cpu usage limited server ?

This is different from "one server for 1 or 2 cpu for example", so I'm confuse

What effect the cpu limit will have on other servers?

The CPU limiter tool isn't something I would suggest you use on a routine basis. It was a tool designed for us so we could stop broken servers from using more CPU then they needed. The default limit should be fine for just about all servers.

If I remember correctly the usage is based off of normalized CPU usage which can be found by doing this calculation.

to get to normalized usage, you just multiply the overall cpu usage number that windows gives you by the number of cores

200% usage of an E3-1270 would be 25% of a single core.
400% usage of an E3-1270 would be 50% of a single core

If a server reaches the limit and exceeds it by 25% our system will automatically reboot the server. This tool cannot be used to assign servers to affinities, something we normally don't recommend anyways.

Using the tool shouldn't have any effect on your server unless your server hits that cap and starts getting rebooted.

kraze, wouldn't it go like this:
on an E3-1270 12.5% CPU usage = 100% CPU(one core loaded)

100/8=12.5, so if a core is maxed out, windows would report 12.5% CPU.

I don't mean to confuse here, but your math seems wrong.

Another example:
windows reports 50% CPU usage, normalized=400%

on an E3-1270 maximum normalized CPU for a process is 800% (all 8 cores at 100%)

To answer the OP question the best I can, if you want a game server to be allowed 2 cores, allow it 200% CPU, if it goes over 225% for an amount of time the server will be rebooted. The max of the 8-thread machine is 800%, 100% for each core. The only instance I can see this being useful is some multi-threaded game that will lock up and use all cores.

My math seems to line up with yours.

on an E3-1270 12.5% CPU usage = 100% CPU(one core loaded)

So that's 100% normalized usage

200% usage of an E3-1270 would be 25% of a single core.(12.5x2=25)
400% usage of an E3-1270 would be 50% of a single core(25x2=50)

800% would be 100% usage across all eight cores

Don't let the fact that I said single core confuse you.

[soja]

Yes single core threw me off lol.

The number for the CPU limiter is percentage of a single core.

200% usage of an E3-1270 would be 25% of a single core.(12.5x2=25)

You mean:

200% usage of an E3-1270 would be 25% of the full machine.(12.5x2=25)

In general, you should leave the field blank or set it to 0.
