PerfMon 和 w3wp？
我正在 PerfMon 中查看“Process:w3wp*:% Processor Time”，并且正在努力跟踪某些内容。我有运行 w3wp 的跟踪，然后运行 w3wp#1 - w3wp#6，这是服务器上运行的六个站点。
w3wp 的跟踪似乎与 #1-#6 的总数无关？
例如 '#1 可以拥有高于 w3wp 的%处理器，相反，当所有其他 % 都非常低时，w3wp 可以接近 100%。
我试图找到我们服务器中的性能瓶颈，最明显的就是 CPU 达到极限。我们将添加另一个 CPU（因为它在虚拟机上），但我想尝试了解我正在查看的内容......以及可以采取哪些措施来缓解该问题？
为什么个别网站的利用率很低，但w3wp却常常接近100%？如果不是特定网站，是什么导致 w3wp 如此之高？

I'm looking at "Process:w3wp*:% Processor Time" in PerfMon and am struggling to follow something. I have traces running for w3wp and then w3wp#1 - w3wp#6, which are the six sites running on the server.
w3wp's trace doesn't appear to be related to the total of #1-#6 ?
e.g.
'#1 can have a %Processor higher than w3wp, and conversely w3wp can have near 100% when ALL the other %'s are very low.
I'm trying to find a performance bottleneck in our server and the obvious one is that the CPU tops out. We are going to add another CPU (as it's on VM) but I'd like to try to understand what I am looking at...and what can be done to alleviate the issue?
Why is w3wp often close to 100% even though the individual sites are very low? What might be causing w3wp to be so high if its not a particluar site?
ps. If anyone has a way I can save an image here I can post the graph. TY
