.NET MSIL: How commands detect size of operands?

阅读更多关于 .NET MSIL: How commands detect size of operands?

问题 There is a single add command in MSIL to add two arguments (pop from stack, add, push into stack). How does it know whether it has to pop 2 bytes or 4 or 8 bytes?

The jitter knows the

问题 I have setup and Azure VM and installed a monitoring service that reaches out to various endpoints to verify a 200 response. The service is set to cycle through about 8 URL endpoints every 5 minutes or so. We have run this service from multiple other servers outside of Azure, including virtual machines that are cheap, low end offerings. While this machine is running on the lowest A0, it isn't doing anything else other than to run this service and call out to the various endpoints. We are

VMware Player VM - 1 core CPU limitation

阅读更多关于 VMware Player VM - 1 core CPU limitation

问题 I'm using a VM with VMware Player to write code and compile. As my current program is huge, the compilation takes a while to be done (upto 5 minutes) using 25% of my 4 cores CPU on my host = 100% of one core.

Thanks 回答1: It sounds like you're limited by the number of parallel build tasks you can run, not the VM CPU configuration, e.g.
