jian ru 3fc817fb6d Add a separate upload limit r.VT.MaxUploadsPerFrame.Streaming for streaming VT pages. When the cvar is not zero, it enables the separate limit and r.VT.MaxUploadsPerFrame will only constrain non-streaming VT pages. When the cvar is zero (currently default), it disables the separate limit for backward compatibility. The motivation to separate SVT pages from other types of VT pages is mainly three-fold: 1) limiting SVT page uploads also throttles the number of loading requests. On platforms where I/O is slow, we may want to let more SVT page requests to go through so that I/O can be initiated earlier to reduce delay in obtaining page data; 2) SVT pages are usually cheaper to produce than RVT pages because they just upload the loaded data to GPU; 3) long standing SVT page requests can block the requests for other types of pages even if the other pages can be requested in parallel and turned around faster. ...
