Wine-Staging 1.7.39 Works On Speeding Up Wineserver Calls
Beyond the existing Wine-Staging-only features like DXVA2 API, Threadpool and CUDA 7, GPU PhysX support, and other functionality, the 1.7.39 update adds a bit more.
The Wine-Staging 1.7.39 release in particular has focused on speeding up one of the slowest areas of Wine: calls to the wineserver. The wineserver handles calls that Windows programs normally make to the Windows kernel, but in the case of Wine are passed to this program. Wine-Staging 1.7.39 adds a new shared memory communication method and optimizations to frequently used functions. The speed-ups though are hidden behind a STAGING_SHARED_MEMORY environment variable and also require Linux 3.17+ for file sealing and memfds support.
