When you only need to send a message with a specific priority, you need to use the equal sign qualifier. Exclamation point (!)

I recently tested the domino platform for a project. During this process, I found some mistakes in the description of many documents on the Internet, next we will deploy Domino + QuickPlace + Sametime (do, qP, and ST respectively) from the beginning ). I. Preparations This deployment uses the domino7 series, Chinese environment, no cluster (Single Server), qP and St integration. Other server configurations are not qualitative, but the memory should be above

QP to a simple scene, allocates a smaller qp for a complex scene, and obtains a basic stable output visual quality. Compared to CBR, the output of VBR is much better than CBR in the same file size, which facilitates media download and local storage. The disadvantage of VBR is that the output code stream size is not controllable. At the same time, there is no advantage for content with constant complexity, such as news broadcasts.ABR codes assign fewer bits to a simple scene, leaving enough bits

of frequent GC: Memory jitter (churn), in which a large number of objects are created and released immediately in a short period of time. Generating a large number of objects in an instant can seriously occupy young generation's memory area, and when the threshold is reached, the GC will also be triggered when there is not enough space left. Even though each allocated object requires little memory, stacking them together increases the pr
