| | ONJava.com: Software Infrastructure Bottlenecks in J2EE |
 | | There can be two possibilities that lead to bottlenecks: the hardware becomes the bottleneck before the software, or the software becomes the bottleneck before the hardware. | | | The solution to alleviate this bottleneck normally is to use software clusters or tune the software. | | | In this article, we try to analyze the case in which the software infrastructure becomes a bottleneck, long before any of the hardware resources (such as CPU, memory, disk space, and network speed) are fully consumed. |

| | Basic Bottleneck Configuration |
| | The bottleneck is between the two routers, where traffic must traverse a 1.5Mbps link. | | | We also see that the congestion window, depicted in Figure 10(b) reaches a peak value of 18 packets, which is the sum of the BWDP (16.5) and n. | | | The bandwidth delay product (BWDP) of this configuration is equal to 16.3Kbytes; therefore, in order to accommodate up to a windowful of data, the routers are set to hold 17 packets. |

| | Bottleneck - Wikipedia, the free encyclopedia |
| | In computer science, some authors refer to the von Neumann bottleneck between processor and memory. | | | More generally, a bottleneck is one process in a chain of processes, such that its limited capacity reduces the capacity of the whole chain. | | | It may be due to a narrow bridge or tunnel, a deep cutting or narrow embankment, or work in progress on part of the road or railway. |
