- The Myth of Bandwidth and Application Performance
- Application performance on the WAN is affected by a large number of factors in addition to bandwidth. The notion that bandwidth solves all, or even most, application performance problems is a complete myth. At the network level, application performance is limited by high latency, jitter, packet loss, and congestion. At...

- Accelerators for High Performance Computing Investigation
- For many years microprocessor single thread performance has increased at rates consistent with Moore's Law for transistors. In the 1970s-1990s the improvement was mostly obtained by increasing clock frequencies. Clock speeds are now improving slowly and microprocessor vendors are increasing the number of cores per chip to obtain improved performance....

- Limit connections to a Windows 2000 Professional share
- By default, Windows 2000 Professional is limited to no more than 10 concurrent connections. Anyone trying to connect after the maximum number of connections is reached receives an error message, and the connection is refused. In some situations, you might want to further restrict the number of concurrent connections, whether...
