VMware ESX Server is the most popular virtual software PRODUCT on the Intel platform on the current server market. Compared to other virtual software products, the greatest advantage of ESX is that it can greatly reduce the resources occupied by the host system. The ESX server kernel runs directly above the hardware, and the system stability and performance are greatly improved. ESX server is also well-suited for enterprise applications because it sup

Label:For the full stack, database skills are indispensable, relational databases or NoSQL, memory-based database or partial disk storage database, object storage database or graph database ... , but the first essential skill should be MySQL. From the rise of lamp, to the advent of mariadb, and even the advent of PG, skilled MySQL skills are very useful. MySQL database technology is also a lot of aspects, here is only the necessary performance

Optimized tuning of TCP/IP and kernel parametersThere are many ways to optimize TCP/IP and kernel parameters under Linux, the configuration of parameters can greatly improve the performance of the system, and can also be optimized according to specific scenarios, such as time_wait, DDoS attacks and so on.The following configuration is written in sysctl.conf and c

BEA WebLogic jrockit usage and Performance Tuning 1. Introduction to jrockit OptimizationJrockit is an adaptive JVM that can automatically adjust itself to adapt to the underlying hardware. Therefore, its optimization is mainly focused on parameters that require manual intervention, such: the number of Ram resources to be allocated to jrockit. Jrockit has a set of non-standard-x startup options that we can
