了得網計算機/網絡_Solaris 性能與工具（英文版）

內容簡介

本書全面介紹了Solaris 10和OpenSolaris中的強大工具，包括Solaris動態跟蹤工具、DTrace和MDB(模塊調試器)。書中提供了理解性能和行為的繫統方法，包括：
● 分析內核和應用程序的CPU利用率，包括讀取和理解硬件計數器。
● 進程級資源使用和概要描述。
● 磁盤IO行為和分析。
● 繫統和應用程序級的內存使用。
● 網絡性能。
● 內核監視和概要描述，以及收集內核統計數據。
● 使用DTrace提供者和聚集。
● MDB命令和完整的MDB指南。
對任何水平的Solaris 10和OpenSolaris用戶來說，本書和《Solaris內核結構》都極具參考價值。

作者簡介

Richard McDougall，Sun公司傑出工程師，專門從事OS技術和繫統性能的研究。
