false 2444036 1 The easy way to solve a performance problem--and the one to which hardware manufacturers love to call attention--is to apply more horsepower to the application in question. It's safe to bet that a server upgrade will speed things up. True information technology professionals, however, won't take the easy way out when dealing with an increased workload for older systems. They'll do their best to wring top performance (with required reliability) from existing hardware, thus improving their organizations' return on capital investment and demonstrating their own engineering skills. The second edition of <I>System Performance Tuning</I> offers advice on where to look for bottlenecks in applications--both local and networked--that run under Unix. It also offers advice on provisioning new systems, which is to say it offers advice on deciding how much computing power is enough for a new system to be implemented.<p> Emphasizing Solaris 8 and, to a lesser extent, Linux, the new version of this book represents a significant revision (the first came out in 1990 and was pretty badly obsolete). There's coverage of advances in hardware--multiple processors, RAID storage, faster and cheaper memory, and networked devices--as well as consideration of changes in the demands placed on machines (after all, few people were concerned about Web server performance in 1990). Administrators will get plenty of value from the authors' discussion of what goes on during, for example, a series of large store-to-disk operations, and be better able to optimize their systems. <I>--David Wall</I><p> <B>Topics covered:</B> How to get top performance from computer systems (those running Linux and especially Sun Solaris 8) without adding processor capacity, memory, and other resources at potentially great expense. The authors explain the ways in which operating systems and applications use processors, memory, persistent storage, and networks, and point out potential bottlenecks. They also show how to use tools--such as execution timers--that you can use to benchmark performance changes. 2451230 1 11 1990 System Performance Tuning (Nutshell Handbooks) total:2|5:2| 2 10 13 0 0 0 false false Wed Aug 26 23:30:13 -0700 2009 Wed Aug 26 23:30:13 -0700 2009 0 0 false false Mon Jul 27 14:38:25 -0700 2009 Mon Jul 27 14:38:25 -0700 2009 0 0 false false Mon Jun 08 05:27:21 -0700 2009 Mon Jun 08 05:27:21 -0700 2009 0 0 false false Fri May 29 17:19:09 -0700 2009 Fri May 29 17:19:09 -0700 2009 0 0 false false Mon Jan 26 19:04:42 -0800 2009 Mon Jan 26 19:04:42 -0800 2009 0 0 false false Fri Jan 16 09:52:51 -0800 2009 Fri Jan 16 09:52:51 -0800 2009 5 0 false false Thu Jan 01 11:15:55 -0800 2009 Thu Jan 01 11:15:55 -0800 2009 5 0 false false Wed Dec 31 11:44:43 -0800 2008 Wed Dec 31 11:44:43 -0800 2008 0 0 false false Mon Sep 08 20:02:11 -0700 2008 Mon Sep 08 20:02:11 -0700 2008 0 0 false false Sun Jul 20 13:41:06 -0700 2008 Sun Jul 20 13:41:06 -0700 2008 0 0 false false Tue Jul 08 06:42:08 -0700 2008 Tue Jul 08 06:42:08 -0700 2008 0 0 false false Thu May 15 01:25:03 -0700 2008 Thu May 15 01:25:03 -0700 2008 0 0 true false Sun Dec 30 09:34:09 -0800 2007 Sun Dec 30 09:34:12 -0800 2007 http://www.goodreads.com/book_link/follow/8?book_id=2444036
