I personally manages several FreeBSD 5.2-CURRENT instances, and here are my experiences.
FreeBSD 5.x contained many new features, technologies. Currently, it’s clear that 5.2-CURRENT is more stable and have a better performance than 5.2(.1)-RELEASE. Therefore, if you are looking to install a new (of course, and ONLY if you choose 5.x series!) computer, the best solution would be 5-CURRENT.
Robert today has sent a headsup to current@, claiming that he will merge his changes on p4 to cvs soon.
The “Distribution Set” is an important idea on GridDistribute’s vendor distribution. Here comes different ideas on implementing it, which will influence the search approach we will choose. Personally, I think we must have a final decision before next Wednesday.
David O’Brien has announced the -O2 clean for AMD64 platform. Meanwhile, it seems that alpha has a -O2 clean build now!
It’s our pleasure to see GCC 3.4 import to be listed in FreeBSD 5.3-R todo list. Unfortunatelly, gmake is now a required prerequisite when building GCC 3.4, this may slow down the import progress.
It’s a common practise to choose a prime number as the hast table size. This article has analyzed Java’s implementation.
Well I finally can get this into my blog because Microsoft has publicly announced it :-) The information got from my friend has finally confirmed, and this is really exciting!!
Today Tom Rhodes (trhodes@) has committed a massive patch against FreeBSD-HEAD, allowing Intel C/C++ Compiler to build kernel. This change should not change the current gcc based build infrasture.
今天发生的事情让我只能用一个四个字母的单词来形容选课系统——不知道又是哪个学校的研究生设计的，不过，这一次，让人生气的是系统的设计者恐怕没有一点关于性能的常识，系统显然是给一二十人并发访问设计的，而这次选课的人，往少了说也得有三四千……
所有的力量显然都浪费在了做那个华而不实的界面上，用以性能差著称的TomCat承担如此重要的关键性生产服务，而又不采取任何提高性能的措施，例如，分散负荷，或者，仅仅是简单地分散数据库访问，甚至极其简单的将静态页分离的方法。
Profiling based optimization means better performance.
Here’s phk’s suggestion:
We can compile our kernel with "--test-coverage --profile-arcs" to
do basic-block profiling (see kernbb(8) and gcov(1)/gcc(1) docs.)
