发帖数: 1072 | 1 Just try a littlbe bit.What you need to do is:
1.Make sure the application path in IIS metadata is the same for every
server(use metaedit.exe to check)
2.use the same descryption and validation key on every server(in
machine.config)
3.use StateServer or SqlServer to maintain the session information
4.Load Balancing. |

原因很简单，没有足够的内存做 caching 来 merge IO.
导致 metadata 被频繁读写，增加很多磁盘 seek。 |

发帖数: 7142 | 14 我觉得，路由和硬盘服务 NAS 应该分开。
路由器一般内存太小，metadata caching 少，读写文件对硬盘磁头
移动多，比较毁硬盘。USB 接口连 SSD 的土豪当我没说。而且 USB
接口比不上直接 SATA 接口的简单 NAS 快。
如果你要一个稳定，性价比高的普通路由，不是发烧友路由，
可以考虑 TPLINK WDR 3600。 amazon 56 刀左右。8M flash 128M ram。
跑 Openwrt 很完美。我家有这个。
synology214play 的价钱还不如搞个 Acer 603g J1900 CPU。
就算不装 Linux， 用 Windows 做 video 和文件服务都比
214play 强很多。我自己用 Linux 加 xbmc 很 happy。 |

没有。基本原理都不一样。你懂文件系统？ext4这样的文件系统，inode都是
hierarchical的，metadata都在各个目录树节点上。嚷嚷写个文件要几G的缓存，是你
吧？以为写个文件人把整个目录树都加载到内存然后再全部写回去？
除了zfs这样的需要dedup的文件系统，需要大内存，哪个文件系统读写要几G缓存？

你可以联系它们技术支持，他们会远程连你的synology给取消这个标志位。我也是看论

如果你只是为了增加空间，不要用raid，还不如用jbod或者磁盘组的功能。

OK, let me just remind you guys once again, that Method object is obtained
from a specific Class object. If it only holds the metadata for the method
interface regardless inheritence, the Method objects I got from class A, B,
and C should logically equal to each other, which is evidently not true. |

反之兼容得不错，跟project的metadata有关
要先导出ant，再通过ant脚本构造elicpse程序

发帖数: 2859 | 31 Read the JVM Specs. All field metadata is stored in the permgen (method area
). Static variable each has a reference to a ConstanceValue data structure,
also in permgen. The value can be of type long, float, double, int (short,
char, etc.), and string. The Specs does not specify how a object reference
is stored (or at least I did not find it). Maybe it's like this: if the type
of the field is not primitive, then the value stored in the ConstantValue
data structure is interpreted as an object ref... 阅读全帖 |

发帖数: 2859 | 32 Carefully architect your system to:
1, Create layers.
2, Create loosely-coupled layers.
3, Make layers easily clustered.
4, The horizontal expansion of one layer should not affect other layers, and
should not require down time.
5, Leave hooks for logging/tuning.
6, Make deployment build on convention and metadata driven. |

发帖数: 21578 | 39 The new ext4 mounting option "alloc_on_commit" gives Ext4 a mechanism
analogous
to "data=ordered" in Ext3, whereby metadata is not committed in the journal
until after blocks have been allocated and the data has been written.
However,
this change probably won't arrive until version 2.6.30 of the kernel at the
earliest. |

对了，谁来对 swap 给个意见吧：quad-core CPU, 2X1GB memory，DDR 的，几周后换
成 2X4GB，一年内最高可能升到 8X4GB，同时可能加第二个 CPU。是给 swap 一个专区
呢，还是放在 LVM 里动态调？会不会导致不连续，从而降低速度？设几个 swap 比较
好？2X4G 呢，还是 4X2G，还是直接 8G? 印象中 swap 的数目和 core 的数目有个关
