@lolicon 现在速度好些了,因为时间晚了,我明天再跑一次,这几天准备把跑的结果存数据库分析下


@bellchu 上海掉包44%,江苏掉包22%,可能是你说的原因吧,所以现在开始要卖国精了

什么网？

程序怎么知道这是噪音不是照片上本来就有的灰尘？

@yangyang 大哥,讨论问题不需要这么傲娇好吗?你的overlay是jffs2格式,所以你能free space,不是因为你是Squashfs
装在squashfs上的包是没法free的

OpenWRT uses squashfs. Read about squashfs at http://en.wikipedia.org/wiki/SquashFS

In short you cannot remove preinstalled packages such that flash space it released. But preinstalled packages have the advantage of being compressed in flash and therefor take a lot less flash space. Packages installed using opkg are not compressed on your router so they are less efficient in regards to the amount of flash space they occupy but they can be removed.

To do what you want you need to build your own version of openwrt using make menuconfig to select the packages you want preinstalled.

@yangyang
取决于你是不是SquashFS
SquashFS is a read only compressed filesystem. While gzip is available, at OpenWrt it uses LZMA for the compression. Since SquashFS is a read only filesystem, it doesn't need to align the data, allowing it to pack the files tighter thus taking up significantly less space than JFFS2 (20-30% savings over a JFFS2 filesystem)!

+ taking up as little space as possible
+ allowing the implementation of an idiot proof FailSafe for recovery, since it is not possible to write to it
- read only
- waste space, since each time a file contained on it is modified, actually a copy of it is being copied to the second (JFFS2) partition

你的可能不是squashfs,输条mount来看看?

早就百兆了啊

@yangyang openwrt那格式删软件空间也不会回来

arm总体速度就是一个坑，问题不是内存是cpu

@rainy3636 哪有 我都想测一下速

@lolicon 美国的主机，我电信连过去就不是联通出口了啊

要大了不少吧openwrt上大家最在意的就是包大小了

上万台设备，你得用cassandra，否则怎么撑的住？

我们有关系数据库，外键有时还是用的，但只用在很小的人工生成的表上，一些从log上import进来的表，不可能用外键，只能roll up了用的时候再sp里join或代码上join

google apps不免费，但我怎么在免费用？

我一直吃维生素b2，几块钱，比吃什么枸杞方便

不是fb问题，大陆现在国际出口一到晚上，惨不忍睹

@icedx 哦，没注意到，你是windows客户端，我没windows，我mac和android上一切正常

我一切正常

@levie 好吧，我知道我邪恶了
