p***p 发帖数: 559 | 4 There is lots of timer taskes in my software, such as session time out, auto-
reload and clean.... I use TimerTask.run and Timer.schedule(...) to implement
them.
In order to save rescoure, I use a single Timer for all such taskes in my
Application(somehow as a static). My question is, could it be a performance
hit when tousand such taskes running on single Timer, or i'd better use more
timers. |

n*******t 发帖数: 1296 | 6 以前用的的是那种机械的Timer, 很大一个问题就是Water Hammer。我还发帖子问过这
个事情。昨天去HD买了电子的Timer(产品链接见后)。今天试用了一下,效果不错。
1。 可以定时,比如说什么时候开始浇水,是每天浇,还是每隔几个小时就浇一次。
2。完全没有Water Hammer了。电子Timer用的是ball valve,每次关水都是慢慢关上的
,所以没有Water Hammer。以前的机械Timer用的是Diaphram valve,每次关水都有很
大的震动。
3。我用了一个Y tube,可以把一个龙头分成两个,这样一共就可以有四个水管,前院两
个,后院两个。全部定时浇水。
我的Lot size是0.36 acre,四个水管基本可以覆盖。定好时间,放好水管后就不用管
了。
这样一来,效果其实和sprinker system就差不多。
希望对没有spinkler system,又对浇水不胜其烦的同志有所帮助。

1)每隔200ms从服务器读取一个股票数据
2)进行数据分析
3)图形显示
这个1和3是用两个timers好,还是合用一个timer好?
另外,2 需要用一个单独的timer吗?还是和1合用一个timer
如果,每隔200ms从服务器读取5个股票数据,
分别数据分析,然后分别图形显示。
请问这种情况需要分5个线程来编程吗? |

下面的图是10张拼合而成的。。涉及头灯光(tent),月光,星光,阳光(鱼肚白),
晚上10点过拍了帐篷后,我设置了晚上12点开始(因为11:40PM月出),每半小时拍一
张,直到早晨6点。
此前又拍星轨一张(说实话我已经有些拍厌了。。:P),曝光1个半小时,Joshua

顺手再加一张星空御帐,本是所谓构图用的,ISO设了1600.。 |
