网页loading跟带宽，网络延迟，处理器速度，浏览器引擎（rendering & scripting）

完全不cap usage，很快移动电视之类的就会大行其道，运营商就苦逼了。 |

the social network's new "App Center" tab showing up in the navigation menu

that never happened before. The craziest thing is that those data usage
happened at midnight at home with wifi on. I called At&t, the representative
suggested to turn the cellular usage off manually to avoid data overage.
Anyone has similar experience? |

发帖数: 101 | 13 Your understanding about hash join's memory usage might not be correct.
Hash join only requires around sqrt(data size) to do in memory join. Even
though you are joining terabytes data, hash join can still do in-memory join
with around 300MB memory, which is the power of hash join.
I wonder how much memory hash join is using in your case. This depends
whether you are using automatic memory management in 10g. Hash join's
memory usage is not related to memory buffer or SGA which can be influenc |

a. First look at sp_who2 active to see how many connections are and who is

not identified, use trace later if cannot find answer in the following
items.
b. Look at data file and log file, Shrink if necessary.
c. Look at usage of CPU, memory to see if any bottleneck. 80% of CPU
usage can be recognized as a bottleneck.(if my memory does not go wrong). (use perfmon) |

发帖数: 36252 | 24 the question is, what do you do on the laptop?
if just regular daily usage, 2GB is enough. more than 2 is waste of money
because the extra memory will have 0% usage.
usually computers are slow because there are too many programs loaded at
startup, and anit-virus. If you are running Macfee, 99% of the slowness is
caused by it. and again, extra memory will do absolutely nothing here. |

First of all, in my area, ComCast is the only broadband carrier. They
had crushed all those smaller players who had been here a couple of

Secondly, they are pushing out the cap without supplying a usage
meter, which is insane. The only explanation you can read is that they
do not want a client if his usage is even close to the cap. Second
offence, then they will kick you out. They actually hate you so much! |

your DSN. supposed the name is "example".
