postgresql - Slony-I replication CPU usage -

-

I recently had to install slony (version 2.0.2) at work, all is well, though my owner During copying, want to reduce CPU usage on slave nodes, searching on the net does not provide any clear answer. Any suggestions that will help in reducing CPU usage (or long-term updates will spread) will be greatly appreciated!

Have you seen the general postgresqual tuning? If there is not enough resources available to work with the server, then the server can work in many CPU cycles, and default configurations are very low. Here is a useful guide, shared_buffers and checkpoints_segment are two criteria, which you can use on slave Can achieve some significant improvements (many others only help in improving query time only)

After selecting the copies of the buffer in Linux, after the text, we can click and paste the button between the mouse. I think there is a special buffer for this, I want to use it. Programming Language: C ++ Your Library: Qt Thanks. There is just one more correct answer than Paul Dixon, which answers your needs: / P > QClipboard * clipboard = QApplication :: clipboard (); CastString Selected Text = Clipboard-> Text (QClipboard :: Selection);

I am on a shared hosting server, so please tell me some ways to use the code, because I can not make any modifications at the end of the server. If I expire the header, then there is no chance that if I make changes to the CSS, then the user will not be able to remove them immediately because CSS and other files have a fixed time limit (1 month, week ) Are cached for.

sql server - How can I determine which of my SQL 2005 statistics are unused? -

After a few years, one of my biggest databases has deposited 73 figures out of its largest tables. With Indexes, I can run many types of reports and queries, how often / heavily specific indexes are used. What is an equivalent for data? We are running SQL 2005. To make statistics automatically managed and honest, I would like to "update statistics", "create statistics" and There is no information about any management except "drop statistics" orders. In theory, UPDATE should handle the addition and removal of statistical data. In addition, I've never heard about the amount of storage or storage taking in large amounts, so I'm not sure whether there is any reason for the alarm or not. If you are seeing a potential problem, then I would suggest running an update before, if it does not clean it, it is leaving and then it appears to be safe operation (because it is the only query optimizer Is for). I will not leave "left" in the
