10 essential performance tips for MySQL

Posted on May 16, 2012 by admin

As with all relational databases, MySQL can prove to be a complicated beast, one that can crawl to a halt at a moment’s notice, leaving your applications in the lurch and your business on the line.

The truth is, common mistakes underlie most MySQL performance problems. To ensure your MySQL server hums along at top speed, providing stable and consistent performance, it is important to eliminate these mistakes, which are often obscured by some subtlety in your workload or a configuration trap.

Luckily, many MySQL performance issues turn out to have similar solutions, making troubleshooting and tuning MySQL a manageable task.

Here are 10 tips for getting great performance out of MySQL.

MySQL performance tip No. 1: Profile your workloadThe best way to understand how your server spends its time is to profile the server’s workload. By profiling your workload, you can expose the most expensive queries for further tuning. Here, time is the most important metric because when you issue a query against the server, you care very little about anything except how quickly it completes.

The best way to profile your workload is with a tool such as MySQL Enterprise Monitor’s query analyzer or the pt-query-digest from the Percona Toolkit. These tools capture queries the server executes and return a table of tasks sorted by decreasing order of response time, instantly bubbling up the most expensive and time-consuming tasks to the top so that you can see where to focus your efforts.

Workload-profiling tools group similar queries together into one row, allowing you to see the queries that are slow, as well as the queries that are fast but executed many times.

MySQL performance tip No. 2: Understand the four fundamental resourcesTo function, a database server needs four fundamental resources: CPU, memory, disk, and network. If any of these is weak, erratic, or overloaded, then the database server is very likely to perform poorly.

Understanding the fundamental resources is important in two particular areas: choosing hardware and troubleshooting problems.

Total revenues increased 26.5% to $2.27 billion, beating the Zacks Consensus Estimate of $2.08 billion.

SITCHIN RIGHT AGAIN? Brazilian astronomer claims that there’s a rogue planet hidden behind Neptune. – Video

Posted on May 16, 2012 by admin


15-05-2012 02:05 Brazilian astronomer/astrophysicist Rodney Gomes, of the National Observatory of Brazil in Rio de Janeiro, made a presentation at the meeting of American Astronomical Society in Timberline Lodge, Oregon, about his theory that there’s a rogue planet hidden behind Neptune, messing with the orbits of the objects of the Kuiper Belt. Depictions of this supposed planet, based in the astronomical model of Gomes, put it as a serious candidate to be the mythic Sumerian celestial body known as NIBIRU.

Iran banning certain use of foreign e-mail providers

Posted on May 16, 2012 by admin

Banks, insurance firms, telephone companies, and their customers can no longer send e-mail from foreign-based addresses, restricting such services as Gmail and Hotmail.

Iran is cracking down on the use of foreign e-mail addresses.

The country’s telecommunications ministry is now barring local banks, insurance companies, and phone operators from communicating with their clients using foreign e-mail providers, according to the AFP news service.

Based on information from Iranian news service Asr Ertebatat, the new order requires such industries to use addresses ending in the Iranian domain .ir, effectively preventing them from using such foreign providers as Gmail, Hotmail, Yahoo, or MSN.

Customers of such companies are also included in the ban, requiring them to use local e-mail addresses in order to do business. Even further, government agencies and universities must also now use addresses in the .ir domain.

The move is part of the Iranian’s government effort to secure and monitor communications in the country by cutting off ties to foreign Internet and e-mail providers, according to AFP.

A recent report claimed that Iran was getting ready to permanently cut off access to the global Internet for its citizens and replace it with its own national Internet.

The government had fiercely denied the report, calling it a “hoax.”

However, the crackdown on foreign e-mail providers follows a previous announcement from Tehran that it would replace the Internet with a national network for government, banks, and other entities.

Yahoo confirms CEO is out after resume scandal

Posted on May 16, 2012 by admin

Scott Thompson, now the former CEO of Yahoo

NEW YORK (CNNMoney) — Yahoo CEO Scott Thompson is out after it was found he padded his resume with an embellished college degree, ending his term at the company after just four months.

Yahoo confirmed Thompson “has left the company” in a statement posted late Sunday, after two news reports. Tech blog AllThingsD was the first to report the news, and the New York Times followed up with its own article.

Yahoo media chief Ross Levinsohn will be named interim CEO, the company said. Levinsohn had earlier been rumored as a successor to Carol Bartz, who was fired from Yahoo by phone in September. Instead, Thompson took the CEO role in January.

Thompson’s resume scandal ignited just over a week ago, when activist shareholder group Third Point alleged that Thompson lied about details of his college degree.

The saga took an even more dramatic twist Monday morning, when the Wall Street Journal reported that Thompson has been diagnosed with thyroid cancer. His decision to step down from Yahoo was “in part influenced” by the recent diagnosis, the newspaper said.

New board members: Dan Loeb, the CEO of Third Point, has a long history of launching proxy fights — and Yahoo was the latest company in his crosshairs. Third Point owns about 5.8% of Yahoo, and is the largest outside shareholder. In February, Third Point filed paperwork proposing four new Yahoo board members, including Loeb himself.

At first, Yahoo didn’t want to play ball. But Third Point scored a coup by finding and exposing Thompson’s padded resume.

Now, Yahoo has settled with Loeb to end the proxy fight. On Sunday, Yahoo and Third Point released a joint statement explaining the terms.

Yahoo will add three of Third Point’s proposed nominees to the board: Loeb himself; Harry Wilson, the CEO of corporate restructuring and turnaround firm Maeva; and Michael Wolf, CEO of media consulting company Activate.
