Is disk Everything for MySQL Performance ?

I read very nice post by Matt today and it has many good insights though I can’t say I agree on all points. First there is a lot of people out where which put it as disk is everything. Remember Paul Tuckfield saying “You should ask how many disks they have instead of how many […]

How to use tcpdump on very busy hosts

Often I run into problems when trying to use mk-query-digest with tcpdump on “very” busy hosts. You might be thinking, “very busy is a relative and unquantifiable term,” and you’d be right, so I’ll phrase this differently. Let me give a little background to the problem first. Mk-query-digest tries to handle dropped or missing packets […]

Performance or Stability ???

Sometimes the question is put like are you looking for Performance OR Stability, which I believe is a strange way to put it. In real life systems you care both about Performance AND Stability. I would even say Stability is a not the best world here, I would day you care about your minimal performance […]

What’s up with HandlerSocket?

I’ve presented at two different venues about HandlerSocket recently and the number one question that always arises is: Why hasn’t HandlerSocket become more popular than it is?

Virident tachIOn: New player on Flash PCI-E cards market

(Note: The review was done as part of our consulting practice, but is totally independent and fully reflects our opinion) In my talk on MySQL Conference and Expo 2010 “An Overview of Flash Storage for Databases” I mentioned that most likely there are other players coming soon. I actually was not aware about any real […]

How Percona Develops Open-Source Software

Percona has been building and contributing to open-source software since the company was founded, and individually we’ve been doing the same thing for many years.  We think it’s a huge value for our customers and the community. We’re involved in a dozen or so open-source projects, but our three core efforts at the moment are […]

Living with backups

Everyone does backups. Usually it’s some nightly batch job that just dumps all MySQL tables into a text file or ordinarily copies the binary files from the data directory to a safe location. Obviously both ways involve much more complex operations than it would seem by my last sentence, but it is not important right […]
