Percona has been providing Answers.com with on demand consulting services for over a year. In this period, they provided some comprehensive diagnostic services to entire systems, as well as smaller tasks to solve specific, acute issues. The Percona team are always available, easy to reach, and extremely knowledgeable about all MySQL performance issues. Just knowing that they are a phone call away has put me much more at ease.

Percona's mySQL consultancy allowed us to overcome issues with replication on one large scale database and to improve performance in another. Peter Zaitsev's level of experience resulted in a number of strong recommendations on how to get the best out of our mySQL implementations.

As CafeMom has grown tremendously over the last year, Percona has been critical in terms of helping us get ahead of the curve and scale our site. In the past it was a very hit-or-miss process to tune our database; Percona made that process much more controlled, where we could truly feel confident that changes that were being made would positively impact performance and scalability. The value they have provided is tremendous.

Drupal.org is the project site for Drupal, a leading open source content management system. As the project got more popular, the site experienced explosive growth, causing significant slow downs for visitors. Percona helped by analyzing several slow queries and recommending how they can be changed to perform better. Their in depth knowledge of MySQL helped pinpoint the problem effectively, and also coming up with a solution in a timely manner.

The guys from Percona are amazing. I can say with confidence that our website would not be as successful as it is without their help. They have helped us with optimizing MySQL queries, MySQL administration, and just general infrastructure consulting. They are very personable, friendly, and trustworthy. They are also available for emergency help, which is very reassuring. Knowing that they are available to help when things take a turn for the worst is a feeling that is worth more than money.

Running a Linux Cluster with over 2 Mio. downloads every day as a small company sometimes causes strange and unforseen problems. The guys at Percona were extremly helpful, professional and fast when our servers crashed - even in the middle of the night. If you are looking for affordable professionals to speed up your applications and have a stable server environment - you are at the right place!

The Percona experts have done an excellent job in recovering vital information from some tables that we lost after an unfortunate upgrade. Within a week we were able to recover all of our data. These guys really know what they're doing and I would happily recommend them to anyone facing MySQL recovery issues.
