MaxScale, ProxySQL and MySQL Proxy
+2 Vote Up -0Vote Down

At FOSDEM 2014 ProxySQL and MaxScale were both presented. Both are proxy that can help build sophisticated MariaDB/MySQL architectures. But currently what is the most used proxy with MySQL? It is HAproxy. HAproxy is a level 4 proxy that has no knowledge of the MySQL protocol. Being low level makes it very fast but it [...]

Configuring MySQL Server for Optimal Performance
Employee_Team +0 Vote Up -0Vote Down

Configuring MySQL Server, with the dozens of options available, has always been perceived as a bit of a black art. In MySQL Database 5.6, configuring your MySQL server for optimal performance is easier than ever before.

In the MySQL for Database Administrators course you can learn more.

MySQL 5.6 is configured to work faster out of the box in a wide range of installation scenarios and it is easier than ever to set up the server by adjusting only a small …

More on 40% better single-threaded performance in MariaDB
+1 Vote Up -0Vote Down

In my previous post I wrote about how I achived a >40% speedup on sysbench read-only using profile-guided optimisation (PGO). While this is a preliminary result, I though it was so interesting that it deserved early mention. The fact that any benchmark can be improved that much shows clearly that PGO is something worth looking into. Even if we will probably not improve all workloads by 40%, it seems highly likely that we can obtain significant gains also for many real workloads.

I had one or two interesting comments on the post that raise valid concerns, so I wanted to …

40% better single-threaded performance in MariaDB
+5 Vote Up -0Vote Down

Continuing my investigation of single-threaded performance in the MariaDB server, I managed to increase throughput of single-threaded read-only sysbench by more than 40% so far:

I use read-only sysbench 0.4.12 run like this:

    sysbench --num-threads=1 --test=oltp --oltp-test-mode=simple --oltp-read-only --oltp-skip-trx run

And mysqld is run with minimal options:

    sql/mysqld --no-defaults --basedir=X --datadir=Y --innodb-buffer-pool-size=128M

With modern high-performance CPUs, it is necessary to do detailed measurements using the built-in …

Transaction life cycle improvements in 5.7.3
Employee_Team +3 Vote Up -0Vote Down

This is part of the ongoing work on improving the transaction life cycle management. In 5.7.2 we split the transaction list into two. The read-only transaction list and the read-write transaction list. There was another "virtual" list, the auto-commit non-locking  read-only (AC-NL-RO) transaction list. The change in 5.7.2 was that by default a transaction was treated as read only and added to the read-only transaction list. Only when it was determined that the transaction was going to do an update we removed the transaction from the read-only list and moved it to the read-write transaction list. This initial add to the the read-only list forced …

Benchmarking the Cloud
+0 Vote Up -1Vote Down

Benchmarking, and benchmarking the cloud, is incredibly error prone. I provided guidance though this minefield in the benchmarking chapter of my book (Systems Performance: Enterprise and the Cloud); that chapter can be read online on the InformIT site. I also gave a lightning talk about benchmarking gone wrong at Surge last year. In this post, I’m going to cut to the chase and …

Improved Performance of Data Export/Import for MySQL Utilities 1.3.6 GA
+0 Vote Up -0Vote Down

The performance of the mysqldbcopy, mysqldbexport, and mysqldbimport utilities has been optimized in MySQL Utilities 1.3.6. In the case of export/import there have been significant improvements. In particular, multiprocessing support has been added to these utilities and can be enabled with the new --multiprocess option. The option permits concurrent execution and makes the most of the CPU resources available (number of cores).

Multiprocessing is applied at different levels according to the operating system. For non-POSIX systems, multiprocessing is limited to the database-level whereas POSIX systems can make multiprocess at the table …
