tpcc-mysql benchmark

This blog post will detail the results of Samsung storage in tpcc-mysql benchmark using Percona Server. I had an opportunity to test different Samsung storage devices under tpcc-mysql benchmark powered by Percona Server 5.7. You can find a summary with details here https://github.com/Percona-Lab-results/201607-tpcc-samsung-storage/blob/master/summary-tpcc-samsung.md I have in my possession: Samsung 850 Pro, 2TB: This is a SATA device and […]

Benchmark MongoDB with sysbench

In this blog post, we’ll discuss how to benchmark MongoDB with sysbench. In an earlier post, I mentioned our use of sysbench-mongodb (via this fork) to run benchmarks of MongoDB servers. I now want to share our work extending sysbench to make it work with MongoDB. If you’re not familiar with sysbench, it’s a great project developed […]

Evaluating Database Compression Methods: Update

and  | April 13, 2016 |  Posted In: Benchmarks, MySQL

Database Compression Methods

This blog post is an update to our last post discussing database compression methods, and how they stack up against each other.  When Vadim and I wrote about Evaluating Database Compression Methods last month, we claimed that evaluating database compression algorithms was easy these days because there are ready-to-use benchmark suites such as lzbench. As […]

Percona Server 5.7 performance improvements

In this blog post, we’ll be discussing Percona Server 5.7 performance improvements. Starting from the Percona Server 5.6 release, we’ve introduced several significant changes that help address performance problems for highly-concurrent I/O-bound workloads. Some of our research and improvements were re-implemented for MySQL 5.7 – one of the best MySQL releases. But even though MySQL 5.7 […]

InnoDB and TokuDB on AWS

 | February 1, 2016 |  Posted In: Benchmarks, InnoDB, TokuDB

In a recent post, Vadim compared the performance of Amazon Aurora and Percona Server on AWS. This time, I am comparing write throughput for InnoDB and TokuDB, using the same workload (sysbench oltp/update/update_non_index) and a similar set-up (r3.xlarge instance, with general purpose ssd, io2000 and io3000 volumes) to his experiments. All the runs used 16 threads for sysbench, and the following […]

Apache Spark with Air ontime performance data

 | January 7, 2016 |  Posted In: Apache Spark, Benchmarks, MySQL

There is a growing interest in Apache Spark, so I wanted to play with it (especially after Alexander Rubin’s Using Apache Spark post). To start, I used the recently released Apache Spark 1.6.0 for this experiment, and I will play with “Airlines On-Time Performance” database from http://www.transtats.bts.gov/DL_SelectFields.asp?Table_ID=236&DB_Short_Name=On-Time. You can find the scripts I used here https://github.com/Percona-Lab/ontime-airline-performance. The uncompressed dataset is about 70GB, which is […]

MongoDB 3.2 WiredTiger in iiBench

 | December 15, 2015 |  Posted In: Benchmarks, MongoDB

MongoDB 3.2 was recently released with WiredTiger as the default storage engine. In just over five years, MongoDB has evolved into a popular database. MongoDB 3.0 supported “pluggable storage engines.” The B-Tree-based WiredTiger should outperform IO-optimized RocksDB and PerconaFT in in-memory workloads, but it demonstrates performance degradation when we move into IO workloads. There are reports that WiredTiger […]

The MySQL query cache: Worst enemy or best friend?

 | August 7, 2015 |  Posted In: Benchmarks, MySQL

During the last couple of months I have been involved in an unusually high amount of performance audits for e-commerce applications running with Magento. And although the systems were quite different, they also had one thing in common: the MySQL query cache was very useful. That was counter-intuitive for me as I’ve always expected the […]
