Is your MySQL Server Loaded ?

So you’re running the benchmark/stress test – how do you tell if MySQL server is really loaded ? This looks like the trivial question but in fact, especially when workload consists of simple queries I see the load generation and network really putting a lot less load on MySQL than expected. For example you may […]

Tuning for heavy writing workloads

For the my previous post, there was comment to suggest to test db_STRESS benchmark on XtraDB by Dimitri. And I tested and tuned for the benchmark. I will show you the tunings. It should be also tuning procedure for general heavy writing workloads. At first, <tuning peak performance>. The next, <tuning purge operation> to stabilize […]

Scaling IO Bound Workloads Webinar

I will co-present in webinar on Performance Challenges and Solutions for IO Bound Workloads in MySQL. My part of the presentation will be speaking about why switching from CPU bound workload to IO bound is such an important event, how to prepare to it as well as how to keep your application performance good as […]

5.4 in-memory tpcc-like load

As continue to my benchmarks http://www.percona.com/blog/2009/04/30/looking-on-54-io-bound-benchmarks/ on 5.4 I tried in-memory load (basically changed buffer pool from 3GB to 15GB, and database size is 10GB). The results are on the same spreadsheet http://spreadsheets.google.com/ccc?key=rYZB2dd2j1pQsvWs2kFvTsg&hl=en#, page CPUBound. I especially made short warmup (120 sec) and long run (2700sec) to see how different versions go through warmup stage. […]

XtraDB in CPU-bound benchmark

Peter said me that previous results http://www.percona.com/blog/2008/12/18/xtradb-benchmarks-15x-gain/ are too marketing, and we should show other results also. Here is the run for CPU Bound,or it would be more correctly to say in-cache benchmark, because there is a lot of CPU remains idle. This run is exactly the same as Disk Bound but with innodb_buffer_pool_size=8G which […]
