One of our customers gave me a chance to run some benchmarks on 24-core (intel cpu based) server, and I could not miss it and ran few CPU-bound tasks there. The goal of benchmarks was investigation of InnoDB-plugin and XtraDB scalability in CPU-bound load.

I’ve mentioned InfiniDB before in a previous post titled, “Star Schema Bechmark: InfoBright, InfiniDB and LucidDB,” but it’s been 4 years since that was published. Recently I evaluated column-storage solutions for Percona Cloud Tools and took another look at InfiniDB 4. There was the release of version 4, which I think is worth attention. What […]
Time for another poll! I wonder What CPU Architecture do you use for running MySQL in Production ? I guess most of the game here is between Intel and AMD x86-64 variants though I wonder if there is still a lot of use for others in the wild. If I am missing some Architecture which […]
In my post MySQL 5.5.8 and Percona Server: being adaptive I mentioned that I used innodb-log-block-size=4096 in Percona Server to get better throughput, but later Dimitri in his article MySQL Performance: Analyzing Percona’s TPCC-like Workload on MySQL 5.5 sounded doubt that it really makes sense. Here us quote from his article: “Question: what is a […]
Sometimes when you do profiling you can see number like this in timestamps. Periodically in our patches there was Query_time: 18446744073709550.000 in slow.log file (well, it was fixed recently, but still appears in other places). I faced this problem several years ago when only 2-core AMD Opteron systems appeared and I noticed sysbench getting crazy […]
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. […]
With a lot of talks around 5.4 I decided to check how it works in our benchmarks. For first shoot I took tpcc-like IO-bound benchmark (100W, ~10GB of data, 3GB buffer_pool) and tested it on our Dell PowerEdge R900 box (16 cores, 32GB of RAM, RAID 10 on 8 SAS 2.5″ 15K RPM disks). For […]
MySQL 5.4 comes with Innodb engine which seems to have much better performance than MySQL 5.0 – this is due to locking and IO patches from Google integrated in this release (which are similar to appropriate Percona patches) as well as some unique fixes such as different innodb_thread_concurrency handling and other optimization. Should we take […]
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 […]
We’ve recently done benchmarks comparing different MySQL versions in terms of their CPU efficiently in TPC-C like Workload. We did it couple of weeks ago so MySQL 5.0.67, MySQL 5.1.29 and Innodb Plugin 1.0.1 were used which are not very recent, though we do not think results will differ a lot with today versions.
