The PBXT Storage Engine (http://www.primebase.com/xt/) is getting stable and we decided to benchmark it in different workloads. This time I tested only READ queries, similar to ones in benchmark InnoDB vs MyISAM vs Falcon (https://www.percona.com/blog/2007/01/08/innodb-vs-myisam-vs-falcon-benchmarks-part-1) The difference is I used new sysbench with Lua scripting language, so all queries were scripted for sysbench.

Finally I was able to run PBXT 1.0.11 pre-GA in tpcc-like workload, apparently there was bug with did not allow me to get the result earlier, and I am happy to see that PBXT team managed it. For initial runs I took tpcc 100 warehouses ( about 10GB of data) which fully fits into memory […]
Following on from our earlier announcement, Paul McCullagh has responded with the answers to your questions – as well as a few I gathered from other Percona folks, and attendees of OpenSQL Camp. Thank you Paul! Whatâ€™s the “ideal” use case for the PBXT engine, and how does it compare in performance? Â When would I […]
I promised to write little articles about all storage engines which sessions I attended during MySQL Users Conference but I did not get too far yet, too busy. So today it is time for PBXT. I was very interested about session about PBXT because this is storage engine does not target the same general purpose […]
Few weeks ago I wrote about Innodb Caching with main idea you might need more cache when you think you are because Innodb caches data in pages, not rows, and so the whole page needs to be in memory even if you need only one row from it. I have created the simple benchmark which […]
I have mentioned few times Innodb caches data in pages and even if you have working set consisting of relatively few rows your working set in terms of pages can be rather large. Now I came to do a little benchmark to show it in practice. I’m using standard “sbtest” with 10mil rows with data […]
As you may have recently seen there are some articles about scaling MySQL one 256-way system. I though wow did they really make it work, considering how many bottlenecks remain in MySQL. What article really tells us ?
OK, I am not getting too much people feedback on what would they like to hear about on MySQL Users Conference, so I went ahead and submitted few presentation ideas. I do not expect all of them would be accepted, furthermore it would be hard to prepare so many good presentations if they are so […]
Quite frequently I run into question like this “I’m using SQL_NO_CACHE but my query is still much faster second time I run it, why is that ? The answer to this question is simple – because SQL_NO_CACHE only bypasses query cache but it has no change on other caches, which are MySQL Caches – Innodb […]
Vadim and me will be speaking on OSCON 2007, taking place in Portland,OR July 23-27. Our talk will be about Open Source Transactional Storage Engines meaning Innodb, Falcon, Solid and PBXT. We’ll look into architecture of these storage engines as well as compare performance in number of Benchmarks. If you will be visiting OSCON please […]
