The other day a customer asked me to do capacity planning for their web server farm. I was looking at the CPU graph for one of the web servers that had Hyper-threading switched ON and thought to myself: “This must be quite a misleading graph – it shows 30% CPU usage. It can’t really be […]

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 […]
I continue my benchmarks of Intel SSD 910, previous time I compared it with Fusion-io ioDrive http://www.percona.com/blog/2012/09/07/intel-ssd-910-in-tpcc-mysql-benchmark/. Now I want to test this card against RAID over spinning disks.
I continue my benchmarks of Intel SSD 910, the raw IO results are available in my previous experiment. Now I want to test this card under MySQL workload to see if the card is suitable to use with MySQL. Benchmark date: Sep-2012 Benchmark goal: Test Intel SSD 910 under tpcc-mysql workload and compare with baseline […]
I have a chance to test a system with Intel 320 SSD drives (NewRelic provided me with an access to the server), and compare performance with SAS hard drives.
Having two big boxes in our lab, one based Intel Nehalem (Cisco UCS C250) and second on AMD Opteron (Dell PowerEdge R815), I decided to run some simple sysbench benchmark to compare how both CPUs perform and what kind of scalability we can expect.
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.
Sun is aggressively pushing T2000 as Scalable MySQL Platforms, and indeed it is Scalable in terms of high concurrency workloads – it is able to execute a lot of concurrent threads and so speed gain from 1 thread to say 32 thread will be significant. But thing a lot of people miss is – Being […]
AnandTech published Intel Woodcrest preview benchmarks which have some numbers for MySQL as well. From these numbers performance looks great and it looks like finally Intel has something to respond to AMD Opterons on Server market. Now competition heats up and we’ll see what AMD will have to respond. As Opteron did not have serious […]
In this blog post, we will discuss MySQL performance on eXFlash DIMMs. Earlier we measured the IO performance of these storage devices with sysbench fileio. Environment The benchmarking environment was the same as the one we did sysbench fileio in. CPU: 2x Intel Xeon E5-2690 (hyper threading enabled) FusionIO driver version: 3.2.6 build 1212 Operating […]
