At Percona, we consider it important not only to have the best peak performance, but also stable and predictable performance. I refer you […]

FlashCache: tpcc workload

This is my last post in series on FlashCache testing when the cache is placed on Intel SSD card. This time I am using tpcc-like workload with 1000 Warehouses ( that gives 100GB of data) on Dell PowerEdge R900 with 32GB of RAM, 22GB allocated for buffer pool and I put 70GB on FlashCache partition […]

FlashCache: first experiments

I wrote about FlashCache there, and since that I run couple benchmarks, to see what performance benefits we can expect. For initial tries I took sysbench oltp tests ( read-only and read-write) and case when data fully fits into L2 cache. I made binaries for FlashCache for CentOS 5.4, kernel 2.6.18-164.15, you can download it […]

Looking on 5.4 – IO bound benchmarks

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 […]
