It's calculated as follows: grep VmPeak /proc//status Since we’re using a large shared buffer (100GB), we've set the huge pages parameter accordingly so that the entire shared buffer fits into that. Using huge pages reduces overhead when working with large contiguous chunks of memory, as PostgreSQL does, particularly when using large values for shared_buffers. Here are the operating system specifications that we used for the test: Poorly configured OS kernel parameters can cause degradation in database server performance. It is imperative that we configure the OS parameters according to the database server and its workload. The CPU and memory consumption by the pgbench processes are also negligible. Hence, we can assume that the effect of network latency is negligible. We configured the pgbench on the same server as our database server instance. Pgbench -c $threads -j $threads -T 1800 -M prepared postgres We performed 30 minute read-write pgbench tests across different client counts (1, 16, 32, 64, 128, 256, and 512). The scale factor that we used for the test is 10,000, which generates approximately 150GB of data. In our case, we used the default scripts for the pgbench read-write test. However, you can provide your own scripts for the test. By default, pgbench runs a TPC-B-like script that includes simple UPDATE, SELECT, and INSERT statements. The most popular tool for measuring the performance of PostgreSQL is pgbench. In this post, we share the benchmark testing results that we’ve performed across different PostgreSQL versions (v9.5.21 to v12.1) on an AWS m5.metal instance.ģ.1 GHz Intel Xeon Platinum 8175 processors with new Intel Advanced Vector Extension (AVX-512) instruction setĭata is kept in a 300GB SSD with 2000 IOPS, and WAL is kept on another 150GB SSD with 2000 IOPS This article discusses the results of benchmark tests made using pgbench to test the performance of different versions of PostgreSQL on an instance of AWS m5.metal.

The LEGO Education WeDo 2.0 system is used in schools with a full curriculum to teach science skills, and is not as well-known or talked about in the LEGO fan community. The official LEGO MINDSTORMS website is an excellent resource for learning how to use the system, and you can find all the components under the LEGO MINDSTORMS section of the Online LEGO Shop. However, due to the large components and LEGO Technic parts the robots are quite dated and ugly looking (sorry, EV3!). LEGO MINDSTORMS is recommended for teens and adults for building a pretty much unlimited variety of sophisticated robots. LEGO MINDSTORMS is based on the LEGO Technic system, and includes various motors, sensors, and connectors that can be added to the EV3 Brick. At the heart of the product is the Intelligent EV3 Brick with a powerful ARM9 processor, a USB port for WiFi and Internet connectivity, a Micro SD card reader, back-lit buttons and four motor ports. The LEGO MINDSTORMS EV3 system is LEGO’s most advanced robotics kit used by both schools and individuals. You can find all the components under the LEGO Power Functions section of the Online LEGO Shop.
