Test data of PostgreSQL running on FreeBSD and Linux
This afternoon I wanted to test DragonFly dports. I suddenly wondered why I didn't compare the performance difference between PostgreSQL in BSD and Linux. For this reason, I set some standards to compare the performance differences on different operating systems. I use the same hardware and software to obtain data more accurately. These tests are based on PGSQL9.1.
After I tested it In Debian Linux, I was surprised by the results. So I did a
Three cores is simply 3 cores, the core is also called the kernel, is the CPU most important component.
The three nuclear products were first developed by AMD.
When AMD suddenly announced that it would launch its primary tri-core processor phenom Tripe-core in the first quarter of 2008, the entire industry felt somewhat unprepared, after all, the focus was on 1-2-4-8-16, a double core growth model. With Intel's aggressive push on the hard way for se

Intel uses a unified scheduler in the Core/nehalem microarchitecture to handle all instructions, whether integer or floating-point, and the AMD Bulldozer architecture separates them. AMD says that each bulldozer module has a floating-point scheduler, supplemented by two 128-bit Fmac, and each thread allocated to the core can use any one FMAC unit; if one thread is a pure integer, the other can take a

And the FSB has to transmit I/O data and memory data at the same time, so the qpi available bandwidth is higher.QPi is faster than HyperTransport. The current hypertransport can reach a maximum speed of 10.4gb/s, but the current phenom processor can only reac

The difference with direct conversion is that only the A-Z, a-z range of characters conversion, there are some limitations, but in most scenarios is available, and the efficiency is good enough.

Note: To get a more accurate score, it is best to open only one test window and close all other windows or labels during the test.
