This was a chance to talk about other things I've been working on, such as the present and future of hardware performance. I also wrote about these topics in detail for my recent [Systems Performance 2nd Edition] book. Note that my predictions in this talk may be wrong, but they should be thought-provoking.

In this particular investigation, which spanned twenty months, we suspected hardware failure, compiler bugs, linker bugs, and other possibilities. Jumping too quickly to blaming hardware or build tools is a classic mistake, but in this case the mistake was that we weren’t thinking big enough.

It will also use less power than a two-socket Intel server, with a lower hardware cost, and potentially lower licensing costs (for things like VMware). This system has one AMD EPYC 7502P 32-core processor and 512GB of RAM. The price per QphH for this system is 0.34 The price per QphH for this system is 0.47

It comes set to SQL Server 2008 compatibility (level 100), but we will start with a more modern setting of SQL Server 2017 (level 140): ALTER DATABASE StackOverflow2013 SET COMPATIBILITY_LEVEL = 140 ; The tests were performed on my laptop using SQL Server 2019 CU 2. This runs in 115ms using the same amount of CPU time. Final Thoughts.

Table-valued parameters have been around since SQL Server 2008 and provide a useful mechanism for sending multiple rows of data to SQL Server, brought together as a single parameterized call. The DataTable can be created multiple ways in the.NET code, but a common way to create the table is something like the following: System.

A close monitoring of the hardware enthusiast community, including many of the most respected hardware analysts and reviewers paints an even more dire picture about Intel in the server processor space. This made it easier for database professionals to make the case for a hardware upgrade, and made the typical upgrade more worthwhile.

I always check backups first when looking at a new system. Prior to SQL Server 2012, the maximum server memory value only applied to the bufferpool, so customers needed to limit the amount of memory the bufferpool could use to save memory for the operating system and other processes. Memory settings. Statistics. Index maintenance.

Tech, and especially tech services, went counter-cyclical a few months into the last recession (2008). That capital, while being deployed now, is still jittery and remains at risk of systemic shock. There's been a sea-change in the technology sector, from counter-cyclical to pro-cyclical.
