I'm sure this delivered large performance improvements and I wouldn't try arguing against it. 2005-2023: The winter of broken profilers However, the change was then applied to x86-64 (64-bit) as well, which had sixteen registers and didn't benefit so much from a seventeenth.

Simple parameterization has a number of quirks in this area, which can result in more parameterized plans being cached than expected, or finding different results compared with the unparameterized version. Reputation = 252552 ; These statements result in six cached plans, three Adhoc and three Prepared : Different guessed types.

Both target performance and efficiency for workloads frequently submitting simple statements. In this first part, after a quick introduction, I look at the effects of simple parameterization on the plan cache. The aim is to reduce compilations by increasing cached plan reuse. Simple Parameterization. Shell Plans. sp_configure.

This was a keynote presentation at the “2nd International Workshop on Performance Modeling: Methods and Applications” (PMMA16), June 23, 2016, Frankfurt, Germany (in conjunction with ISC16 ). Here I assumed a particular analytical function for the amount of memory traffic as a function of cache size to scale the bandwidth time.

It includes initializing each operator, and adding hidden profilers to collect runtime performance data like actual row count and elapsed time. The fundamentals of row mode parallel execution haven’t changed since SQL Server 2005, so the following discussion is broadly applicable. Compatibility level 150 is used exclusively.
