While this may not seem significant for websites with low traffic, as traffic to the site begins to increase, so does the amount of energy consumed. CPU Utilization and Power Consumption (Source: Blackburn 2008). Server Power Consumption (Source: Intel Labs 2008). Unfortunately, that’s not where it ends.

SQL Performance

JANUARY 22, 2020

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.

The presentation discusses a family of simple performance models that I developed over the last 20 years — originally in support of processor and system design at SGI (1996-1999), IBM (1999-2005), and AMD (2006-2008), but more recently in support of system procurements at The Texas Advanced Computing Center (TACC) (2009-present).

It uses a Solaris Porting Layer (SPL) to provide a Solaris-kernel interface on Linux, so that unmodified ZFS code can execute. There's also a ZFS send/recv code path that should try to use the TASK_INTERRUPTIBLE flag (as suggested by a coworker), to avoid a kernel hang (can't kill -9 the process). LTS (April 2016).

Tool 1: Dolly the Sheep Companies that are heavily rule-based - think insurance - eagerly moved their business rules into code. It was easy to move into code; it's just as easy to move it back into human-readable format. A clone of something extinct - our lost business knowledge - runs the risk of suffering severe defects.
