Of course writes were much less common than reads, so I added a caching layer for reads, and that did the trick. Then in 2008, Google issued a code yellow for application speed, and I was the code yellow lead for Google Docs.
However, unlike the early days of the web, static sites are no longer limited to developers working in a code editor. Piecing together a website using a WYSIWYG editor and seeing the code it generated was a fascinating and educational experience that sparked an initial interest in web design. Editing a blog post in MovableType 2.0
Now we have a problem statement that we can reason about: why are large chunks of our code segment filled with zeroes? This command compares the code bytes in the crash dump (some of them are saved in the crash dump, just in case) against those on disk. In this case it said that 9322 bytes in the code in the crash dump were wrong.
Without effective caching on the client, the server will see an increase in workload, more CPU usage and ultimately increased latency for the end user. CPU Utilization and Power Consumption (Source: Blackburn 2008). Server Power Consumption (Source: Intel Labs 2008). This is where service workers can make a difference.

SSRS 2008 brought that component into the reporting service module. Caches of report results are stored in the ReportServerTempDB database and I/O performance can become an issue here. To tune for a slow report, that usually means you need to create indexes for that specific report or tune the code within the report.
I happen to be using SQL Server 2019 CU16 but the details I’ll describe haven’t materially changed since partition level lock escalation was added to SQL Server 2008. SET NOCOUNT , XACT_ABORT ON ; -- Prevent plan caching for this procedure. -- See [link]. Notice the lack of a check at 1250 due to the code quirk I mentioned.
It can be activated from SQL Server 2008 to 2014 inclusive using documented trace flag 610. The FastLoadContext code path adds support for minimally-logged and concurrent bulk load on: Empty and non-empty clustered b-tree indexes. There are two main code paths that can set DMLRequestSort to true for index inserts. The sqllang!CUpdUtil::FOptimizeInsert
In hindsight it’s obvious that these zombies were caused by a trivial user-space coding bug. If you do care – if you want to wait for the process to quit – WaitForSingleObject(hProcess, INFINITE); – or query its exit code – GetExitCodeProcess(hProcess, &exitCode); – then you need to remember to close the handles after that.
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).
“SQL Server 2016 running on the same hardware as SQL Server 2014, 2012, 2008, 2008 R2 or 2005 uses fewer resources and executes a wide range of workloads faster. The following table is taken from an ASP.NET, session state cache, stress test. ” – Bob Dorr, Principle Engineer SQL Server Support. .”

MariaDB is a popular SQL open source relational database management system that originated as a fork of MySQL after MySQL was acquired by Sun Microsystems in 2008 and later Oracle in 2010. In 2008, Sun Microsystems acquired MySQL AB, and then, in 2010, Oracle bought Sun Microsystems. What is MariaDB? release based on MySQL 5.5,
My goal is to resolve mysteries about SQL Server I encounter but do this without going straight the source code first. c:public_symbols is a symbol cache and a folder I created on my laptop. I used the k command to dump out the call stack to see where in the code it hit this API call (not the full stack but enough to see the story).
