During the various courses I've been teaching, people are interested in how FILESTREAM performance compares with storing BLOBs in the database itself. I have some performance graphs based on measurements the dev team made - these have been presented publicly by myself and the dev team so I can share them with you here. There are three ...

Quickie today as I'm preparing to speak at the Pacific Northwest SQL Server User Group meeting tonight on the MS Campus here in Redmond (my trademark Detection and Recovery from Database Corruptions talk). SQL Server 2005 introduced the concept of hot-add memory, to allow for dynamic workload handling. SQL Server 2008 increases these ...

Back in September last year I blogged about the native Backup Compression that is in SQL Server 2008 (see here) and promised to blog more when CTP-5 came out and I ran some tests. Well, it's here and I have so here's some data for you. I expanded the AdventureWorks database to be 322Mb (random size, but big enough to get a decent ...

While we were in Barcelona we sat down with Richard Campbell and Greg Hughes from RunAs Radio to record a 1/2 hour interview on SQL Server 2008. We touch on a ton of different features (look at the number of Categories I've tagged this with!) and have a bunch of laughs along the way - check it out here. PS There's been a ton of ...

As I mentioned in a previous post, one of the new features for database mirroring in SQL Server 2008 is log stream compression. There's a good explanation of what this is (along with some example workloads and performance graphs) on the SQL Customer Advisory Team blog so I'm not going to duplicate all that here. Basically, ...

In SQL Server 2005, queries over partitioned tables use a single-thread per partition. This can cause performance problems under certain circumstances: On systems with many CPUs, if the table schema has less partitions than there are CPUs, then not all the CPUs will be used to process the query. Some examples: On a 32-way box, ...

Part of the improvements to Database Mirroring in SQL Server 2008 are the addition of 10 new performance counters under the Database Mirroring Performance Object. These add some cool troubleshooting capabilities. SQL Server 2005 provided the following 11 counters (from Books Online): Name Description ...
