Yes, We Can Scale to 1,200 Concurrent Subscribers!

Yet again, I’ve doubled the number of concurrent Subscribers to 1,200 where each Subscriber is equivalant to a Windows Mobile device.  I used 6 servers running 200 Subscribers each to create client load, plus 3 load-balanced IIS servers, and a separate SQL Server Distributor and Publisher.  Each IIS server had its MAX_THREAD_PER_POOL registry setting set to 10 and had to handle 400 concurrent Subscribers.  With…

Believe it baby! Many of you have seen me at various Microsoft events during 2007 with my portable data center where I pushed the envelope of what’s possible with Mobile Merge Replication.  After synchronizing almost 14 million rows per hour between SQL Server 2005 and SQL Server Compact 3.1 at the Window Mobile Partner Summit,…

Chapter 1: Getting Started with Merge Replication

The non-linear fashion by which I’ve been writing this book reminds me of the way Pulp Fiction jumps around.  Chapter 1 is ready to go so you can get started with Merge Replication for Windows Mobile devices.  In addition to obvious technology walkthroughs, I also decided to add a bunch of scenarios that illustrate how mobile data synchronization can add tangible…

The biggest and most comprehensive chapter of the new book is ready to preview!  Chapter 3 is ready to go for some relaxing Labor Day weekend reading.  It’s the deepest coverage that I’ve seen on all the nuances of the SQL Server Publisher for mobile replication if I may say so myself. The book is…
