There is an interesting thread on the MSDN forums about WWF Scalability. The question was how many concurrent workflows can a single workflow instance handle. The answer was the number of .net threads available to the process the workflow runtime is hosted in. Which appearently is around 25 for a single proc box and 100 for dual. According to Srikanth there is even a value on the constructor of the DefaultWorkflowScheduler object, which recommended value for which is 20 on a single proc box.
Looks like I get to give my WWF presentation again to CINNUG. The talk will be given at this month’s meeting on Tuesday the 21st. I have a few updates from Beta 2 which I didn’t realize when I gave the talk the first time (but have since been set straight, thanks James Conard!), and I will have one or two additional slides that I just didn’t have time for in the seventy minute time window at the code camp.
Rob Bushway is giving away a DocuPen RC800! This is a pen scanner that can be used to scan entire documents in ~ 4 seconds. Instead of most pen scanners that scan a line of text at a time, this scanner is used to drag down the page and scan the whole document. All Rob is asking is that you leave a comment on his blog entry (this one here) stating how the pen would affect your digital lifestyle.
