Similar to other suggestions in this thread, If your -blocknotify execution is too slow, then create a solution that simply queues work. There is no need to add this code to bitcoind itself. Another solution is modifying pynode to directly listen to a trusted node (bitcoind), and monitor blocks as they arrive and are announced. That does not fix the problem of slow block processing on your side, but is another way to implement -blocknotify-like behavior. -- Jeff Garzik Senior Software Engineer and open source evangelist BitPay, Inc. https://bitpay.com/ ------------------------------------------------------------------------------ Get 100% visibility into Java/.NET code with AppDynamics Lite It's a free troubleshooting tool designed for production Get down to code-level detail for bottlenecks, with <2% overhead.
