The EPYC supports up to 384MB of L3 cache and the specs and benchmarks suggest the chiplet architecture can easily handle the I/O. > 10 years ago CICS was at 30 billion transactions per day, so > volume has tripled in 10 years, during the massive growth of cloud. > Healthy indeed. I have a different perspective on what constitutes healthy. Here in Australia, I've had the opportunity to meet architects from various banks who are actively involved in or have completed the process of migrating the read side of their CICS transactions to distributed systems. They have embraced technologies like CDC and streaming platforms such as Apache Kafka and distributed data stores such as Cassandra and MongoDb. This shift has been primarily driven by disruptive technologies like mobile banking pushing up mainframe software costs. This is a common architectural pattern. https://www.conferencecast.tv/talk-29844-nationwide-building-society-building-mobile-applications-and-a-speed-layer-with-mongodb#.talkPage-header > > On Mon, May 22, 2023 at 2:56 PM David Crayford<dcrayf...@gmail.com> wrote: > >> Sent again in plain text.
