Informix vNext slides from IIUG/Scott/Karen/Shripad

Hi, Interesting IIUG talk from Scott/Karen/Shripad abhout vNext New Features https://www.iiug.org/wp-content/uploads/2023/04/Informix-VNext-New-Features.pdf "Performance better or equal than prior release: 14.10.xC1 Investigating new compiler impacts, better scaling on Linux, improvement of storage performance, …" I know Version 14 started using later compiler versions - https://www.ibm.com/docs/en/informix-servers/12.10?topic=notes-linux-x86-64 "This product was built on Red Hat Enterprise Linux ES release 5.3" https://www.ibm.com/docs/en/informix-servers/14.10?topic=notes-linux-x86-64 ""This product was built on Red Hat Enterprise Linux ES release 7.4"" I assume this is later compiler versions/more of using new compiler features as vNext does not support RHEL 7 but RHEL 8? But what is "better scaling on Linux"/"improvement of storage performance"? Does that include https://ibm-data-and-ai.ideas.ibm.com/ideas/INFX-I-440 "Evaluate using io_uring for I/O in Informix Linux Platform " As per https://gavinray97.github.io/blog/io-uring-fixed-bufferpool-zig io_uring has a fixed buffer mode where you pre-allocate and register a pool of buffers to use for I/O operations. Can this be looked at as part of io_uring?: Not sure if registering the whole of all bufferpool would be viable! Also storage performance could include: https://ibm-data-and-ai.ideas.ibm.com/ideas/INFX-I-525 "Support KAIO in cooked files using 4k formated disk for dbspaces with page size multiple of 4 " ??
