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

"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:

"Support KAIO in cooked files using 4k formated disk for dbspaces with page size multiple of 4 "
