The exact same argument could be said for COBOL and Fortran.

Probably not the Java stack itself, given GC latency and precision timing skew would translate into millions of lost dollars a second. However, people do silly things in the wrong languages all the time. =3

It looks like you're not up-to-date, ZGC has pauses on the microsecond dimension. Even since before ZGC was added, there are open source libs for HFT that optimize allocations to avoid GC: https://github.com/openhft =3

Indeed, it is likely some naive kludge like RTSJ

Tend to deprecate Java services for a number of other reasons =3

FWIW, I've seen job ads for Java developers in HFT.

It did look weird, of course, but they're also using Go (which iiuc has worse GC latency) or other garbage-collected languages (OCaml being a famous example).

The "heinous-dual-stack-blobs" joke refers to loading native binary objects in the JVM, but its probably some newer naive kludge like RTSJ.

I guess it is like using a Fiat Coupe as a gravel dump-truck. lol =3
