I'm not defending what DOGE is planning, but that statement about Java
is wrong. Maybe Java automatically generated from COBOL is 12 time
slower - that wouldn't surprise me - and I'd run a mile from having to
maintain if afterwards. But that doesn't apply to Java in general.
If you have Java code that is 12 times slower than COBOL I'm sure I
could rewrite it, probably faster than COBOL. (Assuming it's not
something that only runs for hundredths of a second - yes, the JVM
startup has overheads, probably tenths of a second these days).
I'm writing programs to process SMF data, and processing CICS records
runs up to about 1 gigabyte per second (uncompressed record size),
including decompressing the records in Java. Could you process 12GB/s in
COBOL? I doubt it.
I would say it's also easier to debug than COBOL, but that is probably
more a case of what you are used to.
