But on a VPS server, the program outputs the first writeln line (not
even the consequent req.form printouts), then apparently stops for
several seconds ( 10 to 16) , and then suddenly starts working again. I
see this in the log outputs.
Why does this happen? How can I start debugging?
Before getting into it any further, try flushing output after every writeln.
This is true in D and C too -- if your `stdout` stream is connected to a
log file, it will *not* flush upon every newline. However, if it's
connected to a terminal, it *will* flush upon every newline.
It's possible it is running just as fast as you expect, but the buffered
output has not yet been flushed.
So just add `stdout.flush()` after every `writeln` call and see if it
helps. If not, then it needs more investigation.
