* Increase PERLIOBUF_DEFAULT_BUFSIZ to larger of 8192 and BUFSIZ.Craig A. Berry2011-02-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | The previous default size of a PerlIO buffer (4096 bytes) was chosen many years ago before PerlIO was even the default I/O scheme for Perl. Benchmarks show that doubling this decade-old default increases read and write performance in the neighborhood of 25% to 50% when using the default layers of perlio on top of unix. The only situation without a noticeable performance benefit so far appears to be when physical I/O is so slow that it dwarfs any savings from the reduction in layer shuffling, but there is also no performance penalty in this case. BUFSIZ will be chosen in the unlikely event that it's larger than 8192 on the assumption that the system maintainers would not set such a value without good reason. If the new size causes problems, or to try an even bigger size, configure with: ./Configure -Accflags=-DPERLIOBUF_DEFAULT_BUFSIZ=N where N is the desired size in bytes; it should probably be a multiple of your page size.

* Rename PERLIO_BUFSIZ to PERLIOBUF_DEFAULT_BUFSIZ.Craig A. Berry2010-11-101-2/+3
| | | | | | | PERLIO_BUFSIZ was already in use by Encode::Unicode for the PerlIOEncode_xxx layer, so it makes sense to specify that this macro is for the PerlIOBuf_xxx layer and that it is a default value that may eventually be settable at run-time.
* Make the buffer size for the perlio layer a macro.Craig A. Berry2010-11-091-0/+4
| | | | | | | | | | | The 4K buffer size was chosen way back in bb9950b. Significant performance improvements are seen with larger buffer sizes, though the optimum size likely varies by architecture and workload. For starters, we'll leave the default as-is but make the buffer size a macro and thus user-configurable via: sh Configure -Accflags=-DPERLIO_BUFSIZ=<number> Choosing a better (larger) default is still TODO.

| | | | | | | | | | English.t seems to fail on an errno test, and socketpair blathers about something. Basic fix is to stop PERL_IMPLICIT_SYS turning on USE_PERLIO by the back door, and instead have perlsdio.h vector stdio via iperlsys.h function tables (latter was done in earlier change).

| | | | | | | | | | | | | | | open($fh,">&STDOUT!") type code. - Invent PerlIO_openn() - which has "lots" of args a bit like do_openn() which is its main caller. In particular now has access to "extra" args, and can tell when an open handle is "reopened" (or duped?). - In -Duseperlio PerlIO_open() et. al. are now wrappers on PerlIO_openn(). - In -Uuseperlio (untested as yet) PerlIO_openn() is a wrapper on PerlIO_open() et. al. (i.e. other way round). - Collapse "vtable" entries for layers - was fdopen/open/reopen now just open with args close to PerlIO_openn(). p4raw-id: //depot/perlio@9302
