Willy Tarreau	9ed560e964	BUILD/MINOR: silent a build warning in src/pipe.c (fcntl)	2011-10-24 17:09:22 +02:00
Willy Tarreau	bd9a0a7781	OPTIM/MINOR: make it possible to change pipe size (tune.pipesize) ... By default, pipes are the default size for the system. But sometimes when using TCP splicing, it can improve performance to increase pipe sizes, especially if it is suspected that pipes are not filled and that many calls to splice() are performed. This has an impact on the kernel's memory footprint, so this must not be changed if impacts are not understood.	2011-10-23 21:15:38 +02:00
Willy Tarreau	982b6e37e4	[MEDIUM] introduce pipe pools ... A new data type has been added : pipes. Some pre-allocated empty pipes are maintained in a pool for users such as splice which use them a lot for very short times. Pipes are allocated using get_pipe() and released using put_pipe(). Pipes which are released with pending data are immediately killed. The struct pipe is small (16 to 20 bytes) and may even be further reduced by unifying ->data and ->next. It would be nice to have a dedicated cleanup task which would watch for the pipes usage and destroy a few of them from time to time.	2009-01-25 13:49:53 +01:00
