Benchmarks
For a simple illustration of the speed up for reasonably sized streams, the following simple benchmark compares generating 1001 streams of integers and summing them with bc
.
First, generate a null delimited set of streams with
; do ; ; done
This stream is roughly 50M, making each stream roughly 50k.
I then piped this into xstream
as
|
and xargs
as
|
which on my system gives:
Program | User | System | Elapsed |
---|---|---|---|
xstream |
6.55 | 1.53 | 0:06.91 |
xargs |
17.26 | 3.98 | 0:18.01 |
This benchmark is a toy example, but xstream
already provides a 60% speed up when each stream is only 50k.
