Ambas herramientas son versiones multihilo del programa gzip, optimizadas para funcionar en sistemas de m\u00faltiples n\u00facleos. Crabz se diferencia en que est\u00e1 escrita en el lenguaje de programaci\u00f3n Rust, a diferencia de pigz, que est\u00e1 escrita en C (y, en parte, en C++), y muestra un aumento significativo en el rendimiento, que en algunos casos alcanza el 50%.    <\/p>\n<p>En la p\u00e1gina de desarrolladores hay una comparaci\u00f3n detallada de la velocidad de ambas herramientas con varias claves y backend utilizados. Las mediciones se realizaron en un archivo csv de 1.5 gigabytes utilizando como banco de pruebas un PC basado en el procesador AMD Ryzen 9 3950X de 16 n\u00facleos y con 64 GB de RAM DDR4, ejecutando el sistema operativo Ubuntu 20. Para aquellos que no desean profundizar en un an\u00e1lisis detallado del rendimiento, se ha preparado un informe breve:  <\/p>\n<ul>\n<li class=\"l\"> crabz con el backend zlib es id\u00e9ntico a pigz en t\u00e9rminos de rendimiento;\n<li class=\"l\"> con el backend zlib-ng es hasta 1.5 veces m\u00e1s r\u00e1pido que pigz;\n<li class=\"l\"> crabz con el backend rust es ligeramente (5-10%) m\u00e1s r\u00e1pido que pigz.  <\/ul>\n<p>Seg\u00fan los desarrolladores, adem\u00e1s de una mayor velocidad, crabz, en comparaci\u00f3n con pigz, tambi\u00e9n ofrece las siguientes ventajas:  <\/p>\n<ul>\n<li class=\"l\"> crabz con el backend deflate_rust utiliza un c\u00f3digo completamente escrito en Rust, lo que es m\u00e1s seguro;\n<li class=\"l\"> crabz es multiplataforma y es compatible con Windows, lo que puede atraer a m\u00e1s usuarios;\n<li class=\"l\"> crabz admite m\u00e1s formatos (Gzip, Zlib, Mgzip, BGZF, Raw Deflate y Snap).  <\/ul>\n<p>A pesar de su funcionalidad completa, crabz es descrito por el desarrollador como un prototipo conceptual de una herramienta CLI que utiliza el paquete crate GZP.<br \/>\n<br \/>Fuente: <a content=\"nofollow\" rel=\"nofollow\"
