Esta informacion la tome del manual php:
I have written a script to highlight the superiority of shared memory storage.
Although it doesn't use the shmop function, the underlying concept is similar.
'/shm_dir/' is a tmpfs directory, which is based on shared memory, that I have mounted on the server.
Below is the result on an Intel Pentium VI 2.8 server:
IO test on 1000 files
IO Result of Regular Directory : 0.079015016555786
IO Result of Shared Memory Directory : 0.047761917114258
IO test on 10000 files
IO Result of Regular Directory : 3.7090260982513
IO Result of Shared Memory Directory : 0.46256303787231
IO test on 40000 files
IO Result of Regular Directory : 117.35703110695 seconds
IO Result of Shared Memory Directory : 2.6221358776093 seconds
The difference is not very apparent nor convincing at 100 files.
But when we step it up a level to 10000 and 40000 files, it becomes pretty obvious that Shared Memory is a better contender.
Este sujeto creo un programa que establece un segmento de memoria que es compartido.
El resultado final es que hay beneficios significativos cuando el script tiene que procesar cantidades inmensas de datos.
En resumen, la utilizacion de "Shared Memory" mejora u optimiza tu ancho de banda. Libera capacidad adicional de procesamiento.
Es medular lo que ha dicho Gpastor que el ancho de banda contratado NO
es modificable por el script pero su eficiencia si es modificable por el o un script debidamente diseñado.

Y espero ayude
