Subject: [PATCH 1/2] constant size for bench.php

i don't like the previous behaviour where the bytes to hash change every time the code change,
that may make it difficult to compare hash() performance changes over time,

as a recent example, Nikita's commit from 2020-10-26 changed the bytes to hash from 2240 bytes to 503 bytes.. ( e0ea3e8a0180ec86e3c5da80e4a0bf5b12dea84d )

Subject: [PATCH 2/2] nice round number + argv[1]

quote:
@nikic
I don't think there's any point in preserving the exact previous size. Let's make this a nice round number like 2048. Could also make it $argv[1] ?? 2048 to allow passing a different size :)
