New Comment:
It is not related to this bug.
This bug was due to a wrong implementation, which was using RAND_Screen.
The "delay" here is not one per se and is relatively constant. Please open a
new
one for performance issue, there may have some ways to do not call the crypto
API everytime but to store a minimum amount of bytes per request (random size).
Move back to close.

It's a by reference parameter, not an option parameter.
I don't see the delay here on Win7 x64 with 5.3-dev

On 5.3.6, Win7 x64, and it seems on other windows versions as well, the call to
openssl_random_pseudo_bytes() still takes one second. Since apparently doing
non-crypto-safe output is not possible on windows, it would be great to at
least work on the delay for crypto-safe output.

Windows version?

The changelog says this has been fixed in 5.3.4, but the function still takes
1second to return on my machine (5.3.6). Note that the amount of bytes doesn't
matter, and it's always around 1second.
$t = microtime(true);
openssl_random_pseudo_bytes(1, $strong);
var_dump(microtime(true) - $t, $strong);
Outputs:
float 1.0317049026489
boolean true

Under CLI or inside a web server?
Can you try under CLI please?
