Lets run through a hypothetical: Lets say you had a time machine, a very limited time machine that could only go back a microsecond and could only send information. Lets say you had a computer hooked up to this time machine. You ask the computer to find a number that you want, the number being 1100100 (binary for 100) the computer starts off at "1" this being the wrong answer sends back the message through the time machine to its self, lets say this takes 1 microsecond to make it clean (but horribly slow), after receiving the message from its self in the future it tries the number "10" (2), this being wrong it sends the message back and repeats the cycle until it reaches 1100100. If this was a normal (slow) computer it would have taken 100 microsecond to find my number but for the temporal computer would it have taken just 1 microsecond? Lets say the number I wanted was 1 trillion trilllion, it would still take just 1 microsecond to find? Lets say the number I wanted was infinity, would it still take just 1 microsecond to find? I would guess how long it would take is merely a matter of how much data it can send back, say it was 64 bits, as soon as the number being search for exceeds 64 bits would it now start taking actual time to find it? Assuming the amount of information it can send back per cycle is large enough, lets say I was running a virtual reality with a virtual me inside, every second of that reality is recorded and sent back the message received and the next second generated and repeat, would the me inside the virtual reality experience infinite time? Would Murphy's law come in and fuck it up?
