I saw this private message today. Just a few words.

For ordinary people, like me, it's impossible to gain any advantage in performance or speed.
Order placement speed not only considers the program's performance but also network latency,
and your account level. Many exchanges intentionally delay ordinary accounts,
only accounts with special levels can be prioritized for order matching.
This kind of arbitrage that exploits speed advantages is generally called latency arbitrage.
It leverages the advantage of order placement speed.

So, ordinary people don't need to consider this issue when arbitraging.
Therefore, you can only approach it from other angles.
Perps arbitrage also doesn't require racing for speed.
Basically, the two sets of solutions from my previous open-source scripts
already meet the needs of most scenarios.
These two solutions do not require speed. You might even need to slow down,
to confirm whether the price difference truly reaches the threshold and remains stable,
so that the theoretical price difference and actual transactions align.
