Is it a good practice to pre-qualify contracts using ib.qualifyContracts() to be reused by any connections later?

[TianCal]

I’m building a latency-sensitive trading bot, and I already know the limited set of US stocks I will trade. All of them use contracts like: Stock(symbol, "SMART", "USD")

Would it be beneficial to call qualifyContracts() right after ib.connect() to reduce later latency when placing orders? Or is there something important that I’m overlooking?

If the answer to above is true, it seems like Contract object doesn't contain anything related to clientId, does that mean I can pre-qualify it with a random connection, disconnect it and reuse it later using any clientIds/connections?
