confirmTransaction is very slow

[Ismola]

This function in default-transaction-executor.ts runs very slow

const confirmation = await this.connection.confirmTransaction(
    {
      signature,
      lastValidBlockHeight: latestBlockhash.lastValidBlockHeight,
      blockhash: latestBlockhash.blockhash,
    },
    this.connection.commitment,
  )

I have the quick node RCP with the most expensive plan, but still, sometimes it takes up to 1 minute to confirm a transaction. I want response times in milliseconds. Any ideas?
