I am using passing following options to submitPayment method

const txId = await kinClient.submitPayment(
    {
      sender: privateKey,
      destination: publicKey,
      type: TransactionType.P2P,
      quarks: kinToQuarks(kinAmount),
      invoice: {
        Items: [
          {
            amount: kinToQuarks(kinAmount),
            description: "kin spent or p2p",
            sku: new Date().getTime().toString(),
            title: "kin spent or p2p",
          },
        ],
      },
    },
  );

Hi. Thanks for submitting this issue. We think this is due to issues on the Solana end. They are taking a bit of a battering at the moment in terms of performance.

For context, we really want this to be over 2000:

We can see it's running way below the normal levels.

So what can be done related to this?
Do we need to raise issue with solana? If yes then where and how to generate issue with the solana?

Hi. It looks like this is something Solana is aware of and a fix is coming. Link for some context: https://twitter.com/aeyakovenko/status/1512551478883405834
