Can I optimize this on Android?

I found https cost more time on rust than java, then I found function verifyCertificateChain cost most time

CertificateVerifier.kt

            Log.d(TAG, "verifyCertificateChain PKIXBuilderParameters start")
            val parameters = PKIXBuilderParameters(keystore, null)
            Log.d(TAG, "verifyCertificateChain PKIXBuilderParameters end")

it cost 200ms every request

If change it, we can save time

                var trustAnchors = HashSet<TrustAnchor>()
                validChain.forEach {
                    trustAnchors.add(TrustAnchor(it, null));
                }

                var pkixParameters = PKIXParameters(trustAnchors)
                pkixParameters.certPathCheckers = listOf(revocationChecker)
                pkixParameters.isRevocationEnabled = false

                validator.validate(certFactory.generateCertPath(validChain), pkixParameters)

I have already try and it did work, so can we do this?

Start in CertificateVerifier.kt at verifyCertificateChain and inspect the PKIXBuilderParameters setup and subsequent certificate validation. Compare the proposed trust-anchor and PKIXParameters approach, then verify that certificate-chain validation remains correct while avoiding the reported per-request cost.
