After change

After I added content filter for the custom maven url I got a faster build time. Here is how i did it

maven {
    url 'https://s3.amazonaws.com/salesforcesos.com/android/maven/release'
    content {
        // this repository *only* contains artifacts with group "com.salesforce.service"
        includeGroup "com.salesforce.service"
    }
}
