Performance tests (GZIP vs Brotli)

Proto schema

syntax = "proto3";
message uidCollection {
  message uidObject {
    string bidder = 1;
    string uid = 2;
    uint32 expirationOffset = 3;
  }
  uint64 expirationBase = 1;
  repeated uidObject uids = 2;
}

Results

• Used Protobuf + ${compressionType} + Base64
• Used uids of 70 length
