We did some performance testing with downloading historical Intraday data. This is over a Wi-Fi connection. Approximately with version 2524 and higher, there is a change with how receive buffers are done with network I/O. This does not have any negative performance impact: With version 2524: HD Request # 44 | Received 66481991 Intraday data records from 2022-01-04 11:22:24.845000 to 2023-06-16 09:29:59.999000 (527.9 days. Delay: 34.2 days) and wrote 66481991 records for ESM23-CME | 2023-07-20 15:15:05.687
