I just tested bumping up the receive buffer size from 8192 (0x2000) to 524288 (0x80000) bytes and saw times drop from ~65sec to ~15 sec. The socket takes just a few millis to respond but it looks like the processing of that payload is what’s taking time (example below). Not a lot (15 or so millis per chunk) but that’ll add up when you’re dealing with ~2500 vs ~200 chunks. [17/04/11@11:34:46.800-0400] P-001156 T-016324 1 4GL LogMgrWrtr [O.Net DEBUG] ReadHandler: OK?
