You could try to move the metadata creation in front of the loop, memory allocation in a tight send loop could result in a performance loss. Other than that the code looks good. Sending data in bigger chunks would certainly improve the performance. Cheers, Andrej -- Andrej Rode GPG Key: 750B CBBB 4A75 811A 4D5F 03ED 5C23 7FB8 9A7D A2AA
