Hi Bernhard,

could you test with a newer libcurl version? Fixed 100 ms delays always remind me of the Nagle algorithm and this might be related to and fixed by - even though I don’t have an explanation why it only happens when using GnuTLS. (Maybe OpenSSL sets TCP_NODELAY implicitly and GnuTLS doesn’t?)

Best Regards
