Unfortunately, you provide very little information for the list to consider, only that you are using VS2008 and SFTP. I would suggest performing some more investigations on your part: - What libcurl version are you using? Did you build it yourself? - What SSL library are you using? What version? - Have you analyzed the network packets to determine the duration of each phase of the transaction? Where is the time being spent? - How does the performance of your application compare to the same SFTP transaction using a different client? - Finally, if it still looks like a libcurl problem, please let us know with as much information as possible. > Please get back to me ASAP. This is not the type of request that volunteers for an open source project like to see. We have real lives and jobs, too.
