Hi guys, I've installed Net::SFTP using CPAN (after some dependencies that were hard to resolve) on a CentOS 7 machine. I'm using this module to connect to a sftp server and upload a file. It looks it connects fine and after the upload starts it hangs or upload goes very slow. I have 2 use cases here: 1) If I press enter 2-3 times it goes further, closes connection but it looks only 65536 are transferred to sftp server. It looks files smaller than 65536 works fine. 2) to upload a 600KB file it took 12 minutes, see attached log basically the the sftp part took 12 minutes. <snip> ans667.int.example.com: sftp: Sending SSH2_FXP_INIT ans667.int.example.com: sftp: Remote version: 3 ans667.int.example.com: sftp: Sent SSH2_FXP_OPEN I:0 P:/sftptest/6672.pdf ans667.int.example.com: sftp: Sent message SSH2_FXP_WRITE I:1 O:0 ans667.int.example.com: sftp: In write loop, got 65536 offset 0 ans667.int.example.com: sftp: Sent message SSH2_FXP_WRITE I:2 O:65536 ans667.int.example.com: sftp: In write loop, got 65536 offset 65536 ans667.int.example.com: sftp: Sent message SSH2_FXP_WRITE I:3 O:131072 ans667.int.example.com: sftp: In write loop, got 65536 offset 131072 ans667.int.example.com: sftp: Sent message SSH2_FXP_WRITE I:4 O:196608 ans667.int.example.com: sftp: In write loop, got 65536 offset 196608 ans667.int.example.com: sftp: Sent message SSH2_FXP_WRITE I:5 O:262144 ans667.int.example.com: sftp: In write loop, got 65536 offset 262144 ans667.int.example.com: sftp: Sent message SSH2_FXP_WRITE I:6 O:327680 ans667.int.example.com: sftp: In write loop, got 65536 offset 327680 ans667.int.example.com: sftp: Sent message SSH2_FXP_WRITE I:7 O:393216 ans667.int.example.com: sftp: In write loop, got 65536 offset 393216 ans667.int.example.com: sftp: Sent message SSH2_FXP_WRITE I:8 O:458752 ans667.int.example.com: sftp: In write loop, got 65536 offset 458752 ans667.int.example.com: sftp: Sent message SSH2_FXP_WRITE I:9 O:524288 ans667.int.example.com: sftp: In write loop, got 65536 offset 524288 ans667.int.example.com: sftp: Sent message SSH2_FXP_WRITE I:10 O:589824 ans667.int.example.com: sftp: In write loop, got 29224 offset 589824 ans667.int.example.com: sftp: Sent message T:10 I:11 ans667.int.example.com: sftp: Sent message T:4 I:12 </snip> some recommendations for older versions was to use Math::BitInt::GPM which seems to speedup the process ... but it looks this module is not used anymore. even installing this it's not taken in consideration. Thank you.

This should be resolved in 0.12 which should be available on CPAN shortly. On Tue, Jun 27, 2017 at 6:39 AM, Ionut Hoza via RT <bug-Net-SFTP@rt.cpan.org Show quoted text

Hi Lance, I've updated to 0.12 and put function works as expected, also it seems a bit faster than in previous version. I think you can close it. Thank you, John. On Wed, Jun 28, 2017 at 1:06 AM, Lance Kinley via RT < bug-Net-SFTP@rt.cpan.org> wrote: Show quoted text
