Hi there, I recently upgraded lftp from 4.2.2 to 4.6.5 and I noticed that FTPS slowed down quite a bit. I bisected versions and determined that the slowdown began at 4.5.0 and continues through 4.7.1. With 4.4.16 I'm peaking at 53 M/s downloads (with pget -n 5) with this server but with 4.5.0 I'm peaking at ~330 K/s (again, with pget -n 5) with the same file and server.
This isn't expected, right? I can't see anything in the debugging info that's different between 4.7.1 and 4.2.2 to explain the difference in speeds and I'm using the same options: set dns:order inet set xfer:clobber true set ftp:use-quit false set net:max-retries 3 set ssl:verify-certificate no set ftp:ssl-allow true set ftp:ssl-force true set ftp:ssl-protect-list true set ftp:ssl-protect-data true set ftp:ssl-protect-fxp true set ftps:initial-prot "" Any idea on things I can try to improve the throughput?
