Wow. How big transfer are you trying with? Does using --trace and --trace-time
help you identify a specific part that runs slowly?

Does a -v run using both reveal any differences in how the transfers are being
made, ftp command wise?

Hi There,
I am in the process upgrading curl from version 7.19.6 to version 7.28.1 on our Solaris 10 servers. I have written a unix script to do file upload tests with ftp & sftp, and with different file types like binary and ascii (dos and unix).
With the script I noticed ftp uploads take about 2 to 3 times longer with version 7.28.1 compared to 7.19.6. sftp upload speeds seems to be ok.
Here is the technical details:
$ uname -a
SunOS M3000-dev-1 5.10 Generic_147440-25 sun4u sparc SUNW,SPARC-Enterprise
CURL latest version - slow with ftp uploads
$ curl --version
curl 7.28.1 (sparc-sun-solaris2.10) libcurl/7.28.1 OpenSSL/1.0.1c zlib/1.2.7 libidn/1.25 libssh2/1.4.3
Protocols: dict file ftp ftps gopher http https imap imaps pop3 pop3s rtsp scp sftp smtp smtps telnet tftp
Features: IDN IPv6 Largefile NTLM NTLM_WB SSL libz TLS-SRP
CURL older version - fast ftp upload speeds
$ curl --version
curl 7.19.6 (sparc-sun-solaris2.10) libcurl/7.19.6 OpenSSL/0.9.8x zlib/1.2.7 libidn/1.25 libssh2/1.4.3
Protocols: tftp ftp telnet dict http file https ftps scp sftp
Features: IDN IPv6 Largefile NTLM SSL libz
I will attach the script, it uploads 3x 250K binary files with sftp&ftp, 3x 25K ascii (dos & unix) with sftp&ftp
Let me know if you need more info
Thanks,
Daniel
