[curl:bugs] #1183 curl FTP upload performance degration version 7.28.1

Hi Daniel,
To sum it up in short, the one part of the test case uploads(ftp) 3 files using one connection to the ftp server. (Not one connection per file). All 3 files are 25KB in size.
I have run the trace and I determined 7.28.1 does a double "Checking for server connect", there is a second delay between the 2x "Checking for server connect" - this occurs for every file transferred.
See attached for full trace for both 7.19.6 and 7.28.1
Thanks,
Attachment: trace_7.28.1.txt (7.2 kB; text/plain)
--- ** [bugs:#1183] curl FTP upload performance degration version 7.28.1** **Status:** open **Labels:** performance **Created:** Thu Jan 17, 2013 07:15 AM UTC by Daniel Theron **Last Updated:** Thu Jan 17, 2013 09:35 PM UTC **Owner:** Daniel Stenberg 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 --- Sent from sourceforge.net because you indicated interest in <https://sourceforge.net/p/curl/bugs/1183/> To unsubscribe from further messages, please visit <https://sourceforge.net/auth/prefs/>Received on 2013-01-21 These mail archives are generated by hypermail. |
