file queuing in 3.45 is much slower than in 3.6

#1 Post by johnwayne__ » 2019-10-11 02:14

i recently installed 3.45 and thought the queuing seemed slow. so i did a queue all of my server and timed it, repeated this several times. it consistently took about 30 minutes to queue it all. i uninstalled 3.45 and installed 3.6 (oldversion.com) and ran same test. 3.6 consistently queued it all in about 20 minutes. a 10 minute slowdown to perform a single site download is awful. can some settings be changed to get the 3.6 queuing speed out of 3.45?

Are you using the same protocol in both versions? Note that 3.6 is insecure, it does not default to FTP over TLS.

good catch, i was using plain FTP in 3.6
it's a shame that the cost of security is 10 minutes per my average site X 200+ sites.
I understand that the handshake of security is more involved causing a slower initial connection, however the slowdown must persist throughout the interaction with the server once logged in (which i did not realize).
are there any apples-to-apples comparisons of the speed of the different protocols? perhaps my webhost can provide some other connection than 'explicit FTP over TLS'.

The data connections too require handshakes, one for each new transfer.

In any case, handshake performance depends a lot on the used handshake algorithm.

If you connect to your server using FIleZilla and then click the lock icon in the status bar, what does it list as TLS version and key exchange algorithm?
