Unexpected Speed Limit, Linux Only
Posted: 2020-07-21 05:45
I use Filezilla on both Windows & Linux. They both run on the same PC (dual boot), same network, and both copies are configured identically (I actually copied the config files - i.e. sitemanager.xml, filezilla.xml, etc).
On, Windows I get the expected transfer speeds (i.e. 10-12MiB/s) - but on Linux, transfers always seem to behave as though they're capped at exactly 2MiB/s. If I copy 2 files in parallel, they each go 2MiB/s. I'm 100% certain that Settings->Transfers->Speed Limits is disabled ("Enable speed limits" is not checked). Yet for some reason, it behaves as though each connection has exactly a 2MiB/s speed limit. This speed limit is not being applied by the system - i.e. I can download files in Firefox significantly faster than 2MiB/s, so this behavior is unique to Filezilla.
Why would it be limiting transfer speeds like this, when the transfer speed limit is not enabled?
