I have tried Ubuntu software center to install FileZilla but, It does not installing showing me error either for connenction or other issue. If more memory is used by each connection, a fewer total number of connections can be established.Currently, I am working on Ubuntu 13.10 with 64 bit OS. The main issue is increased memory consumption. Is there side effects and if no why is not default value? For some reasons programs requesting a large TCP receive buffer actually get a smaller TCP window scale factor than programs not specifying a receive buffer at all. There can be considered as a Linux kernel issue. Other programs run well except Filezilla - why changing Linux and not Filezilla? The optimal value would probably be a number that's slightly higher than the largest bandwitdth-delay product you would ever encounter. Additional info What is the best value if the default is 212992. I am running on Linux Mint 17 and this worked for me. place the following lines at the end of that file:.run this command in order to edit file sysctl file (or vi, gedit -your favorite command).log as root (in terminal - CTRL + ALT + T check here: Useful Linux commands for beginners ).You can easily apply item by adding the commands to the end of your sysctl file.

This solution is a bit different but it works as well(tested).

execute this command - to show the current limits:.

Changing the version of Filezilla give a slight improvement on the results but still 10 times slower than Windows version.

I tested with Linux Mint 17 and Ubuntu 16 and the results were the same. My Filezilla was significantly slower comparing to windows equivalent.
