SoftEther in low bandwidth lines is very slow

[hyper]

hi

this software is very good & advanced but, in low speed lines like dial up or a 128 kbps line, is very very slow
i test it for web browsing, when without softEther , the page load is good but when i connect to softEther, pages loaded very slow :(
i tested it from my high speed server & another servers from vpnGate but, they are too slow

in high speed internet is very good and no problem

can i resolve this program? or need to fix it from developers?

somebody test SoftEther in low speed internet line from another countries?
is it slow or no problem?
