Why is network speed so very slow on PS2

[superfrog12]

Hello,

Why is the transfer speed from PS2 to PC so very slow in program like ftp and also other? is it because of some limitation in PS2 hardware or is it because of unoptimized tcp/ip stack? if so, what is the bottleneck, do you know?

thank you

Hello,

In most cases it is due to unoptimized programming, which can be distributed over both the high-level main application (such as the FTP server for PS2), and the IRX modules such as the low-level ethernet hardware driver and the TCP/IP stack driver.

It is interesting to note here that the "host:" device driver implemented 'on top of' the TCP/IP stack is in fact much faster for transfers in either direction than any of the FTP server implementations of the PS2 ever were. This is especially so when using the improved network modules that EEUG developed for SMS.

For most PC-PS2 transfer needs I recommend using uLaunchELF and its "host:" device at the PS2 end with PS2ClientLoader + PS2Client at the PC end. Just remember to activate the HOST ability for writing data on the PC by changing "NET_HOSTwrite = 0" to "NET_HOSTwrite = 1" in your LAUNCHELF.CNF file.
