See the advice given in Net::FTP Upload much slower than Dos prompt command ftp and Net FTP Speed check and increase, or search for other nodes discussing this issue.	[reply]

Hi,thanks. But should I increase or decrease? from Net::FTP: BlockSize - This is the block size that Net::FTP will use when doing transfers. (defaults to 10240) these two posts say 'alter to 4096'.	[reply]

What happened when you tried changing it to the value specified in the two threads I linked to?	[reply]

Here, 10240 refers to bytes; hence, that's 1024K. "alter to 4096" means 4096K. I usually do a BlockSize of 8192K.	[reply]

Is your CPU used to 100% while running Net::FTP? Perl 6 - second systems done right	[reply]
