Dear Monks,

I have used IO::Socket::INET with good performance on the same machine, and now want to use it between 2 Linux servers. Both servers have GigE interfaces and the Ethernet cables are connected to a GigE managed switch. I tested using 'ftp' between both servers and can max out about 97% of the wire speed until the test 190+GB file is transferred in either direction. Great!

But when I use the Perl client/server model, I only get a maximum of 10Mbits, or the same as if I was using an old standard Ethernet set-up. The cores are using less than 3% of capacity, so the servers have plenty more horse-power if needed. Is this normal?

I using Perl 5.14.2 32bit on Debian 6.0.10 AMD 64bit. Both servers are the same hardware/software lookalikes. Has anyone seen this type of behavior?

Regards...Ed
