Then let's assume the Duron uses SDRAM and the P4 DDR. SDRAM CL2 on crappy VIA chipset can handle ~1000MB data per second and regular DDR memory also on VIA chipset can easily handle 2000MB/s (SiSoft Sandra mem benchmark).
Then let's assume performance in the test above is very memory speed dependent - we double the Apache values. ioFTPD would still have twice the amount of transactions, five times higher throughput and still higher transaction rate.
Conclusion: ioFTPD is still faster.
