Default ioFTPD SSL Benchmark Tests

Machine:
AMD Athlon 1100Mhz
1GB PC133 RAM
Windows 2003 Advanced
On-board NIC (SiS 900)

Note: Pretty crappy NIC, I know, but the goal is just to see the speed difference between SSL and no SSL transfers, not measure the transfer speed.

Note 2: Added 40 bits encryption, which shows in FlashFXP as RC4 128 bits.

Results:

During SSL Transfers, CPU was maxed out by FlashFXP and ioFTPD:

Raw data:
http://mouton.abuserz.com/tests_ssl/results.txt
http://mouton.abuserz.com/tests_ssl/results.xls

Conclusion: SSL transfers using 128 bits encryption go about 53% of the speed of no SSL transfers.

so the client and server were on the same machine? a more accurate result would be to test with a true client connected via crossover or a good switch...the fact that the server has to do both the encoding and decoding skews the results and does not represent a real world scenario.

Conclusion: if you want performances .... forget SSL

big thx for these tests

When Ive saw Mouton's results ive decided to benchmark myself but this
time to a dedicated ioFTPD server running with 1,2ghz Duron, 768mb DDR,
7200rpm disks, KT400 Mainboard, D-link 10/100 NIC. I tested both upload
and download but there wasnt any difference in the speeds.I think there
is a big difference between my result and Mouton.


Require_Encrypted_Auth = *
Require_Encrypted_Data = *
Certificate_Name = xxxx
Explicit_Encryption = True
Encryption_Protocol = SSL3
Min_Cipher_Strength = 128
Max_Cipher_Strength = 384



Here ive tested 15mb file.

I might have done something wrong but I dont think so. I wasnt sure what Mouton got and his url is down. Ive tested to send from myself to myself with encryption(128bit) and got around 3mb/s.

I think he somehow bounced it through network.. so card was actually sending/receiving data which causes cpu load increase on cheaper cards
