Benchmark results of Epyx Fastload, Final Cartridge III+, SD2IEC Kernal, ExOS v3 and JiffyDOS, which all supported by SD2IEC, are as follows:

Test file: 149 blocks, 37631 bytes, loads between $0801-$9b00.

The time spent to load the test file:

Normal: 75 seconds
Final Cartridge III+: 5.6 sec.
ExOS Kernal: 5.5 sec.
SD2IEC Kernal: 4.9 sec.
Epyx Fastload: 4.7 sec.
Jiffy DOS: 3.7 sec.

Rounded loading speeds in Bytes/sec.:

Normal: 500 bytes/sec.
Final Cartridge III+: 6700 bytes/sec.
ExOS Kernal: 6800 bytes/sec.
SD2IEC Kernal: 7700 bytes/sec.
Epyx Fastload: 8000 bytes/sec.
Jiffy DOS: 10150 bytes/sec.

Timing:

I used CIA 6526's TOD clock as a clockwatch.

Preperation:

poke56590,136:pO56587,0:pO56586,.

Loading and timing (commands are shortened to fit into 80chars):

pO56585,.:pO56584,.:pO631,13:pO198,1: ?"?pE(56585)pE(56584)":lO"test",8

Note: CIA's TOD keeps time in binary-coded decimal format.
