@Piru: sorry for the delay. Had to assemble my test machine again.

First test on Blizzard 4030@50MHz:
Code: [Select]

BusSpeedTest 0.19 (mlelstv)   Buffer:     262144 Bytes, Alignment: 32768
========================================================================
memtype   addr       op         cycle     calib         bandwidth
user      $50000000  readw     255.8 ns   normal       7.5 * 2^20 byte/s
user      $50000000  readl     430.3 ns   normal       8.9 * 2^20 byte/s
user      $50000000  readm     415.0 ns   normal       9.2 * 2^20 byte/s
user      $50000000  writew    331.4 ns   normal       5.8 * 2^20 byte/s
user      $50000000  writel    331.5 ns   normal      11.5 * 2^20 byte/s
user      $50000000  writem    289.6 ns   normal      13.2 * 2^20 byte/s


Second test on CSPPC 060@50MHz:
Code: [Select]

BusSpeedTest 0.19 (mlelstv)   Buffer:     262144 Bytes, Alignment: 32768
========================================================================
memtype   addr       op         cycle     calib         bandwidth
user      $50000000  readw     631.5 ns   normal       3.0 * 2^20 byte/s
user      $50000000  readl     632.7 ns   normal       6.0 * 2^20 byte/s
user      $50000000  readm     632.7 ns   normal       6.0 * 2^20 byte/s
user      $50000000  writew    362.2 ns   normal       5.3 * 2^20 byte/s
user      $50000000  writel    362.8 ns   normal      10.5 * 2^20 byte/s
user      $50000000  writem    362.8 ns   normal      10.5 * 2^20 byte/s


Values are in real megabytes (2^10 bytes = 1kB), not in "HDD" megabytes (10^3 bytes = 1kB).
