Here is what I experienced. Perhaps someone will have some idea about why this happen. I installed (unpacked) the system on the 20GB 7400RPM HD that came with the Qube 2 yesterday. I used method described here http://www.cyrius.com/debian/cobalt/no-serial.html. After that I replaced the kernel with the one that supports serial terminal. After booting the drive I did a read and Write test on the disk. I first created a large file by running:
cat /proc/kcore > big_file Running that for a 50 sec or so created a ~1GB file on the drive. After that I tested the reed speed by running: time cp big_file /dev/null That, I think, would just read the file and dump it into nothingness. Amazingly I got about 18MB/sec reed speed, and comparable write speed. Further, I did a disk to same disk copy of the file and got a reasonable 4.43MB/s. (not grate, but ok) After system update however, and installing samba, doing the same test resulted in under 3MB/sec read to null test and little less then 1MB/sec disk to same disk copy. I am not sure what happen. I am going to run through this again perhaps tomorrow and do the reed/write speed test after each step. I am not sure why this is happening, but it looks like the qube is not all that slow, as I confirmed that original reed test 3 times at the time (I was stunned because it outperformed my scsi array on the initial test). I also experienced very, very slow SAMBA transfer speeds. As slow as 700KB/s reed and write. My network is 100Mb/s, and as far as I know qube 2 should support 100Mb/s. I have the Qube 2 with 64MB of RAM. I appreciate your help alot. If you get any ideas, please let me know. Thank you, - Bogdan
