Hi,

Please advise if this is the correct place to post this question.

I am testing NetBSD 1.6.2 on a P3 1G, 512M memory

I find that mfs, memory file system is significant slower than my old
6G harddisk. Please advise.

using MFS,

bash-2.04# ./Bonnie -d /etc/dnscache/log/main/ -s 10
File '/etc/dnscache/log/main//Bonnie.5474', size: 10485760
Writing with putc()...done

Writing intelligently...done
Reading with getc()...done

Seeker 1...Seeker 2...Seeker 3...start 'em...done...done...done...

9496.9 92.2

using FFS on 6G old seagate harddisk. This is really old 5400rpm type of 
harddisk.

bash-2.04# ./Bonnie -s 10
File './Bonnie.5478', size: 10485760

3713.0 19.9

Any reason why it is so ? please advise.
