I have a new HDD an IBM 15GB, which is very slow. Each initial directory
access (cd, ls) takes a few seconds. Afterwards of course, it is
immediate. What could be the problem?
It doesn't just happen to large partitions or dirctories, it happens to
all of them. It doesn't happen with my old Quantum Bigfoot.
Details below.
Timing buffered disk reads: 32 MB in 5.76 seconds = 5.56 MB/sec
Timing buffer-cache reads: 64 MB in 1.60 seconds =40.00 MB/sec
[
Compare with the Quantum:
Timing buffered disk reads: 32 MB in 5.92 seconds = 5.41 MB/sec
Timing buffer-cache reads: 64 MB in 1.67 seconds =38.32 MB/sec
