Hello everybody.

I have a problem with OSX that occurs in both my current pc as in the previous one, I always have been slow HD performance on HD. I mean slower than normal, watching the results of Xbench.

The fact is that this afternoon I booted osx, and repaired permissions. After that the Xbench results were:

Disk Test 70.34
Sequential 167.42
Uncached Write 180.22 110.65 MB/sec [4K blocks]
Uncached Write 167.33 94.68 MB/sec [256K blocks]
Uncached Read 131.03 38.35 MB/sec [4K blocks]
Uncached Read 211.19 106.14 MB/sec [256K blocks]
Random 44.52
Uncached Write 14.03 1.49 MB/sec [4K blocks]
Uncached Write 299.17 95.78 MB/sec [256K blocks]
Uncached Read 105.06 0.74 MB/sec [4K blocks]
Uncached Read 175.09 32.49 MB/sec [256K blocks]

My disc was working well for the first time!!!
BUT I made a big mistake installing some drivers for Midi, and I had to reinstall osx.

Now my HD is running as slow as usual:

Disk Test 13.51
Sequential 50.15
Uncached Write 45.32 27.83 MB/sec [4K blocks]
Uncached Write 23.80 13.46 MB/sec [256K blocks]
Uncached Read 139.75 40.90 MB/sec [4K blocks]
Uncached Read 117.49 59.05 MB/sec [256K blocks]
Random 7.81
Uncached Write 2.07 0.22 MB/sec [4K blocks]
Uncached Write 75.09 24.04 MB/sec [256K blocks]
Uncached Read 101.28 0.72 MB/sec [4K blocks]
Uncached Read 169.10 31.38 MB/sec [256K blocks]

Repairing permisions again no further help
Someone has an idea of what may be happening? Anyone can help me?

I'm really desperate
