Centos 7 on MacMini7.1

Post by gfca » 2019/09/20 10:36:45


I installed Centos 7.5 on MacMini 7.1 (2014).
MacMini has an Intel core i7 (3ghz) and 16 GB ram, and my SSD is APPLE SSD SM1024F 1.0 TB.

All went good, and after my installation I updated to "CentOS Linux release 7.7.1908 (Core)" with success.

Now, I started to use the system and start to notice that some operations are very slow!
Installing the package "webadmin" (20MB) it took me about 7 minutes - only installing! (not counting the download time because that was fast).

I don't know if it's missing some option or tweak, but i can't find more info about this problem.

Also, i still have the MacOS in this MacMini, and it runs very fast. So it's not an hardware problem.

I run the getinfo.sh script:

Also doing the hdparm test:

Code: Select all

 Timing cached reads:   18450 MB in  1.99 seconds = 9263.59 MB/sec
 Timing buffered disk reads: 2276 MB in  3.00 seconds = 758.37 MB/sec
Has anyone had the same problem?
Someone can give me some thoughts about this problem?

Thanks a lot!

Meanwhile, i noticed that CPU speed is at minimum values:

Code: Select all

model name      : Intel(R) Core(TM) i7-4578U CPU @ 3.00GHz
stepping        : 1
microcode       : 0x25
cpu MHz         : 799.987
I had to execute

Code: Select all

cpupower frequency-set performance
to put 3000 MHz.

But it continues with some (slow) problem that i could'nt find yet!

Still searching...

You can always check the SSD with 'smartctl -a' to see for any errors.
Can you paste the device name ?
