Hi, guys:
Before, I run my win7 guest and centos7 guest on host debian 8 with virtualbox of version 5.2 and 6.0.0, it worked perfectly for years. My hardware: intel i5 4 core, 28G ram.
But few days ago when I upgraded my host to debian 9 kernel 4.9.0-11-amd64 and the virtualbox updated to version 6.0.12, it slow to the ground,
I running mysql in the centos vm, before I restarted mysql it take about 10 seconds, but now it take minutes, run one select script before it take 0.1 ms, now up to 30 seconds.
everything driving me nuts .
I have tried to decrease and increase the vms' cpus, ram, checked and disabled the 2D and 3D acceleration, actually I have never ever turned on it.
Now I give the win7 vm 6 processors 8G ram(before 8 processors 8G ram), and give centos7 4 processors 8G ram(before 4 processors 4G ram), but it make nothing change.
Anybody help me out.

Your CPU only has 4 cores available.
How did you manage to set more cores to the VMs?
You need to keep at least one core free for the host to handle a VM.
So any VM with more than 3 virtual CPUs will be very slow on your PC.

there is total 8 in the panel, mine is i5 4590, I don't know if it's per core two sockets. Anyway, I have figured it out already, thanks you..

That's wrong then. Actually you don't even have Hyperthreading:anleapat wrote:there is total 8 in the panel
And a visit to Intel's site confirms that. As Martin said, no more than 3, you're going to run into trouble, like slowdowns.00:00:01.689398 NumCPUs <integer> = 0x0000000000000006 (6) 00:00:02.416386 CPUM: Logical host processors: 4 present, 4 max, 4 online, online mask: 000000000000000f 00:00:02.416433 CPUM: Physical host cores: 4 00:00:02.416661 Full Name: "Intel(R) Core(TM) i5-4590 CPU @ 3.30GHz"

PS. For future reference you should ZIP your logs. It helps you, it helps us, it helps the server, it helps save a (virtual) tree or two...
