Zdravím všechny,

mám nainstalovaný Debian amd64 GNU/Linux 5.0 a v něm proxmox-ve-2.6.32 balíček a pve-kernel-2.6.32-4-pve.

Disky jsou rozděleny na /boot, / (soft mirror) a swap (soft strip). Zbytek je v ZFS strippu pro virtuálky.

Jde o to, že instalace a provoz VPS je děsně pomalý. CPU VPS serveru se fláká, nemá co dělat ale instalace VPS (např. CentOS či FreeBSD) je na celé dopoledne. U VPS jsem zkoušel ATA i SCSI disk, nicméně se to chová stejně pomalu - SSH spojení s VPS se trhá/zasekává...instalace balíčků trvá, atd..máte někdo radu, co kde pohledat? Je problém v tom, že pro virtálky není samostaný fyzický disk?

CPU: Intel(R) Xeon(R) CPU W3530 @ 2.80GHz
RAM: 12GB DDR3 SDRAM 1333Mhz
DISK: 2x 300GB4 SATA hard drive (10000RPM)
