Server load? murairo wepamusoro / CPU kushandiswa / mutoro wevhareji yekuverenga nzira

patinodzidza kushandisaLinux VPS server kukuvaka webhusaitiMushure meizvozvo, zvinodikanwa kuti unzwisise zvinorehwa neavhareji yekuremerwa yeakasiyana mavhareji emutoro, nekuti isu tinofanirwa kushandisatopIwo murairo unonzwisisa kupedzisa mamiriro ehurongwa uye unoteerera kune chaiyo-nguva shanduko yezvinosiyana.

Kuti unzwisise izvi, zvinodikanwa kuti unzwisise zvinotevera zvinotsanangurwa zvinosiyana.
