CloudLinux allows restricting customers who use too much resources. You can set the limits in Cluster settings → CloudLinux limits.

LVE


Note:

LVE limits apply only to Apache processes when executing PHP or CGI scripts. Dovecot/Exim processes are not subject to limits.

LVE limits will be applied to users if individual settings are not specified. You can set individual limits when adding or editing a user. 

  • CPU load limit — in %. 100% indicates CPU speed relative to one core;
  • Total number of processes per user;
  • Physical memory — the maximum amount of physical memory that can be allocated to a user, in Mib. It includes shared memory used by the customer, as well as disk cache.
  • I/O limit — the maximum data throughput per user in Kbit/sec. It includes read and write operations; 
  • LVE concurrent connections — the maximum number of entries into LVE per user. 
Details

The limits are specified in /etc/container/ve.cfg.
