The # modifications are: # # An increase in the KMEMSIZE parameter to about 4.2MB # An increase in the TCPRCVBUF parameter to 479232:786432 # An increase in the NUMFILE parameter to 3000 # # The file and buffers increases are needed to make apt-get # work correctly and the incease in kmemsize allows # dpkg to work. # # The increase in kmemsize would be a problem in a 32 bit machine # since all kernel memory is allocated from "low memory" or # ZONE_NORMAL and this is limited to a max of 860MB. However, # on a machine with 64bit processor(s) and AMD64 Linux all # 64GB of RAM is "low memory" so we have plenty. # Parameter format: # # The first number is the "barrier" and the second number is the "limit". # The barrier should never exceed the limit but the two often are # equal if the parameter in question requires then to be. # # Parameters with "guar" in the names are guaranters. # # Unit of measure for memory parameters is 4KB pages. So common # values are: # # 6144 = 25MB RAM # 12288 = 50MB RAM # 24576 = 100MB RAM # 49152 = 200MB RAM # 61440 = 250MB RAM VERSION="2" ONBOOT="yes" # UBC parameters (in form of barrier:limit) # Primary parameters # Average number of processes. The barrier should # be set equal to the limit AVNUMPROC="40:40" # Maximum number of processes and kernel-level threads # for this VPS. The barrier should be set equal to the limit. NUMPROC="65:65" # Maximum number of TCP sockets. The barrier should be set # equal to the limit. Although there are no direct limits to the # number of TCP sockets, the number needs to be controlled # because each socket uses some memory for rx and tx buffers. See # also parameters tcpsndbuf and tcprcvbuf. NUMTCPSOCK="80:80" # Maximum number of non-TCP sockets (local sockets, UDP and other types). # The barrier should be set equal to the limit. NUMOTHERSOCK="80:80" # Memory allocation guarantee. The limit of this parameter should # be set to the maximum memory in the machine. The docs say to set # it to MAX_ULONG, which is 2^32-1 (2147483647) on 32bit machines # and 2^24-1 (9223372036854775807) on 64bit machines. This # parameter is closely related to the privvmpages parameter, which # actually sets limits on the amount of memory available to the VPS. # The unit of measure is memory pages, 4kb on a 32 bit system and # unknown on a 64bit system. # # 6144 pages = 25MB RAM VMGUARPAGES="6144:9223372036854775807" # Secondary parameters # # All of these parameters are related to memory. For oomguarpages and # privvmpages units are in pages.

Each process consumes # at least 24KB but usually 30KB to 60KB. A very large process can # consume more. # # It is important to have a gap between barrier and limit. 10% is # a good minimum gap. To caculate the barrier, multiply the numproc # by 60KB (61440). To caculate the limit, add another 10%. # # This parameter is in bytes. KMEMSIZE="3892838:4282122" # The value of this parameter is related to numtcpsock and should allow # for 4000 bytes of memory per socket in the barrier.
