For shared and reseller hosting the following CloudLinux (LVE) limits are in place. Please note these are default limits, and as with most things we are flexible and can change the limits to suit your needs.  In fact we often adjust these limits as needed at no extra charge:

CPU: 100% (AKA one CPU core)
Virtual Memory: 1GB
Physical Memory: 1GB
I/O: 6Mbps
IOPS: 3096
Entry Processes: 30 processes
Processes (NPROC): 100 processes
Inodes: 300,000

Please contact us if you feel the default limits are causing any issues with the performance of your scripts.
