Varnish burns the CPU and eat the RAM

[thebog]

The storage you are assigning is the storage for objects, not memoryspace.

When it comes to how much memory Varnish uses, it's assigned by the OS.
There is a big difference of how much is uses and how much it's
assigned by the OS (normally). Use the top command and read the
difference between whats actually used and how much is reserved.

Read: http://www.varnish-cache.org/docs/2.1/faq/general.html for more
info around that.
In short, Varnish is using modern OS technics to find the "right"
balance, and therefore memory should not be an issue.

The burning of CPU is not correct, but I don't have any good pointers
there. Join the irc channel, and ask if someone there can help you
out.
