Why memory utilization on solaris always looks high?
You should post some factual figures like
prstat -Z and the already mentioned
mdb output to help figuring out how your memory is used.

I have statement about memory on solaris, is this true:
Memory in solaris is used for I/O cache, so if there is no memory in used, memory will be used by I/O cache. If the Application need memory, the I/O cache will release the memory.
This correct. However, note that this cache memory is reported as free memory if you are using UFS. ZFS cache is reported as used memory though.

If the "sr" value on vmstat > 300, there is bottleneck on memory.
There is no precise threshold. As long as the "sr" value stays at zero, you can be sure there is no pressure on RAM.
