ruby OCI8缓慢初始化

Question

I'm developing API for product based on Oracle database and I tried to use ruby-oci8 gem, but I faced a strange problem - OCI8.new is very slow, it takes 1,2-1,5 second to connect to database.

For example:

~ mmulev$ irb
2.1.1 :001 > require 'oci8'
 => true 
2.1.1 :002 > def test
2.1.1 :003?>   t0 = Time.now
2.1.1 :004?>   OCI8.new('SCHEMA', 'STRONG_PASS', '//db_host:port/service_name')
2.1.1 :005?>   Time.now - t0
2.1.1 :006?>   end
 => :test 
2.1.1 :007 > test
 => 1.217809 
2.1.1 :008 >

The same thing in php (oci_new_connect) needs approximately 0,1-0,2 second to establish connection and return handler.

Is there any other solutions besides connection pooling?

PS ruby API code was profiled by method_profiler and by Benchmark, oracle v - 11g
