[LRUG] rib / gem etc slow to start

Anyone come across irb / gem etc commands being very slow to start to the order of 2 to 5 seconds? 

rlivsey at app2:~$ time irb -v 
irb 0.9.6(09/06/30)
real 0m2.980s
user 0m2.635s
sys 0m0.344s

rlivsey at app2:~$ time gem -v
1.8.23
real 0m3.387s
user 0m2.862s
sys 0m0.523s



Ruby itself is quick:

rlivsey at app2:~$ time ruby -v
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux]

real 0m0.147s
user 0m0.072s
sys 0m0.076s


This is on a new Linode box running Ubuntu 10.04 LTS 64bit, 2GB RAM. Ruby is freshly compiled from source with ruby-build, so not lots of gems or anything like that.

Just updated rubygems to see if that did anything, no real effect there:

rlivsey at app2:~$ time gem -v 
2.0.3
real 0m1.660s
user 0m1.394s
sys 0m0.267s




On another Linode box I'd previously setup I get expected times:

rlivsey at app1:~$ time irb -v 
irb 0.9.6(09/06/30) 

real 0m0.233s 
user 0m0.184s 
sys 0m0.050s 

rlivsey at app1:~$ time ruby -v 
ruby 1.9.2p180 (2011-02-18 revision 30909) [x86_64-linux] 

real 0m0.010s 
user 0m0.005s 
sys 0m0.005s                                              



Cheers.
