[c-nsp] Extremely slow performing show running-config

[Jason Koh]

Hi there.

1. The time taken for show run is about 7-10 minutes long

2. #sh start
Using 67275 out of 391160 bytes
Can't really tell how much lines are there. It's a lot.

3. ROM: System Bootstrap, Version 12.1(11r)E1, RELEASE SOFTWARE (fc1)
BOOTLDR: c6sup2_rp Software (c6sup2_rp-PS-M), Version 12.2(18)SXD4, RELEASE
SOFTWARE (fc1)
System image file is "sup-bootflash:c6k222-ps-mz.122-18.SXD4.bin"

Using quite an old IOS I think. I just took over from the predecessor.

/Jason

Some questions:

  1. How long is "extremely long"
  2. How big (in lines and in bytes) is your startup config
  3. Which SUP, IOS version and linecards are you using
