Let's just look at cpu "power", not hyperhtreading or other factors.

Machine=IBM,9119-595 MHz=2102 Rounded-MHz=2100 CPUs=8
2100 * 8 = 16800

Machine=IBM,9117-MMB MHz=3108 Rounded-MHz=3100 CPUs=12
3100 * 12 = 37200

37200 / 16800 = ~2.212

So a priori, the 2.3 looks valid to me. I DO NOT know IBM architecture, but in Sun and HP boxes there are differences in the way cpus can be threaded, caching, bus throughput, disk vs SAN and so on which could give +/- values to performance.

Therefore, why do you suppose those numbers are not representative?

enum_ieee80211_channel_flags - channel flags SYNOPSIS
enum ieee80211_channel_flags { IEEE80211_CHAN_DISABLED, IEEE80211_CHAN_PASSIVE_SCAN, IEEE80211_CHAN_NO_IBSS, IEEE80211_CHAN_RADAR, IEEE80211_CHAN_NO_HT40PLUS, IEEE80211_CHAN_NO_HT40MINUS, IEEE80211_CHAN_NO_OFDM, IEEE80211_CHAN_NO_80MHZ, IEEE80211_CHAN_NO_160MHZ }; CONSTANTS
IEEE80211_CHAN_DISABLED This channel is disabled. IEEE80211_CHAN_PASSIVE_SCAN Only passive scanning is permitted on this channel. IEEE80211_CHAN_NO_IBSS IBSS is not allowed on this channel. IEEE80211_CHAN_RADAR Radar detection is required on this channel. IEEE80211_CHAN_NO_HT40PLUS extension channel above this channel is not permitted. IEEE80211_CHAN_NO_HT40MINUS extension channel below this channel is not permitted. IEEE80211_CHAN_NO_OFDM OFDM is not allowed on this channel. IEEE80211_CHAN_NO_80MHZ If the driver supports 80 MHz on the band, this flag indicates that an 80 MHz channel cannot use this channel as the control or any of the secondary channels. This may be due to the driver or due to regulatory bandwidth restrictions. IEEE80211_CHAN_NO_160MHZ If the driver supports 160 MHz on the band, this flag indicates that an 160 MHz channel cannot use this channel as the control or any of the secondary channels. This may be due to the driver or due to regulatory bandwidth restrictions. DESCRIPTION
Channel flags set by the regulatory control code. AUTHOR
