I read the whole report, and pretty much everything says that while things are bad for Obama, they were just as bad if not worse for GW Bush:
Length of Time from Nomination to Confirmation
Overall, President G.W. Bush's circuit court nominees who were confirmed during his first term waited, on average, the longest period of time from first nomination to confirmation (277.0 days). President Obama's nominees waited, on average, the second-longest period of time (240.2 days).
Length of Time from Nomination to Committee Hearing
Figure 3 shows that circuit court nominees of President G.W. Bush waited more days to receive a hearing than did the nominees of the other four Presidents. The mean and median number of days for a circuit court nominee to receive a committee hearing after being nominated ranged from a low of 28.7 and 16.5 days, respectively, during the Reagan presidency to 274.6 and 172.5 days, respectively, for the G.W. Bush presidency.
Where Obama has gotten slammed, in comparison to all other Presidents, is mean and median number of days from Committee Report to Confirmation, which is controlled by none other than Harry Reid, who controls the Senate Executive Calendar and brings candidates to vote:
The median number of days for President Obama's 30 confirmed circuit court nominees is 131.5, 7.3 times greater than the median number of 18 days for the 35 confirmed circuit nominees of his immediate predecessor, President G.W. Bush.
Before the knee-jerk reaction of "well, this shows filibustering", you should know that the median number of days for unopposed candidates (zero nay votes in committee or on the floor) skyrocketed because of Reid's reluctance to bring them to a vote:
Table 4 shows that, for circuit court nominees who had zero nay votes cast against their nominations, that the average and median number of days from committee report to confirmation was greatest during President Obama's first term (i.e., greatest during the 111th and 112th
Congresses). Such nominees during President Obama's first term waited, on average, for 124.7 days on the Executive Calendar prior to being confirmed (compared with 16.9 days during President Clinton's first term and 29.3 days during President G.W. Bush's first term).
