Sort of depends on your bike and run performances. If they were lacking, it may make sense to devote more time to those. I have heard from many people that you don't want to run too much, as you need to allow for recovery.

Straight from the top:

Did my first IM in 2004 and swam 1h07 on an average of 8km per week for the six months leading upto the race. I also did IMC 2005 and swam 1h05 on an average of 7km per week.

If you get your training down to 4km, you will finish in 59 minutes:)

At this point, relatively close to CDA, you may want to invest your time in cycling/running. If you are looking to improve in the long run, you should work on swimming more frequently, assuming you are only swimming 3-4 times per week.

It is a tradeoff and clearly, the largest gains are going to come from cycling. The focus on cycling will allow you to improve on the bike, and just as importantly, at a given effort, allow you to be less fatigued on the run.
