Minimum advisable for LRU_MIN_DIRTY

Hi. I deal with an IDS 9.40 FC7 under Solaris 9 transactional installation with LRU_MAX_DIRTY = 2 and LRU_MON_DIRTY = 1, and 950000 in BUFFERS. Even when cleaners starts very soon, my checkpoints use to be as big as 50 seconds during peak hours (I've tried to increase or decrease checkpoint interval with no success, nowadays I assign 4 minutes). I'm wondering if setting LRU_*_DIRTY to 1 and 0 would work, or if it's possible to set values as 1.5 and so on. Let me add that the working environment is OLTP, but a lot or writes may happen very often, operations that write in average 50 Mb on logical logs in 4 minutes. Is my approach correct, or should I try a different point of view? Thanks in advance.
