Proxy.cfg [Object Cache] section

[dchunt]

In the [Object Cache] section of Proxy.cfg I have questions on two parameters:

cut thru no CLH length - The default is 51200 (Proxy Console #63) but Craig's Proxy.cfg sets it to 0. TID 10063926 talks about this but I wonder if this problem isn't fixed in NBM 3.9 SP1 and therefore doesn't need to be set to 0 now? Other TID's (10075563, 10069305 for instance) talk about setting it to 5120. What should be the correct setting for 3.9 SP1?

disk management factor - the default is 400 (Proxy Console #63) but Craig's Proxy.cfg sets it to 4000. Can someone tell me what this does and why it should be set to 4000 instead of 400?

thanks,

dan
