Gurus, We do a lot of DSCOPYing here (thanks, HP, for continuing to support an alternative to the lowest-common-denominotor FTP!) and noticed that large transfers cause a lot of CM <-> NM switching. Being the kind of guy who likes to OCT things like that, but also the kind of guy who has a lot of respect for the nearly voodoo-like workings of HP networking software, I was wondering if anyone has gotten away with OCTing NFT.NET.SYS. If there are other portions of the networking suite which benefit from OCTing, I'd like to hear about them also. We're on 5.0, if that matters. Thanks in advance! Please e-mail me as our newsfeed lags sometimes and your response might get tossed 'cuz it's too old. I'll summarize the responses for everyone's edification.....
