We have been running Helix Server v6 for a while now but about two weeks ago we upgraded our main OS X server to Tiger on a new core 2 duo MacPro and decided to retire the little machine that helix was running on and consolidate services on one server. The collection that we are serving is about 52mb and we only ever have 4 or 5 clients connected at any given time.

Performance has been fine so far-- at least I have heard no complaints. My question is about the resources that Helix consumes. Helix has one of the four cores pegged at between 98 and 100 percent. No other service on the machine comes even close even though it is serving mail, three websites using php and mysql, and afp in addition to a now contact server and a few other services. In fact I just checked and Helix was at 98.9% and the next highest process was at 7%.

This isn't really impacting the server as Helix seems to stay on that one core. I am just curious as to whether this is normal. Is it related to rosetta? Memory usage seems a bit on the high side, but not outrageously so.

Anyway, just curious. This is 6.0.1 (65) by the way though (64) was the same.

Versions of Helix prior to 6.1 (tentative) take all free CPU time. As soon as another process requests CPU time, Helix yields, so this does not impact performance of other processes on the machine. The main downside is that it keeps the CPU humming at 100% and therefore consumes extra energy (creating more heat).
The reason this happens is obsucre, but we found and fixed it during the Xcode transition. As we release new Helix products built in Xcode, the problem will dissappear.
