Hi, I am trying to rollout a ruby agent in 32 bit and 64-bit Windows Server(s). What I am finding out is that the 32 bit system the agent works perfectly. In the 64-bit systems, the product works fine but the agent seems to take 24 % of the CPU of the server. Where as in a system similar but with 32-bit windows, the CPU usage maxes out at 1.5%. Is there a way to compile Ruby for 64-bit Windows? Has anyone seen this issue? Are there some tricks to solve this issue quickly? Thank you for anyone’s input in advance. Prakash ---

You would also need to compile every library and extension used by ruby to run in 64 bits. > Has anyone seen this > issue? No, using RubyInstaller daily in Windows 7 64 bits without these issues. ---

I am using Ruby 1.8.6 (2007-09-24 patch level 111). > How your script has been structured? It sit idle or performs any > routine or loops with sleep? Its running as a Windows service. It sleeps and wakes up every so many seconds and checks if there is anything for it to do. > > Is there a way to compile Ruby for 64-bit Windows? > > Don’t think that is the issue.

Installer works just fine. There are no errors, just the very predictable spikes on the 64-bit servers only. Any pointers even if they have not been validated would be very much welcome. Thanks.
