Unity Performance Issue's

[sdawson35]

We have a Unity server running on Win2K it is its own domain and runs exchange.

Every 15 minutes or so the cpu use goes to 90+ percent, also it takes many rings to answer and thae actual voice playback is slow. The server is a HP DL380 G1 with 2.0 Gb memory, memeory usage is always at the 60 percent mark but goes high with cpu usage.

Hi -

I included the link to the supported platforms for Unity - http://www.cisco.com/en/US/customer/products/sw/voicesw/ps2237/products_data_sheet0900aecd802132ef.html

The G1 is pretty old, is that a 733 MHz CPU? Do you have just one CPU? I would really consider upgrading the server to meet the platform requirements (at least install a second processor). I would also use Performance Monitor to see what is peaking on your server every 15 minutes (i.e. Exchange, a Unity service, another service?) We run off-box message store so I cannot comment on experience with running Exchange and Unity on same server. One last thing, link to Performance monitoring for Unity 4.0(5) - http://www.cisco.com/en/US/customer/products/sw/voicesw/ps2237/products_maintenance_guide_chapter09186a0080443857.html#wp1075706

You didn't mention what version of Unity you are running or how many Exchange users you have for voicemail. That might help with additional info from other forum experts.
