hello all and thank you for your time.

I'm sure this is a popular question but I have recently just implemented a new 2010 exchange server and it has xenon processor 2.4 ghz with 8 gigs of ram.  I have about 20 mail box users.  I noticed that by the end of a day or two after I restart that it is RAm hungry.  the store will eat up almost a gig or more of ram.

is there any performance tricks or anything I should look at to combat this high ram usage.  the server gets up to 95 % ram usage and it begins to slow down.  nothing major but a couple f boxes will receive emails on a delay.

Will depend on Exchange roles and size/load on mailboxes - see: http://technet.microsoft.com/en-us/library/ee832793.aspx

the information store will always reserve as much memory as possible for ram access is faster than disk access so it does this for performance and this is normal behavior

yes but when it reaches 95% usage it effects sending and receiving mail.  its on a delay because its caching everything

well users are stating that when sending emails that an email will sit in the outbox for a longer than usual period of time.  normally emails just zip out of the outbox and they are sent.  it could be a minute or so before it actually leaves the outbox

once thing I have noticed is that if you hit the send/receive and Im not sure if this is related but when i hit or any user hits the send/receive button it will sit there processing the offline address book.  in exchange 2003 that use to zip through the entire process.  im not sure if in 2010 there is a difference.

the oab issue is surely not related to the ram usage this is a different subject and I would advise you to open another question for this.

when you "feel" emails are slower to go out, please go to the event log on exchange and check for any relevant errors or warning

thanks\

Yes I will do that.  I have looked at the event log and everything is clean.

are you talking about the issue of the OAB ?  if so open a new question for this one


for the rpc latency it should be low not high, also give me the details of your server specs maybe you are low on specs

no your sever is just fine for 22 users and if your rpc latency is low then I don't think you have any issue!
