What is running on each of your end user terminals?

Are your servers 32bit or 64bit?
What is your average concurrent usage?
My guess would be that the issue is with your DB, nine times out of ten that's where I find performance bottlenecks. Can your DBA see what the activity on the DB looks like when issues are occurring?
One other thing to look at is your Anti Virus SW on the server. Make sure exclusions are set up for the appropriate directories. McAffee/Norton will eat your lunch if you let them.

If I may ask since we don't have a DBA what can be used to monitor the activity on the DB. We are having the same issues.
What are the exclusions needed within the anti virus?
thx,

The two main areas you should focus on are the application server and the
database, with the correct things enabled they will report how well things
are doing and give you a lot of pointers as to where to look.
Application Server:
1. Is the server swapping to disk? You may have oversubscribed the
available memory which would cause swapping and have a major impact on
performance. A good option in conjunction with monitoring the heap is to
reduce the initial heap size then watch to see if it eases the load (from a
memory perspective) on the server.
2. Heap logging - either track the available memory reported in
SystemOut.log or enable verbose garbage collection logging in WebSphere. Do
you really need 5 JVMS or are you allocation 4Gb of memory to each and
having it just sit there doing nothing?
3. User distribution - the benefits of your five JVMs are wasted if your
load balancing isn't working, track via SystemOut.log the number of users
per JVM and ensure you are not saturating one JVM.
Database:
1. Ensure that SQLTimeout in Maximo Properties is set to 1000 or a little
less, look through your SystemOut.log files and search for the phrase
"execution took", this will show any queries for which the round trip to
the database too more than 1000 milliseconds, look at optimizing any that
you find.
2. Database server - does it have enough memory? For example on Oracle
check the SGA and PGA sizes, also ensure that there is enough physical
memory available to meet what is allocated.

Our servers are 64bit.
We typically run 50-60 users.
Thanks for the idea to look at the DB server. I'll follow up with our DBA.
We are running MS Forefront. I am working on excluding all of the IBM directories from AV scanning.

If you only have 50-60 users I'd be inclined to either shutdown two JVMs or, maybe more cautious, set the initial heap size to 2Gb on all five and monitor if it grows. I've just seen an almost identical scenario at another client.
Reducing the initial memory will cause the heap to grow as required and give you a clearer picture of what you need to support your users. You can chart the heap usage from native_stderr.log using the IBM Support Assistant.
