My Workstation takes so long time to start. It takes 15 seconds or so between the log messages below.
[DEBUG] [Workstation.Alert] new ThornhillAlert - 1,448,525,399,392 Console Summary Alert
[DEBUG] [Workstation.Feature] Saw Feature --> introscope.enterprisemanager.recordtype.fixedMapping.72 <--
Tcpdump shows 9Mbytes data transfer between EnterpriseManager.5001 and Workstation.*, and it takes 15 seconds because the network transfer rate is limited to 5Mbps.
What's Workstation transferring?
Is it possible to reduce this time in other way to expand the network bandwidth?
Isn't this issue already investigated by us via 00265610 ?
Anyways there could be bunch of things happening here including fetching dashboard metadata, initializing widgets n stuff but without any additional data for e.g thread dumps it's hard to pinpoint. Having large number of management modules\dashboards also affect workstation startup time, have you tried removing all MM's and then try, assuming issue is always reproducible ?
If not please try and add MM's back slowly to see if correspondingly WS startup time increases or not.
If there is a support issue opened I would recommend following up via that channel and provide:
-Thread dumps when this gap is observed
-Debug Workstation logs
Yes, support people helped us to understand what's going on via 00265610.
We finally found that it took long time to transfer Management Modules. Our customer wonders why CA doesn't allow Workstations to cache and fetch MMs partially. I'll post this idea later.
