Who’s the first team a User calls when the ECM application slows
down? The ECM team of course. But, nine times out of ten, slowness is caused by
effects of other systems. Whether it’s the database, network, or the User’s open
applications, sluggish performance has many sources.
Question: who’s working on what client, in what environment, and
where?
Network: we were fixing something
From Who: multiple sites simultaneously, or one building?
Large companies with multiple buildings most likely have
networks that are somewhat patched together leaving some Users with networks
that are performance subpar. Also, some areas of the company may be hugging
bandwidth with applications that are dragging the whole network down.
Database: This won’t impact the application…
From Who: All applications that use that db server, or one
application?
Typically, the database server is a shared environment
thanks to our buddies who consolidated individual servers at the expense of “decoupling”.
This shared environment could at the mercy of reporting for BI initiatives
slowing it down. If it’s an Oracle RAC, sometimes the nodes don’t reboot as
advertised. The shared environment of tier 1 applications, could put the other
lower tiers at risk because the lower ones will not be the priority if there’s
a business outage.
Backups: we were trying to restore another application
From Who: One application or many?
Backups might happen late at night during “off” hours, but
there’s still a performance hit on databases and file stores. There’s also the
possible wave of activity after a recovery that clogs all downstream
applications.
Security: we were hacked
From Who: One app, or many?
With new layers of security applied comes extra processing
thus potential for slowness. This is usually agreed upon at the design stages,
but complained about after implementation.
Virus protection: half of our share drive files are encrypted
I’ve had many times when I’m looking for causes of slowness
on my PC or on a server, only to find out that the task manager is showing a
huge percent of CPU being used by the virus protection software. Hint: Double
check when the full scan is scheduled.
User’s 5k open applications: who me?
If one User complains, log onto their PC and check out what applications
they are running (assuming they didn’t close some while they waited for you).
Try closing and opening Outlook. What’s in their startup folder? Check their browsing
history for views and downloads.
Service Desk: this is a routine patch
Even when the Service Desk is being proactive with mandatory
testing of patches to Windows or IE, there are always issues, especially with
interaction of multiple open web browser (“no footprint”) applications.
Upshot
When you get blamed for slowness of your ECM application
have a script of questions to ask to triage the issue. Check the possible
larger issues first and move toward the User at hand. Slowness happens because
everyone wants information faster, that is, in our zealousness to always get
faster we stumble occasionally.
