IIS Performance Issues

JPSealey

We are having performance issues with SafeGuard 5.5 client’’’’s sync'ing with the management servers whereby it takes an extraordinarily long time for them to properly register and receive the appropriate certificates and keys.

From looking at the management servers this issue would appear to be with the performance of the IIS servers; the w3wp.exe process consumes 100% of CPU time (of a single core) and the processes keep being recycled due to the following:

Event Type: Information

Event Source: W3SVC

Event Category: None

Event ID: 1077

Date: 14/09/2012

Time: 10:17:07

User: N/A

Computer: <server>

Description:

A worker process with process id of '5092' serving application pool 'SGNSRV-Pool' has requested a recycle because it reached its virtual memory limit.

For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp.

Has anyone experienced this issue and can offer some help to resolve the problem?

Cheers,

James

    Hi stone3825, thanks for the suggestions.

    We regularly run a clean-up of the events database as we have experienced issues because of this before. Sophos support have also recommended moving to SSL as this can be up to 40% more efficient so this will be looked at more very soon.

    However, the CPU usage on the servers can hit 100% even when there is only a handful (~10) of clients connected; I therefore suspect that there is something more fundamentally wrong.

    Any further suggestion gratefully received.
