Slow Web Filter Performance

SnakeyJ

We are seeing very slow performance from the Endpoint Webfilter at supported clients and our own site - typically 3-5 seconds delay before opening a new page!

Initially I thought this would be DNS related - but quick investigation points to slow response from Sophos Servers to the Webfilter clients.

If we have to do these looksup via the cloud, please provide the resource/bandwidth - currently the performance is so poor most of clients are turning it off!

Any comments welcome.

    Hmm, perhaps doing it all via the cloud is not the most efficient solution - may be the web filer could check against a local cache (managed via the enterprise console) and only refer queries for unknown / less commonly accessed sites?

    I'll have to to look at some capture to see exactly what is being requested, but the problem appears to be one of latency rather than bandwidth limitation.    Whilst it may not be practical to hold all this content locally, it seems quite ineficient for 2,500 clients to query the service everytime they access common used sites.

    Given the nature of the threat I want my clients to use this part of endpoint protection, but 3-5 second delays on page lookups is quite a major deterent.
