Incredible "slow internet"

noctiluca · 08-31-2011, 03:56 AM

All users have for some time experienced an exceptional bad performance when using their web browsers. We have used both the free antivirus and the Kaspersky antivirus. Connecting an ordinary PC outside the UT was an incredible difference.
Some sites took a long time to load. Others showed up when reloading the address, and yet others did not load at all.

Downloading worked well. Performance monitoring shows just nothing wrong. Could not see any DNS/nslookup problem either.
After shutting down the Kaspersky module things works better.

Both modules are configured to "Scan html", but nothing else are tampered.
The box is configured for automatic update every saturday. It seems to work.

What are the average cpu loads and free memory.

Also how free is the hard drive?

noctiluca · 08-31-2011, 05:28 AM

Memory: Free: 811 MB; Used: 1314 MB
CPU: 1,26% load

noctiluca · 08-31-2011, 05:30 AM

Disk: 59 GB free of total 70 GB

This is when the Kaspersky module is on?

Just the CPU and Ram (Memory) if not.

noctiluca · 08-31-2011, 06:32 AM

Oh, yes. The server has never used more than some percents of the CPU, and there has been good margins for the RAM.

One loose end of a theory is that the code at a certain point of the version upgrade has become slower, and each module multiplies the delay. If that is the case, then We could suddenly have a lot more delay than earlier, although we cannot see any difference in CPU/RAM load.

Turn on the attack blocker module and report back what it reports after your next day's logs. Odds are you've got someone running bittorrent (they may not even know it).

You mean Protocol Control, I assume.

Thats probably your issue.

btw, percent CPU is meaningless. Load is all that matters. what is the load?

No he means attack blocker. I would not suggest running untangle without attack blocker.
