Title: Antivirus scan Post by: bruno.pereira on Tuesday 22 May 2012, 06:09:07 am When I enable antivirus for http proxy or pop/smtp proxy, my "router" machine gets incredible slow..
Is there any reason for that? Title: Re: Antivirus scan Post by: rosch on Tuesday 22 May 2012, 08:56:18 am Slowing it a bit down is normal. But ideally you would not even see a difference.
Code: hdparm -tT /dev/hda The output should be close to the following: /dev/hda: Timing cached reads: 2296 MB in 2.00 seconds = 1146.54 MB/sec Timing buffered disk reads: 158 MB in 3.01 seconds = 52.42 MB/sec Also the output of Code: top Title: Re: Antivirus scan Post by: bruno.pereira on Tuesday 22 May 2012, 10:32:08 pm The output
Timing cache reads: 184 MB in 2.03 seconds = 90.64 MB/sec Timing buffered disk reads: 32 MB in 3.10 seconds = 10.06 MB/sec How much time does the AV take to start?

Are you running endian on one harddisk only? How much time does the AV take to start? That depends on your machine but it should not take long at all. It looks to me that it's only few seconds. But disk I/O is increased during the running of it. Could you post the output of top? Are you running out of RAM? If swap is used machines usually go down to a crawl speed.

I was using M0n0wall before...and it was ok, now I wanted to change to Endian just because of the proxy... Yes I'm using only one harddisk, it has 10GB. (But it's the machine that our supervisor allocated to use as router...so it's the option that we have.. We from IT department need to make some miracles... lol) |
