Hello,
for some time now we encounter a lot of performance problems with our Astaro System. We currently run 6.200 but the problems also occur under 6.201 and the lastest 6.1 release.
The effect is that paket communication seems to hang every now and then for between 10 to 30 seconds (e.g. when I log on to a remote server via SSH or when I try to open a website with my browser the initial DNS request takes really long or times out in most cases). Because of that I though it has something to to with our provider's DNS servers - but I ruled that out by using other servers and connecting to the internet without our Astaro box. Then I though it might be some malformed IPS rules. But deactivating IPS/DOS/Flooding etc. had no effect either.
The problems do not just occur with connections to the internet but also between LAN and DMZ. I did some more tests with different protocols. For example while downloading a test file with HTTP from DMZ to LAN I reached the full 100MBit/sec but when downloading the same file from the same server via SSH it was not faster then 10MBit/sec.
The firewall computer never was at its limits regarding bandwidth, CPU usage or RAM usage. The log files also give no clue.
Any hints or ideas will be really appreciated because I'm quite out of ideas and our employees are understandably getting on my nerves.
