Hi!

This is an issue that I have seen many versions back.
I am using my KWF as an fileserver.
But everytime I copy files to or from the server, (No matter if it is an client or the server working against desktop share) the CPU works at 100% load, and it is the "winroute.exe" that takes all cpu.

I have tried to disable the winroute viruscanner, the server virusscanner and also setting "protocoll inspector" to none on the LAN rule. but it does not matter.. I get 100% everytime. It is only when copying files this happens.

All machines are running "windows XP pro" sp2, even the "server".

Has anyone an idea how to avoid the load?

Regards, Magnus Finbom

edit: currently im using KWF 6.2.1 Build 1454

What brand of network adapter do you use? Some adapaters are known to be problematic, such as realtek-based ones.

ahhh, interesting.
My Lan-card is an 3Com 3c905B.. rather old.. maybe I should try to switch to a newer card.

Hi!

The last thing I did was to disable "protocol inspector" for every rule.. I cant find any good and clear information on why it should be enabled, so Off it went. Smile (Anyone with som info??? )

I have also ordered an new NIC for the server, a real server-nic to replace my old 3com 3c905-card. I will report back here when finished.

regards, Magnus Finbom

The protocol instectors filter the traffic. Turning them off turns KWF into a 'simple' router. Turned on they take care of the virus-scanning, HTTP-rules, etc. You can turn them on/off per service or per traffic policy rule.

Problem is still here. After upgrading hardware to PD-930 and Intel dual gigabit ethernet adapter, CPU loading is still 90-100% when passing traffic thru KWF.

Hi!

Thanks for trying that. I was asuming that changing NIC not would solve this issue... Confused
But you saved me the job to replace nic in my server.

I suppose that we just have to live with this.

I don't know how to solve your problem, I'd suggest you take it up with Kerio directly (phone or submit a ticket).

I can only tell you such a high CPU load is not normal. I tested throughput and CPU load earlier today for another thread (this one) and got these results with the CPU only going up to 20% (I think perhaps 10-15% was needed for the KWF process):
                        DOWNLOAD      UPLOAD
Total transferred:      478,94 MB     10,84MB
Maximum transfer rate:  83,66 mbps    1,92 mbps
Average transfer rate:  69,27 mbps    1,57 mbps
Duration:               58,7 seconds

My server is a IBM eServer x336 with a single Xeon 3Ghz (as NIC's I use the 2 onboard Broadcom NetXtreme Gigabit Ethernet NIC's) running Windows Server 2003 R2.

Hope all this helps and good luck!

Machine:
Windows 2003 SP2
Kerio Control 7.0.0 (i use only routing and nat, other is off)
Celeron (Tualatin) @1400MHz
Two NIC 3Com 3C905C 100Mbit

CPU load at ~100% when i copy files through this machine (average speed ~10.5 MByte/s)

This 100% CPU load is normal?

i got the same issue an my new winroute machine...
set the box up a week ago and now i'm wondering why i can't get the full gigabit speed!
winroute.exe is taking 100% cpu load while copying files from the server.

my box:
via eden 1.2ghz
1gig ram
1,5TB
winroute 6.x

is there a fix or do i have to switch the gateway software?

greetings

Of course that cpu load is 100% can you imagine how many package must be checked??
you can solve this if you add one extra network card in and disable kerio layer driver on him!!

Question cannot be stupid, but some of the answers can.

It is! Disable kerio driver layer on some interface.
