Hi there, my setup is simple: 1 WAN + 1LAN no qos, no dpi, no app filtering. NOTHING. fully hardware offload,

just wanted to test bandwidth control (i have 1gig isp)

Set it like this, limit to 500mbps

instead of full speed i have slow upload speed. 40-50Megabits per second and 98% cpu usage

 what i am doing wrong?

 

 

screen with bandwidth control ON

just uploading 1 file to FTP

 

 

 

 

screen with bandwidth control OFF

just uploading 1 file to FTP

 

Why just uploading single file to FTP  calls 100% cpu?

Hi @YuriyB 

Thanks for posting in our business forum.

Bandwidth Control rule is set to ID 2, do you have a 1? Does it replace the current priority?

As you have enabled the BC, it will require the CPU to process and monitor each session/frame of the matching machine. So, normal to have a CPU surge.

Some monitor and firewall settings rely on the CPU instead of the hardware acceleration unit.

 

Your 1Gbps ISP, is that symmetrical 1Gbps?

I recommend you do this test that is without BC enabled with another WAN/LAN1 disabled(if that's your non-1Gbps WAN, just test the 1Gbps WAN).

 

I also require a diagram of your network with your server that receives the file specified in the diagram.

  @Clive_A  Hi

thanks for answer.

bandwidth control ID1 is disabled, WAN2 (backup), offline.

qos, dpi, load balancing everything is disabled.

just one lan and one wan.

Today I repeat my test. and made 3 min video:

 

https://youtu.be/5hWNXYvGpSc

 

first test with disabled bandwidth control:

uploading file to ftp ~200megabits

downloading same file  ~400megabits

zero cpu usage

 

second test with enabled bandwidth control with speeds 1000000/1000000 laugh:

uploading  ftp ~50-70megabits

downloading same file 40-50megabits

high cpu usage

 

 

enabled

disabled bandwidth control

uploading/downloading same file to onedrive no problem. speeds are 400+ cpu usage low (no difference bandwidth control enabled or disabled)

uploading/downloading same file to fexnet no problem. speeds are 400+ cpu usage low (no difference bandwidth control enabled or disabled)

uploading/downloading same file to google drive PROBLEM. speed ~100megabits cpu usage HIGH (with bandwidth control OFF speed is 400+)

 

 

 FTP File transfers are very slow.

just tested again and getting 49megabits :( on GIGABIT ROUTER

 

run speedtest during FTP upload shows me normal speeds. what?

 

Please check FTP and google drive upload on your lab/device

bandwidth control ON set to 1000000/1000000 (no limit)

uploading FILE1 and FILE2 file from two PCs at the same time to single FTP speed is ~30+30megabits

 

 

 

 

 

 

disable bandwidth control and upload speed is 200+200=400 :)

You aren't doing anything wrong.  There is a reason these are 50 buck routers and the equivalent Cisco gear is well over 1,000.  Everything is done is software, so features like shaping and deep packet inspection will absolutely redline the CPU.
