Hello idk if anybody will be able to help me but here is my problem. I Have crs309-1g-8s+in as main switch for uplink and local network + ccr1009-7g-1c-1s+ as router for my windows PC. Windows PC is connected with optical SFP+ to switch than to CCR1009 for that im using Vlan 100 (which is for my local network). I have also direct acces to my second PC witch is also connected throught CRS309 but i have linux there so PC is acting as router and he is not using CCR1009 to access internet. Everything is connected with 10G.
If im doing speedtest.net from linux my speeds are Download: 8034.78 Mbps Upload: 8330.92 Mbps.
If im doint Iperf from windows PC to Linux speeds are also good RX [SUM] 0.0-10.0 sec 11.0 GBytes 9.46 Gbits/sec TX [SUM] 0.0-10.0 sec 11.0 GBytes 9.48 Gbits/sec.
Problem is if im doing speedtest from my Windows to speedtest.net to same server like Linux im only able to gain speeds around 8200Mbps down and 4-5000Mbps up.
only diference is im using CCR1009 as router. Im not using any queues (i did test without firewall aslo) and im using Fasttrack. CPU is running only around 20-30% on down and 10%on upload so i dont see why shouldend be upload as fast as download. But im not able to measure more than 5000Mbps.
Im using Speedtest CLI on both pc´s. If im doing iperf against same server i can measure speeds around 8200Mbps for Upload but i need to start 10 threads to reach same reasult. So my question is If there is something on CCR1009 what can help with single TCP conection speeds or is there is something else what can i do in settings to help upload.
