hostapd: is possible to increase/reach a decent speed?

My nmcli report those speed on wifi routers

Code:

    nmcli device wifi list
    Wufr1                   Infra  44    270 Mbit/s  36      ▂▄__  WPA2 WPA3    
    other                   Infra  11    270 Mbit/s  40      ▂▄__  WPA2
    other                   Infra  12    540 Mbit/s  37      ▂▄__  WPA2
    other                   Infra  2     540 Mbit/s  30      ▂___  WPA2
    other                   Infra  6     540 Mbit/s  30      ▂___  WPA2

the "Wufr1" is my AP with hostapd, why is limited to 270MB? Is possible to reach 540mb?
This is my hostapd.conf

Code:

    interface=wlan1
    bridge=br0
    driver=nl80211
    ssid=Wufr1
    hw_mode=a
    channel=36
    ieee80211d=1
    ieee80211n=1
    ieee80211ac=1
    wmm_enabled=1
    auth_algs=1
    ignore_broadcast_ssid=0
    country_code=IT
    macaddr_acl=1
    accept_mac_file=/etc/hostapd/hostapd.accept
    
    # WPA
    wpa=2
    wpa_passphrase=forget
    wpa_key_mgmt=WPA-PSK SAE
    wpa_pairwise=CCMP
    rsn_pairwise=CCMP
    sae_password=forget
    wps_cred_add_sae=1
    ieee80211w=2
    own_ip_addr=127.0.0.1
    
    #HT
    require_ht=1
    require_vht=1
    
    ht_capab=[HT40+][SHORT-GI-40][MAX-AMSDU-3839]

This is the driver.conf for server

Code:

    options 88x2bu rtw_drv_log_level=0 rtw_led_ctrl=0 rtw_vht_enable=2 rtw_power_mgnt=1 rtw_beamform_cap=0 rtw_dfs_region_domain=1 rtw_switch_usb_mode=1

and client

Code:

    options 88x2bu rtw_drv_log_level=0 rtw_led_ctrl=0

The connection is stable, but speed is very slow
For example using rsync

machine3 can get 10MB/s (very poor)

machine1 can upload to machine3 at..5MB/s (awful)

Any advice? Thanks

The rate column in nmcli output refers to the physical link rate of the connection determined primarily by the hardware, and the signal quality isn't very good either. The usual - try finding a less populated channel or improving antenna positions.
