Drastically reduced performance with newest fw

    Currently I'm using AsusWRT
    Today I've upgraded it to the latest version. After the upgrade, the reading from an NFS service slowed down.
    (before the upgrade, reading a text file with about 30000 lines needed ~0.5secs, after the fw upgrade the same read operation ran ~4-5secs...)
    After a brief investigation I've found the source of performance degradation: I'm logging both accepted and dropped packets. In the earlier versions the log shows only packets from the WAN (ppp0) while the newer versions logs every packets which is in different IP range than the router's own.
    I'm using more IP ranges on my LAN ( for physical devices, for virtual machines).
    The newer firmwares are logging all traffic between and when I enable logging accepted packets and it causes this drastic slow down on my network.
    Is there any way to keep the latest firmware, logging both (accepted and dropped) packets but exclude the traffic on the device br0 (IN=br0 and OUT=br0 too) from the logs?

    Not enough info.

    1. What's your router?

    2. Most likely, you are not on the latest firmware since 384_45149 has been superceded for most popular Asus routers at this point in time.

    1st: It is an Asus RT-AC68U (It isn't significant IMHO)
    2nd: Pardon??? I've tried to upgrade to the latest fw, but I can't use it because of its slowness, caused by the new logging method...

    I'll admit this seems like a new issue to me which I haven't heard before. ;)

    If you can't change the logging method to something else that will allow you to upgrade the firmware to 45713 or RMerlin code, then a reset to factory defaults will. Possibly, a WPS NVRAM erase procedure will be needed too, along with a format the jffs partition on next boot cycle.

    When was the last time you performed a full reset to factory defaults?

    Please see my M&M Config (link in my signature below) link to get your router back to a good/known state.
