What does this mean?Also, should rwin size be an exact multiple of 8192? For example, for 32k, it would then

be 32768. Or does it not matter? I noticed the tweak on DSLReports doesn't abide by this methodology. · actions · 2000-Aug-18 12:46 am · justin..needs sleepModjoin:1999-05-282031kudos:15Billion BiPAC 7800NApple AirPort Extreme (2011) justin Mod 2000-Aug-18 1:12 am Re: What causes CRC errors with my network card during internetYou should not get any CRC errors reported by your NIC unless there is a modem or NIC problem or a faulty ethernet cable.Collisions, yes, crc cisco definition CRC errors.. very unusual.. dont forget its problems between your modem and your NIC, not beyond that.. if the data from your ISP had CRC errors it would not get to your NIC in the first place.As for RWIN, it doesnt matter. Some versions of windows change it to be a multiple of your MSS, some dont. Since the window is never filled anyway, it doesnt matter the whether if it was, the last TCP data segment fitted in exactly or not... the RWIN is buffer space allocated to each active socket.. intended to hold data while an application is "too busy to read". Coincidently, a large window also encourages the other end to "fill up the pipe", and thats what gets you the speed increase.In reality, this per socket data buffer is nearly always empty since applications (IE etc) are almost always grabbing packets as fast as they arrive.Its a bit of a waste of memory really - if the OS actually preallocates a 64k buffer for every single active socket, there goes quite a chunk of your RAM. Since we dont have the source to windows, we cant check if thats what it actually does.[This message has been edited by justin (edited 18 August 2000).] · actions · 2000-Aug-18 1:1
