All transfers from Windows = XP boxes to our new FreeBSD 5.4 installation seem to be quite slow. The = 5.4 is located in a housing center and we try to access it from behind = 3MBit DSL lines. Instead of the expected ~320KByte/sec we only get = 220KByte/sec. If I use a FreBSD, OSX or linux machine behind the same = router to download stuff from our 5.4 machine, everything is in perfect = order. If I access 4.11 installations from the same Windows XP machines, = everything is fine as well: Linux -> 5.4: ~320K FreeBSD 4 -> 5.4: ~320K Windows XP -> 5.4: ~220K Windows XP -> 4.x: ~320K Prior to the 5.4 box we had a 4.11 machine at the same location, same = routers clients etc. Again: Until we changed the box download speed were = ok. MTU etc. seem to be correct as well. This also happens from several = locations with different setups, providers etc. always with the results = shown above. So we are pretty confident that some change between 4.X and = 5.4 breaks the transfer rates when it comes to Windows XP.=20 Do any of you have an idea where we could/should look for? Are there any = timing issues corrected/changed in 5.X? Regards, JP
