first thing i'd do is install another ftpd, and see if the performance problems are still there. if they are specify the kind of NIC you have, and specify if your testing this over a LAN or over a remote connection. or if your supporting multiple connections or what. i haven't personally run a ftpd on that kind of bandwidth in a long time, and when i did, the bottleneck was either the remote end or the local disks. also try to put/get files to another local ftp server on with your server as the client and see if theres any difference. and of course, next time specify what exactly about the performance are you not happy about and what are you expecting out of the system. if the performance problems go away with proftpd or wuftpd or something then the problem is in glftpd somewhere. the ftp/bandwidth test i do most often is downloading a full kernel from ftp.kernel.org (maybe another mirror is faster for you, kernel.org is only 10 hops/61ms from my 1meg dsl). course that doesn't test outbound bandwidth which i test by uploading stuff to one of my t1s, i have a t1 thats about 9 hops/48ms from my dsl(the routing on my dsl rules!) nate
