It seems to depend mostly on the speed of your disk system. That's because it does a stat(2) on every file in your local tree. I use it over a 56K frame relay link. I used to run it on a P/90 with narrow SCSI disks. I recently moved it to a PII/400 with fast ultra-wide disks (IBM 34560W), and it's much faster. An update of the entire "src" tree (about a day old) takes under a minute. I have a plan to eliminate the disk thrashing, but haven't implemented it yet. Once that's done, I believe it will truly be limited by the network link, unless you've got a T1 or better, or really slow hardware. John -- John Polstra jdp@polstra.com John D. Polstra & Co., Inc.
