Hello, I am trying to estimate the number of users I can hold on my rsync backup server if all users are connecting at about the same time. I am using rsync over ssh with 256bit-aes encryption. Here are my average server specs (from least powerful to most powerful): 2.8GHz P4 1GB Ram 1TB SATA w/ RAID 10 for 500GB usable space Kernel 2.4.32 with PaX-Enabled (causes moderate preformance decrease). hdparm shows: cache reads at 932 MB/sec buffered reads at 50 MB/sec ----- 3GHz P4 w/ 1MB cache 2GB Ram 1.5TB SATA w/ RAID 10 for 750GB usable space Kernel 2.4.32 with PaX-Enabled (causes moderate preformance decrease). hdparm shows: cache reads at 2,080 MB/sec buffered reads at 107 MB/sec All other servers specs are between the two above. Most clients are uploading <100MB of data @ 320kbps (at max 40KB/s) Few clients will keep longer connections uploading more, but a majority only sync under 100MB. Thank you for any help, I appreciate it! --Gian G. Spicuzza
