Hi  Gerold

several hints about your creeping server :

split your ONLY dbvol (10 gig) into several smaller volumes on differents
disks
backup your DB more regularly (you will loose 650 MB of DB data in case of
crash !)
Win NT 4 prefers TCPWINDOWSSIZE = 48 (16*3) rather than 63
If your DB is on a RADI5 vol, you will loose in perf. => move it to a
raid0 volume
  and use the TSM mirroring facility instead of WNT / RAID5 one
up to 100 concurrent sessions seems a bit too much for a single PIII 600,
even if
  your % SCHEDULED SESSION is 50
what's your disk config, how many, speed, size ?
