Hello all,
We run an internal NNTP server to disseminate content. It's a poor
solution but it's been in place for so long that it's going to be a year
before we can pull it out. Right now clients are logging in to the NNTP
server and beating the heck out of it. The box is not performing well and I
need to find a better solution. That better solution probably involves
buying new hardware, but I don't know what to get.
If anyone has run NNTP under similar situations or can give me help I'd
really appreciate it
Currently we are seeing the following current statistics:
- 70k - 80k files daily. Most are news stories and are approximately
2kb in size. Some (5%) are pictures or audio clips as large as 2meg.
- Approximately 1.5 gigabytes of new content every 24 hours
- Peak loads are around 80 simultaneous connections
- Approximately 250 unique users log in over a 24 hour period.
This is all being served by a Sun 420, 1 gig of ram, and 2 330mhz CPUs.
Right now it is unknown where the bottlenecks are. They could be in iowait
(disk), memory swap usage, network bandwidth, TCP socket connections,
process forking, or other unknowns.
How are most of you running NNTP? Are you loadbalancing it on lots of Netra
T1's or are you running it off of a 4500? Which approach fits best?
