Thanks for the efforts, Rainer. I'll have to look deeper -- perhaps there is some aspect of our configuration that is causing us the issues as they seem to be quite repeatable. -- Jess Holle Rainer Jung wrote: Hi Jess, I did some simple tests and was not able to reproduce your performance

Do your results differ when Windows XP is used as the client? I looked back at all our notes and though we tested with Solaris and Windows servers the client was always XP. Rainer Jung wrote: Hi Jess, I did some simple tests and was not able to reproduce your performance observations.

Hi Jess, I did some simple tests and was not able to reproduce your performance observations. Nevertheless I could observe a couple of strange things, but I doubt, if they are relevant to most use cases. First my setup: Apache 2.0.59 worker with mod_jk 1.2.20 and Tomcat 5.5.17 with normal

All in all I think that throughput for huge files is very good in both cases. I would expect, that most often it would be much more intersting to inspect scalability and system load (cpu/memory) for massive concurrency. When serving large files, downloads will run a long time because most often

FWIW, this was also seen in less scientific testing from a linux system to an XP client on the same 100Mbit network. Andy Jess Holle wrote: Apache and tomcat are both on the same Solaris 10 box and the network between client (XP) is 100Mbit. -- Jess Holle Rainer Jung wrote: If noone finds

If noone finds a reason for it, I can go into it during the weekend. I would try to reproduce and research on Solaris. Concerning your data for Solaris: Apache and Tomcat were both on Solaris? The same machine or different? Network between Client (Browser?) and Apache was 100MBit or 1GBit?
