Subject linux mag: Roxen vs. Apache
Date Sat, 21 Mar 1998 21:07:35 GMT
Hi,

in the current german 'Linux-Magazin' appeared a review of Roxen Challenger
1.2. The article includes a performance comparison with Apache (no 
version number was given)...

Here are some infos/quotes:

server machine: 586-dual-board, P200MMX, 64MB RAM, 64MB swap, SCSI
client machine: 586-board, K6/200, 128MB RAM, 64MB swap, SCSI
(both machines where running Redhat 5.0 Linux w/ Kernel 2.0.32
and where connected directly via ethernet/10Mbit)

 "The client was running a C-program which forked 2 up to 192
  child processes which immediately send 2500 parallel requests
  to the server. For every request a new socket was used.
  [...] serverload was measured via 'top' [...]
  While Roxen produced a constant load of approx. 1.0, but
  consumed nearly all CPU-time, Apache enhanced the server-load
  to an unaccustomed value (up to 47.02), but the server was
  still usable due to a fluctuating idle-time (30-50%).
  [...]
  During the last test (192 child processes) the client
  encountered some 'connection-timed-out' errors with Apache.
  On all test runs Apache produced zombie processes up to a
  maximum of 43 on the last run.
  [...]
  The benefit of Roxen is the astonishing better stability
  in high load situations - although the throughput is smaller, yet
  the server load stays in a sane dimension, there are no zombie
  processes and no timeouts."


some values from the performance graphics...

server-load (peak value):

               Roxen   Apache
   4 clients    0.5       3
   8 clients    1.0       9
  32 clients    1.4      19
  64 clients    0.8      33
 128 clients    1.4      40
 192 clients    0.9      47

               Roxen   Apache
   2 clients     50     140
   4 clients     32      85

  16 clients      7      21
  32 clients      4      12
 128 clients      1       2
 192 clients     >1       1   



ciao...
