Apache's -- both 2.0.x (recent builds) and 2.2.3.
Has anyone else seen this? Is this just a lack of tuning? If so,
pointers would be appreciated.
Note we're using:
SendBufferSize 16384
and
EnableSendfile Off
Before blaming the latter setting, however, I should point out that the
problem we're seeing exists both for this case with simple static file
downloads and for dynamic downloads through mod_jk and Tomcat (we've
only tested this case with 2.0.x). The latter case is actually our
real issue, but unless/until static file downloads don't show this
degradation there seems to be little point in chasing the (more
complex) dynamic case.
Also the enabling send file does not seem to make any difference to the
results.
