[OpenAFS] Apache and Openafs

[GALAMBOS Daniel]

Thanks, it's an odd solution to remove cpu cores but worked.
The server had 8 vCPU with 6GiB RAM. After I removed 6 vCPU, it worked
as a dream. WIth downloading thread with AB and 20 000 requests, the
load was about 4 and the avg response time was is 70 ms.

I don't want to believe that this workaround is the only solution. The
prod server has proxy servers for our users' and i concerned about if
the 2 vCPU will be enough. (But it's an other story, has no connection
to AFS)

Thanks,

Dancsa
