max connections

[djcart]

I'm testing my server at loader.io. I would like to increase the number of connections, but I still have values between 20-30. The settings in httpd-perclientconnlimit.conf had no effect. I currently have the following configuration:

perClientConnLimit{
staticReqPerSec 0
dynReqPerSec 0
outBandwidth 0
inBandwidth 0
softLimit 10000
hardLimit 10000
gracePeriod 15
banPeriod 300
}

I also checked the firewall if ip was not blacklisted during the test, but nothing appeared there.
