Hi,

I tested this patch today and I fear the resulting value is too low.

For me, its leads to:

***SNIP***
...
2018/10/30 14:42:43 kid1| WARNING: All 2/2 redirector processes are busy.
2018/10/30 14:42:43 kid1| WARNING: 4 pending requests queued
2018/10/30 14:42:43 kid1| WARNING: Consider increasing the number of
redirector processes in your config file.
...

Current setting is "40" (Duo box, 2 Cores, 'squidclamav, squidguard)

Best,
Matthias
