> Modifying the scan server to perform more than one concurrent scan. When we discussed this, we realized there is an interesting tradeoff between isolation and caching. Running a single concurrent scan per scan server prevents a rouge scan that gobbles up all memory from negatively impacting other scans. On the other had running multiple concurrent scans per scan server enables scans to benefit from a larger shared cache (which may be useful if tablets are repeatedly scanned using the same scan server). -- This is an automated message from the Apache Git Service.
