OTP-17796 Application(s): erts
Related Id(s): ERIERL-729, PR-5473
Responsiveness of processes executing on normal or low
priority could suffer due to code purging or literal
area removal on systems with a huge amount of
processes. This since during these operations all
processes on the system were scheduled for execution at
once.
This problem has been fixed by introducing a limit on
outstanding purge and copy literal requests in the
system. By default this limit is set to twice the
amount of schedulers on the system. This will ensure
that schedulers will have enough work scheduled to
perform these operations as quickly as possible at the
same time as other work will be interleaved to a much
higher degree. Performance of these operations will
however be somewhat degraded due to the overhead of
enforcing this limit compared to when using a very
large limit.
This limit can be set by passing the +zosrl command
line argument to erl, or by calling
erlang:system_flag(outstanding_system_requests_limit,
NewLimit).
