Systems and methods for multi-thread processing of messages. An example method comprises: receiving, by a first processing thread, a plurality of network packets from a server; processing the plurality of network packets to produce a message; writing the message to a message queue; retrieving, by a second processing thread, the message from the message queue; producing a memory data structure based on the message; placing the memory data structure into a result queue; and responsive to determining that a total size of messages in the message queue exceeds a certain threshold, causing the first processing thread to suspend receiving network packets.
