Preemptive TCP connections to reduce latency for proxies

A computer-implemented method comprising:

• receiving, at a proxy server, a plurality of active communications connection counts of a plurality of active communications connections that were active within a time period;
• wherein an active communications connection, of the plurality of active communications connections, has a connection type;
• grouping connections of the plurality of active communications connections into N groups, wherein connections in a group, of the N groups, are defined by a same IP address of the proxy server, a same IP address of a destination, and a same port identifier of the destination;
• wherein each group of the N groups includes connections that are different than connections in other group of the N groups;
• wherein the N groups are ordered based on numerosity of connections in the N groups;
• determining a K count of active communications connections selected from the N groups of active communications connection counts, wherein K is an integer greater than 1 and not exceeding N;
• for each count of the K counts of active communications connections:
• determining a relative percentage of pre-connected communications connections, having a particular connection type and included in the count, to be pre-connected by the proxy server and available;
• wherein the relative percentage is a ratio between a count of the K counts and a K count of a largest group of the N groups;
• determining whether the relative percentage of the pre-connected communications connections of the particular connection type is already pre-connected by the proxy server and is available;
• in response to determining that the relative percentage of the pre-connected communications connections of the particular connection type is not already pre-connected or available within the time period, pre-connecting one or more particular communications connections of the particular connection type until the relative percentage of the pre-connected communications connections of the particular connection type is pre-connected and available.

A non-transitory computer-readable storage media storing one or more instructions which, when executed by one or more computer processors included in a proxy server device also comprising a storage media, cause the one or more computer processors to perform:

• receiving, at a proxy server, a plurality of active communications connection counts of a plurality of active communications connections that were active within a time period;
• wherein an active communications connection, of the plurality of active communications connections, has a connection type;
• grouping connections of the plurality of active communications connections into N groups, wherein connections in a group, of the N groups, are defined by a same IP address of the proxy server, a same IP address of a destination, and a same port identifier of the destination;
• wherein each group of the N groups includes connections that are different than connections in other group of the N groups;
• wherein the N groups are ordered based on numerosity of connections in the N groups;
• determining a K count of active communications connections selected from the N groups of active communications connection counts, wherein K is an integer greater than 1 and not exceeding N;
• for each count of the K counts of active communications connections:
• determining a relative percentage of pre-connected communications connections, having a particular connection type and included in the count, to be pre-connected by the proxy server and available;
• wherein the relative percentage is a ratio between a count of the K counts and a K count of a largest group of the N groups;
• determining whether the relative percentage of the pre-connected communications connections of the particular connection type is already pre-connected by the proxy server and is available;
• in response to determining that the relative percentage of the pre-connected communications connections of the particular connection type is not already pre-connected or available within the time period, pre-connecting one or more particular communications connections of the particular connection type until the relative percentage of the pre-connected communications connections of the particular connection type is pre-connected and available.
