Server computer execution of client executable code

A data processing method comprising:

• receiving, at a server computer, a request from a client computer to provide a service of an application that the server computer hosts;
• acquiring a particular runtime from among a plurality of pre-computed runtimes in a runtime pool, each of the pre-computed runtimes in the runtime pool comprising an executable combination of computer program script code and context data that is programmed to create and use one or more data items having global scope;
• using the server computer, providing the request to the particular runtime and executing the particular runtime to cause generating a response to the request;
• transmitting the response to the client computer;
• cleaning up the one or more data items having global scope and returning the particular runtime to the runtime pool after completing the cleaning up.

• using the server computer, providing the request to the particular runtime and executing the particular runtime to cause generating a response to the request;
• transmitting the response to the client computer;
• deleting the particular runtime;
• asynchronously creating one or more new pre-computed runtimes and adding the new pre-computed runtimes to the runtime pool.

A computer system comprising:

• a virtual computing instance programmed to execute one or more worker processes each programmed to provide a service of an application to a client computer in response to a request from the client computer;
• digital memory that is accessible to the virtual computing instance and that stores a plurality of pre-computed runtimes in a runtime pool, each of the pre-computed runtimes in the runtime pool comprising an executable combination of computer program script code and context data that is programmed to create and use one or more data items having global scope;
• one or more sets of program code respectively implementing the one or more worker processes, each of the one or more sets of program code programmed to acquire a particular runtime from among the plurality of pre-computed runtimes in the runtime pool;
• to provide the request to the particular runtime and to execute the particular runtime to cause generating a response to the request;
• to transmit the response to the client computer;
• and to clean up the one or more data items having global scope and return the particular runtime to the runtime pool after completing the cleaning up.
