PROBLEM TO BE SOLVED: To provide a thin client system for achieving the convenience of a user by shortening a time since the user actually performs an operation until the plotting of a screen is completed.SOLUTION: When one condition among one or more duplication conditions is satisfied by the state of the desktop of a client 20, virtual machine duplication processing S108 of a server 10 creates speculative execution processing S107 as a duplication of virtual machine processing S106. Assuming that an operation set for each condition is actually executed, speculative execution environment desktop processing S113 performs the speculative execution of the operation of a desktop. Screen transfer processing S105 transmits screen data after the speculative operation to the client 20. The transmitted screen data are buffered in a buffer part 203 of the client 20. When the operation is actually executed by the client 20, input/output control processing S202 instantaneously reflects the buffered screen data on a screen part 204. |
