More specifically, embodiments of the invention relate to managing the dedicated set of computational resources in a replication system during runtime in order to, among other things, improve the performance of the replication system. ## Claims ### Claim 1 A method for managing replication system processing, the method comprising: allocating a first set of cores to a replication application in a replication system; obtaining, by the replication system, data from a client device for processing by the replication application; processing the data by the replication application using the first set of cores; determining, based on the processing, a processing rate of the data by the first set of cores; making a determination that in the processing rate is greater than a breakpoint associated with the first set of cores, wherein the breakpoint corresponds to a modeled processing rate of the first set of cores, wherein processing the data obtained from client devices at a rate above the breakpoint results in an exponential drop in output of the replication application compared to incoming data rate; and based on the determination, updating the first set of cores to a second set of cores, wherein the second set of cores is allocated to the replication application. ### Claim 2 (depends on 1) The method of claim 1, further comprising: prior to allocating the first set of cores: selecting the first set of cores to evaluate; evaluating, by the replication system, the first set of cores to obtain performance data; and determining the breakpoint associated with the first set of cores using, at least in part, the performance data. ### Claim 3 (depends on 2) The method of claim 2, wherein the performance data is stored in a core profile in the replication system, wherein the core profile specifies a cardinality of the first set of cores. ### Claim 4 (depends on 3) The method of claim 3, wherein a core profiler, executing on the replication system, obtains the performance data and determines the breakpoint using, at least in part, the performance data, wherein the core profiler generates the core profile. ### Claim 5 (depends on 1) The method of claim 1, wherein determining the processing rate comprises logging a plurality of processing rates for the first set of cores over a period of time, wherein the processing rate is one of the plurality of processing rates. ### Claim 6 (depends on 1) The method of claim 1, wherein processing the data comprises: creating a copy of the data from the client device;
