The main drawback is latency. CXL memory accesses are too slow for normal CPU mechanisms to hide reliably, especially when each access depends on the result of a previous one. At the same time, they are too fast for traditional software techniques, such as context switches or interrupt-based asynchrony, to manage one load at a time. On a real Granite Rapids CXL platform, we find that placing GAPBS graph workloads in CXL memory slows execution by 2.44x on average compared with local DRAM.
