We are uploading several million small (~20KB) files. When using the 64-bit version of SmartFTP, the queue will grow to 700K - 900K files and consume up to 18GB of memory. Once the 8GB of physical memory is exceeded, SmartFTP slows down from 60,000 files per hour to less than 200 files per hour as the machine spends nearly 100% of its time swapping memory with the page file. Is there a setting to limit the queue size that I haven't found yet? Is there some other setting that will improve this situation?
