It's my guess that the added rle is of such an advantage that it outweighs the choice between lzo or lz4. A lz4-rle could possibly be better than the lzo-rle, but likely only marginal.

zram: Compressed RAM-based block devices - Kernel

WebMar 13, 2024 · The table presents the performance metrics of different compression algorithms, including LZO, LZO-RLE, LZ4, and ZSTD. The metrics include throughput, compression ratio, and latency, which are important factors to consider for selecting the optimal compression algorithm. zram, formerly called compcache, is a Linux kernel module for creating a compressed block device in RAM, i.e. a RAM disk with on-the-fly disk compression. The block device created with zram can then be used for swap or as general-purpose RAM disk. The two most common uses for zram are for the storage of temporary files (/tmp) and as a swap device. Initially, zram had only the latter function, hence the original name "compcache" ("compressed cache"). 0050股價歷史
