=== Choosing the best compression method === | === Choosing the best compression method === | ||
By using the IBM CMOD arsadmin command multiple times with the different compression methods (LZW16, OD77 OD77Lite) you can determine the best compression method for a specific type of document that will be stored in CMOD. | |||
;LZW16 | |||
: This compression method is based on the Lempel-Ziv-Welch compression method, similar to the .ZIP file format. It is fast, but offers relatively low compression. | |||
;OD77 | |||
: The OD77 compression method is proprietary to IBM Content Manager OnDemand. It provides the best compression ratio, at the expense of consuming a lot of CPU time, which means loading data into IBM CMOD with this method is slower than other methods. | |||
;OD77Lite | |||
: This is essentially the same as OD77, but allows for faster load times by sacrificing compression ratio. | |||
