Meteor FTP can be configured to maintain caches of the most frequently accessed files and directories. This can significantly increase performance by storing this data in dynamic memory and thus avoiding slow hard drive access requests.

The settings for best performance depend on the amount of available RAM in the computer and the number and size of the files and directories on the server. In general, the larger the cache the better. Ideally, the memory cache would be set large enough to contain all the files in the server. In that case, all files and directories would only be read from disk the first time they are requested by a user. Thereafter the data will be transmitted directly from memory, decreasing server response time. Note, however, that that it may be counterproductive to set the cache size bigger than available physical memory.

To cache requested files, check the “Cache files” check box and then set the desired RAM cache size.

For use with the CM500 IP, the Cache Files box should be checked with a file size of at least 100 kB.
