      * [OPTIONAL] **--cancel-list-on-mount-seconds=0** : libFuse implicitly issues a list command on mount resulting into a call to container to retreive list of blobs. User can avoid this call by disabling the list feature for given number of seconds specified in this parameter. Default value is 0 meaning list call is not disabled.    
      * [OPTIONAL] **--high-disk-threshold=90** : High disk threshold percentage. When the disk usage reaches this threshold cache eviction resumes. This parameter overrides 'file-cache-timeout-in-seconds' parameter and cached files will be removed even if it is not expired. Files which are currently in use (open) will not be evicted from cache.
      * [OPTIONAL] **--low-disk-threshold=80** : Low disk threshold percentage. Stop evicting cache, which was triggered by 'high-disk-threshold' when disk usage returns back to level specified by low-disk-threshold
-     * [OPTIONAL] **--upload-modified-only=false** : If any file is open in 'write' mode then blobfuse upload that file on close, ir-respective of file was modified or not. Setting this flag to true means files will be uploaded only if they were modified after opening.
-     * [OPTIONAL] **--cache-poll-timeout-msec=1** : Timeout (milisecond) of checking the blobfuse cache for any possible eviction and free up space. Default is 1 milisecond.
-     * [OPTIONAL] **--max-eviction=0** : How many cached files shall be evicted at a time, in case multiple are expired. This is to conserve the CPU usage done for cache eviction. Remaining files will be evicted in the next turn. '0' means there is no upper limit and all expired files will get evicted, may result in 100% CPU usage.
-     * [OPTIONAL] **--set-content-type=false** : While uploading blob set the 'content-type' property based on file extension. Disabled by default, to enable set value to 'true'.
-     * [OPTIONAL] **--ca-cert-file=/etc/ssl/certs/proxy.pem** : If external network is only available through a proxy server, this parameter should specify the proxy pem certificate otherwise blobfuse cannot connect to the storage account.
-     * [OPTIONAL] **--httpsproxy=http://10.1.22.4:8080/** : If external network is only available through a proxy server, this parameter should specify the proxy server along with the port which is 8080 unless there are some deviations from normal port allocation numbers.
-     * [OPTIONAL] **--httpproxy=http://10.1.22.4:8080/** : Only used when https is turned off using --use-https=false, and if external network is only available through a proxy server, this parameter should specify the proxy server along with the port which is 8080 unless there are some deviations from normal port allocation numbers.
+     * [OPTIONAL] **--upload-modified-only=false** : Flag to turn off unnecessary uploads to storage. The default is false so any open file in write mode will get uploaded to storage. If you intend to upload only files that have their content modified set --upload-modified-only=true. Please note that if you set this to true changes to metadata only will be ignored and not pushed to storage. Setting this to true will prevent excessive billing from PUTs and improve perf.
+     * [OPTIONAL] **--cache-poll-timeout-msec=1** : Time in milliseconds in order to poll for possible expired files awaiting cache eviction. Default is 1 milisecond. Longer values may help performance.
+     * [OPTIONAL] **--max-eviction=0** : Number of files to be evicted from cache at once. Default is 0 meaning no limit. All expired files will be evicted. This value may be set to a number greater than zero to batch up cache eviction in different cycles so that 100% CPU does not get consumed by cache eviction. 
+     * [OPTIONAL] **--set-content-type=false** : Flag to turn on automatic 'content-type' property based on the file extension. Default is false so content-type will only be set if the uploaded file specifies it.
+     * [OPTIONAL] **--ca-cert-file=/etc/ssl/certs/proxy.pem** : If external network is only available through a proxy server, this parameter should specify the proxy pem certificate otherwise blobfuse cannot connect to the storage account. This option is only available from version 1.3.7
+     * [OPTIONAL] **--httpsproxy=http://10.1.22.4:8080/** : If external network is only available through a proxy server, this parameter should specify the proxy server along with the port which is 8080 unless there are some deviations from normal port allocation numbers. This option is only available from version 1.3.7
+     * [OPTIONAL] **--httpproxy=http://10.1.22.4:8080/** : Only used when https is turned off using --use-https=false, and if external network is only available through a proxy server, this parameter should specify the proxy server along with the port which is 8080 unless there are some deviations from normal port allocation numbers.
