[clamav-users] Regarding ClamAV performance

[Narashimman Srinivasan]

Hi

In  custom target, testing of clamAV (0.101.2) scanning set of
files/folders when RFS is from SD-MMC appears
same time taken (~13 mins) with(~1.8GB)/without swap memory under 1 GB RAM.
On comparison clamAV (0.101.2) with Ubuntu host (6 GB, 64 bits), time taken
is always quicker (~42 secs).

Following is log where time taken is almost same for scanning single file
or set of files on custom target (1 GB RAM)
running with Linux kernel 4.9, where root file system is from  SD-MMC card.

Please let me know your valuable feedback.
